Looking for a chemistry tutor?

Chemistry is probably a very boring subject for many students. No matter how you teach the subject, some students simply do not like it. Before you look for a chemistry tutor, there are certain things that you need to take note. For many years, the main technique used in teaching chemistry is to attend classes conducted by a chemistry tutor. Many tutors are still using this method. There is nothing wrong with it, but you must understand that each student is different. The tutor must be able to convince the students to start studying. 

Once the student has the motivation to study, he or she is more likely to perform well. In fact, students can find a lot of motivation from their chemistry tutors. Chemistry has to be engaging for the students and the subject must be taught in such a way that it can captivate interest. This will keep the child interested, and will be more likely to be motivated to do well. 

The right chemistry tutor may be the key to your child success. Chemistry may pose a new challenge to your child, but this challenge can be easily overcome. By giving your child or yourself enough practice, you will soon notice a change in the examination results. If you or your child does not like chemistry, then you will need to find the best chemistry tuition classes to help yourself or your child.

Home Tuition for Yourself

As a student, it is very important that you do well for the examinations. However, you may have a hard time trying to keep up with the school syllabus. This is nothing surprising, especially when the education system in Singapore is very stressful. If you are looking for home tuition, it is very important that you look around for someone who can help you achieve the desired results. Getting a home tutor is probably one of the best choices that you can consider today.

And as we all  know, each and every one is different. Our learning ability is also different. In some cases, students may not be able to keep up with whatever that is being taught in school. Each student is different, and you cannot compare yourself with other people. There are some students who are able to achieve good results easily, but others may need special attention. Private home tuition becomes a necessity for those weaker students. As long as you are able to find someone who can help you out, achieving good results can become a reality in no time. There are definitely benefits to getting home tuition.

As for myself, I've been teaching maths and science for almost 10 years. If you are looking for physics, mathematics or chemistry tuition, please contact George at 81287561. I will be able to help you out.

Getting Home Tuition In Singapore

Getting home tuition is very important, especially if your child or yourself is struggling with a particular subject. It is important that you understand how to use the right tuition services. Getting a home tutor will be able to solve your problems. The reason why many parents are willing to pay high tuition fees is because they wish their children to do well in the examinations. Therefore, if you are looking for home tuition in Singapore, you might want to take the time to do some basic research.

Home tuition has become one of the most sought after services in today's information era. Consider getting a tutor from a tuition agency. Your child might be doing very badly for his or her examinations, and you're probably worried as well. There are many tutors who are willing to help your child out. 
Before you choose a home tutor from a tuition agency, it is always advisable to find out more first. I'm sure you do not want to spend too much money on home tuition as well. You must also understand that a tuition agency is very different from a tuition centre. A tuition agency will only refer tutors. A tuition centre, on the other hand, will be required to teach the students. In Singapore, the tuition centre should also be registered with the Ministry of Education (MOE).
If you are looking for affordable home or group tuition, please do not hesitate to drop me a call. Please contact George @ 81287561.

Test for oxygen and carbon dioxide gases

To test for oxygen gas, use a glowing splinter.

Observation: If oxygen gas is present, it will rekindle / relight.

To test for carbon dioxide gas, use limewater (calcium hydroxide)

Observation: If carbon dioxide gas is present, it will give a white precipitate with limewater.

Reactions of metals with hydrochloric acid

Zinc, aluminium and iron will form metal chlorides and hydrogen gas.

Copper does not react with hydrochloric acid because it is unreactive. Copper is below hydrogen in the reactivity series, therefore it is unable to displace the hydrogen ions.

Preparation of salts

There are 3 ways to prepare salt in the lab, and I will show you how to remember which are the techniques to use for the different salts.

1. Precipitation - this is only for preparation of insoluble salts e.g. lead (II) chloride, barium sulfate & lead (II) carbonate.

2. Titration - this is for the preparation of soluble salts, such as sodium, potassium & ammonium.

3. Acid + excess insoluble substance - usually for other soluble salts, less the ones listed in method 2.

I will go into details how this is done during my tuition classes.
