Types of Reactions in Organic Chemistry

Types of Reactions in Organic ChemistryChemists can study various types of reactions in organic chemistry. The types of reactions that they learn involve the chemical changes in compounds. These are called conjugation reactions.It is true that all chemical reactions involve changes in the molecules that make up the reaction. But some of these reactions may require just one atom, while others may involve two atoms. Some other types of reactions may involve more than one molecule, and some will involve the interaction of many molecules with each other.Before they can study the different types of chemical reactions, chemists must have a working knowledge of the properties of molecules. Molecules have different electrical charges and properties, and they are arranged in different molecules to form different compounds.Inorganic molecules, usually carbon, oxygen, hydrogen and nitrogen, have different properties and atomic numbers. They are also arranged in different arrangements, so that t he atom arrangement has changed from uncharged to charged. They have fewer electrons than ions, and more electrons than atoms. The arrangement of the atoms also determines the energy levels of molecules.The properties of an atom are determined by its atomic number and its arrangement. For example, the electron configuration of nitrogen is shown on a bar graph, as a straight line, and shown at the same time, the position of the nitrogen in the atomic structure is indicated. The charges of all the other atoms are indicated as small circles on the graph.All the atomic numbers, the position of the nitrogen atom, and the charge indicate the basic properties of an atom. An important fact about atoms is that there are four types of atoms, called isotopes.The second type of atom is the element which is found in both elements, as it is an isotope of the first type. An isotope is an atom which contains a different number of neutrons. Other atoms have even more neutrons than the second type, w hich is a positive number.There are various types of reactions that can be studied, such as hydration, reduction, oxidation, and polymerization. They are an important part of chemistry.

Test 2. Common entrance exams,11+/13+ Here is our second test for you to practice for the common entrance exams. Questions by courtesy of Galore Park for the ISEB board. At a funfair there was a stall where people could roll a die. (courtesy of Galore Park) ROLL THE DIE 1 to enter Choose your own die Roll a six and win 6 Tim thought about this and decided to have six tries, knowing that he'd spend 6, and thinking that he'd be bound to win 6 on one of his six rolls, so he couldn't lose! Since blue is his favourite colour, he choose a blue die and rolled it six times. He was dismayed to discover he didn't roll a single six. The numbers he rolled were: 5, 2, 3, 1, 2, 4 Tim claimed that the die must be biased! (a) (i) What do you think about Tim's strategy? (ii) Do you think the die was biased? The stall holder told Tim to choose another die and try again, free of charge. This time Tim chose a large gold coloured die and rolled 1 six times. (b) Do you think that this second die is fair? (c) Describe a sensible way to finding out if a die is biased. (d) Suggest a way in which the stall holder can be fairly certain that he will make money. Give an example of an event which: (a) is impossible (b) is very unlikely (c) is unlikely (d) has an even chance of happening (e) is likely (f) is very likely (g) is certain to happen

Challenges of Being a Personal Tutor

Challenges of Being a Personal Tutor The private tutors enjoy wide range of benefits in tutoring services. But however they need to overcome certain professional problems to bring success in their career. Personal tutors face some problems, especially when they are new to teaching industry. We can have focused discussion on problems faced by tutors and tips to resolve those difficulties. This guide will surely help new tutors and also the experienced ones to travel in the path of tutoring career successfully. Challenge 1: Teaching may become a frustrating job Challenge 2: Struggling to gain good reputation Challenge 3: Handling “No job” days Challenge 4: Getting advanced knowledge in teaching Challenge 5: Tutor being a motivator These are top five challenges that every tutor face in their profession. On going into detailed note, Challenge 1: Teaching may become frustrating job Each student has their own learning tactics and capabilities. Some may have good practical knowledge but some students are lazy and show disinterest in studies. Students may be playful or interactive or shows interest only on subjects they like etc. It becomes duty and responsibility of personal tutors to direct them to right path. Sometimes, as a teacher, you may feel annoying to handle these kinds of students. But be patience and guide those students to excel in studies. Challenge 2: Struggling to gain good reputation As new comers to tutoring field, you may have difficulty to gain good reputation from parents/students. But remember, it takes some time to win the competition in tutoring services. Initially concentrate on your tutoring work of teaching students in interactive manner, giving them homework, providing them real time examples, having fun while studying, etc. This will surely boost energy and positive aspiration in studies. Thus you gain good name among them. Challenge 3: Handling “No job” days: You may wonder what “no job” days are about. When you are new to teaching industry, students and teachers are unaware of you and your service. At the beginning you need to promote your profile to get teaching opportunities. Therefore you need to wait for a month or two to teach students. The best technique to expose your teaching knowledge is by joining the tutoring sites like tutorz.com and submitting your resume. Parents and students will see your resume and hire you for their subject specifications. You need not worry or wait for long time to get teaching tasks. Challenge 4: Getting advanced knowledge in teaching When you start gaining experience, you defiantly need to enhance your teaching skills. You may suffer lacking in competition when you don’t have knowledge in advanced subjects. For this problem you may attend certification classes and become certified personal tutors. You can implement those skills while teaching students. Challenge 5: Tutor being a motivator. In case of teaching disabled students or dyslexia students, tutors should be motivators. You may face difficulties while handling those students for first time. Analyze the nature of students, their learning capability and then teach them in their own ways. Therefore students feel relaxed and enjoy studying. You can say some encouraging stories in between studies. Hence you will become the most favorite tutor for them. To be a tutor is a gift and tutoring is one of the best services. Follow these techniques in your tutoring career to bring happy tutoring opportunities to you.

How to Prepare for Your Skype Interview

How to Prepare for Your Skype Interview image via http://www.linkedportugal.com/wp-content/uploads/2014/01/ScreenClip4.png 1.  It’s a real interview Maybe I’ve just heard one too many horror stories, but I’m über paranoid about something going wrong in a Skype interview.   Maybe it was the story about the man who was on a Skype voice call only to realize that his webcam was somehow on and that his interviewer could now see his tighty-whiteys and him picking his nose.   Maybe it was the story about the woman accidentally dropping her laptop only to reveal that she had dressed professionally only from the waist up.   Maybe the combination of these stories made me take a Skype interview just as seriously as the in-person version.   Whatever the case, be absolutely professional because it is a real interview that could either potentially lead to a very real job or internship or to a real embarrassing moment. image via http://www.webrecruit.co.uk 2.  Dress the part Rock that suit.   Wear the heck out of that skirt and blazer.   Make sure that your hair is perfect and that your teeth aren’t sporting last night’s broccoli and that you are basically ready for a work-attire photo shoot.   And definitely don’t wear a button-up on the top but your lucky superman boxers on the bottom unless you’re willing to take the risk that your interviewer may get to glimpse your favorite superhero during a discussion of your past work experiences.   Bottom line: get dressed to go out for an interview and then just sit down and open up your laptop instead. image via http://www.investigationleaders.com 3.  Choose your surroundings carefully Again this comes down to being professional, and presenting yourself in a professional environment is crucial.   Don’t conduct your interview in front of the NSYNC poster that you’ve enhanced with your 5th grade lipstick kisses.   Don’t sit in your bed or outside or in the kitchen.   Make sure that you place your laptop on a level surface like a desk or a table so that the picture doesn’t shake distractingly and mess up your Skype interview. image via http://phunutoday.vn 4.  Test your connection You do not want to have to pantomime “I can’t hear you” to your interviewer as soon as the Skype call begins.   If the technical difficulties are on his or her end then there’s nothing that you can do about it, but you should absolutely check that your own computer is up to speed before the interview.   It literally takes less than a minute (you just push the “test call” icon on your Skype homepage) and could potentially save you from having to spend your interview diagnosing the problem instead of talking up your superb advertising skills. image via http://i.huffpost.com 5.  Look at the camera We are all taught to maintain eye contact during a conversation, accomplishing this looks different over Skype.   The natural thing to do is to look into the interviewer’s eyes on the screen, but this will make it seem as if you are looking slightly down as opposed to in his or her eyes.   Instead, look at the camera the entire time.   This may need a little bit of practice (especially when it’s distracting to look at yourself to make sure that you look as stunning as usual) but it can make a huge difference.   Making eye contact is crucial to presenting yourself well. image via http://static.framar.bg So just prepare thoroughly, think quickly, and good luck on your Skype interview!

Learn About the Chemistry of Matter

Learn About the Chemistry of MatterAleks chemistry is a very interesting subject that involves the experimentations of the chemical reactions in the natural world and the chemistry of matter. Chemistry is a field that deals with all kinds of natural materials that affect or react to one another to create something new. It is an intricate field that focuses on both the creation and analysis of chemistry by placing science behind all branches of scientific research.The world of chemistry is very vast and it deals with the natural elements, chemical reactions, and natural substances. These substances are what most of us know as elements or compounds. In chemistry, there are different types of elements that have properties and their chemical reactions are classified under different chemical groups. There are four basic groupings of chemistry that are all used in scientific research: organic chemistry, thermochemistry, inorganic chemistry, and nuclear chemistry.Hydrogen and oxygen make up what is commonly known as H-O-N and these two are commonly found in water. These elements react with one another by creating molecular bonds and give the different products in chemistry. Hydrogen and oxygen are also present in all the natural forms of matter, however the concentration and type vary. The main types of H-O-N are:Oxygen is a great example of a material that reacts with itself a lot and this is a reaction where one component dissolves into another. When a solution is heated, the molecules of the solution will be forced to combine and dissociate into the different components. By using a microscope to view and identify the reactions involved, it will be easier for scientists to take the right decisions for research and studies on the properties of matter.Oxygen is the only element in the universe that is naturally present, however in modern times, it is created through the use of other elements or compounds like carbon, hydrogen, and others. Most of the scientific resear ch focuses on the production of oxygen by combustion and other process and using atomic force and laboratory equipment. Although the concentration of oxygen is high, the concentration of other elements in the atmosphere is less compared to the concentration of oxygen.Another scientific study in the field of chemistry is the use of laboratory equipment such as x-ray devices and gas chromatography. The use of laboratory equipment has increased over the years and this is because the need for scientific research is getting bigger. Scientists nowadays depend on laboratory equipment in order to understand the properties of these materials and how they react.Most of the time, it is very difficult to understand the properties of natural materials if they are not exposed to the chemical processes that make them up. Using various instruments in a lab environment is highly recommended to use for the study of materials. Therefore, do your research on the materials of which you use every day and be sure to expose yourself to the various materials so that you can understand and appreciate the properties of nature.

Benefits of Using a Computer As a Tutor When Studying For a Computer Engineering Course

Benefits of Using a Computer As a Tutor When Studying For a Computer Engineering CourseThere are plenty of benefits to taking an online computer engineering course and in this article I will be looking at what makes the Internet so appealing for people who want to study or do research on a topic, but lack the time to do so. Although computer engineering has advanced to a level where you don't need to be physically present, a benefit is that you can easily access tutorials, videos and books, which you can do from home or from the car, and even take your laptop to places where you would normally not have the opportunity to visit.We've all used the internet, whether it's using your own computer or using a phone, as we've all found ways to share information with family and friends, use the internet for everyday tasks like banking, shopping and travelling, or as part of our hobby or hobbyist pursuits. In many cases, the benefits of the internet are actually more valuable than what you get out of it, as by studying or doing research online, you can get more help and information than you would get from a lecture.Physical courses are often very restrictive and the options for subjects are severely limited, whereas the internet has all sorts of subject choices, from games to physics to military engineering. By using a computer as your instructor, it means that you can be physically present for many of the lectures and also can gain additional information by watching videos and listening to the lectures. In some cases, you may also find that you are able to be physically present when you are studying, as it helps with concentration.The other benefit is that the cost of going to a university can become out of reach for some people, as you don't need to pay tuition fees or have to have a good computer science degree to qualify for entrance. A computer engineering course online can be paid for out of pocket, so can be much cheaper than if you were to go to university, espec ially if you are only looking to complete a second level course in Computer Engineering.Another great advantage of going to a university to do a computer engineering course is that you'll have access to many teaching materials and advisors, which are usually part of the study program. For many people, the cost of living is higher when compared to living in university towns, and a tutor at the university may have access to a more flexible schedule than an online tutor can.If you want to study at a local university, you may be limited in the classes that you can study and may have to get an advanced degree or postgraduate qualification to get into the university. Online courses, which can be completed at your own pace, usually allow you to study any course, from classes that are supplementary, such as music and drama, or a course like French, where you will receive certificates and further qualifications when completed.One of the biggest benefits of going to a university to study a co mputer engineering course is that you'll get the benefit of being physically present for the lectures and tutorials. Even if you decide to drop out, you still get a diploma from a university and your portfolio will show that you are a person who went to a university to study computer engineering.

Taking Physics Courses

Taking Physics Courses A Physics Degree Can Offer So Much Chapters10 Great Reasons To Study PhysicsHow To Find A Physics And Maths TutorHow Much Does A Physics And Maths Tutor Cost?What Kind Of Job Can You Do With A Physics Degree?Although the sciences of biology, chemistry, and physics often have a reputation in school for being particularly difficult or challenging subjects, the truth is that they are some of the most rewarding subjects that you can study.Physics, for example, can help teach you more about how things work, as well as teach you about the laws and phenomena that guide our universe.What’s more, physics is a highly in-demand degree at the moment, particularly in certain sectors such as teaching, where there is a shortage of qualified teachers entering the classrooms to teach a new generation of students.So, if you’re thinking about what degree you could take at university and you have an interest in physics, it’s definitely worth researching the benefits of taking physics at university.There are plenty of different phys ics degrees and physics courses available at universities. For example, you could study:Applied physics;Astrophysics; orTheoretical physics, to name a few.You can also study physics either as a single subject or in conjunction with another such as mathematics.Equally, it’s important to do your research on which university would be best for you to attend to study physics. Looking at a variety of institutions, from Oxford and Cambridge to UCL and beyond, is well worth doing, and if you can attend their introductory open days and have some interaction with current students to find out more about the curriculum and the lectures they attend then so much the better.Equally, you should be able to find out more about a particular physics course from the physics department at that university, which should have its own website outlining the kind of work they do and courses they offer.If you’re still unsure about whether physics is the right subject for you, or you’re not confident that your knowledge of physics is enough to enable you to do well at university, this article highlights some of the benefits of studying physics at university, and also offers some suggestions as to how you can improve your academic performance in the subject.You can learn more about the universe and how it works with a physics degree. (Image Source: CC0 1.0, WikiImages, Pixabay)Asking your teacher for help after class if there are certain points you have not understood, for example in relation to a particular experiment, or areas such as equations of motion, special relativity, electromagnetic fields, or nuclear reactions; andBuying a revision guide to help you prepare for upcoming exams.Of course, another way to try to improve your marks in physics is to hire a physics and maths tutor. A physics instructor can be a great help, regardless of whether you hire one just to help you through the exam season or if you have one to help you throughout the academic year.This is because a tutor can provide you with the extra motivation you might be lacking to succeed in your studies, can teach you about aspects of the physics syllabus you might not be comfortable or confident with, and can let you know about different exam techniques and approaches that can help prepare you for the day of your exam.What’s more, if hiring a tutor is something you’d be interested in, it’s also worthwhile considering whether you’d be best placed to hire a physics and maths tutor to help you.As physics and maths are very closely linked as subjects, and physics requires a high level of numeracy in order to perform well in the subject, sometimes just improving your ability in maths can be a real help when improving your marks in physics.When it comes to finding a maths and physics tutor, there are a number of different places that you could look.For instance, you could ask your teacher if they have any recommendations for tutors, or if they would be available to tutor you themselves.Equa lly, you could ask your friends studying physics and maths whether they use a tutor, and if so if they would recommend the one that they’re currently using to you.If you prefer to make your search for a tutor relatively easy and quick, you can also use online tutoring websites such as Superprof to find your next maths and physics tutor.By entering your postcode and the subject you’d like tuition in, you’ll be matched with tutors within your local area, as well as those that can provide online tuition if you’d rather have remote lessons.If you want to hire a tutor to help you with your physics course, it's a good idea to know what your budget is in advance. (Image Source: CC0 1.0, PublicDomainPictures, Pixabay)How Much Does A Physics And Maths Tutor Cost?It can sometimes feel as though half the battle of getting a good physics and maths instructor is finding one in the first place that is local to you (or willing to do remote lessons) and has the relevant experience that youâ €™re looking for.However, another important factor that needs to be considered when it comes to finding your next physics and maths tutor is the matter of cost.Although you’re likely looking at hiring a tutor to improve your academic performance, the truth is that it’s not worth hiring a tutor that is out of your price range, as this can quickly suck your finances dry and may well mean you don’t have access to the amount of tuition that you’d ideally like to have.When it comes to the cost of a physics and maths tutor, there are a few different factors to keep in mind:How experienced is the tutor in question? A brand new tutor is unlikely to charge as much as a tutor with years of experience;Where will the tuition be located? Sometimes, the price of tutors in cities with high living costs such as London can be higher;What you can realistically afford to pay per hour of tuition; andWhy you need tuition in the first instance (e.g. for revision preparation, general course assist ance, etc.).All of the above can have a dramatic impact on how much any prospective tutor will charge for their services.As an example, say that you would like a tutor for a few weeks just so they can help you revise a couple of well-known areas related to basic physics that may come up in the exam, such as topics related to waves or particles, electricity, electromagnetism, momentum, or radiation, or if you have a question related to a particular equation or principle.The price of tuition for such services is likely to be lower than if you wanted a maths and physics tutor for the entire academic year to help you with particularly complex or involved areas of the syllabus, for example, areas such as quantum mechanics, classical mechanics / Newtonian physics, cosmology or astronomy.So What Can I Expect To Pay?As a very general rule, physics tutors tend to charge between £15 and £30 per hour for their services. However, there are tutors out there that charge more and some that charg e less.The key to finding a tutor for the best price is to understand your own budget from the outset and to communicate this with your tutor so that they know whether they will be able to meet your budget’s requirements.You can also try different ways to save money on tuition, such as by opting to have online rather than in-person lessons, asking your tutor whether they are open to the idea of offering a discount, having condensed lessons, and choosing group tuition over one to one tuition.A physics degree can give you access to lots of different career opportunities. (Image Source: CC0 1.0, Free-Photos, Pixabay)What Kind Of Job Can You Do With A Physics Degree?When deciding whether a physics course at university is right for you, part of your decision should factor in what kinds of career opportunities there are likely to be for a physics graduate once you have completed your three or four-year undergraduate course.Thankfully, physics is a wonderful subject to study at universit y when it comes to career prospects. This is for a wide number of reasons:It teaches you transferable skills that many employers highly value;You can work in a number of different industries and roles; andIt paves the way for further academic study.For example, a physics degree should help teach you to employ analytical and critical-thinking skills, as you’ll have to interpret a wide variety of data and get used to problem-solving as part of your degree.These kinds of skills can be highly prized by employers â€" for example, investment management firms that need people who have good mathematical skills and can model spreadsheets and analyse figures.What’s more, having a degree in physics doesn’t mean that you have to work as a laboratory assistant, physicist, or scientist. You don't even have to work in labs or take a job specifically linked to your field. Rather, your career path can be very flexible.So if you’d like to be a mathematician, journalist, accountant, engineer, investment analyst, or work for the government, a degree in physics can help you achieve your goal.Another great aspect of physics is that it can be a great degree to have as an undergraduate degree if you’re looking to progress on to further study. Many physics undergraduates decide after completing their undergraduate degree that they would like to stay at university and pursue a master’s degree or even a PhD.While some students may keep studying physics, others may choose to take a master’s degree in a different discipline â€" again, there are lots of different routes to choose from.If you need any assistance finding out more about what you can do with a degree in physics, don’t be afraid to contact your school’s career adviser, or even consult a website such as Prospects, which is a great resource for finding out more about what career paths a degree could potentially offer.
