Best Chemistry Tuition in Singapore


Chemistry tuition classes in Miracle Learning Centre is very useful. If you do not understand chemistry, you must definitely attend the chemistry tuition class at Miracle Learning Centre. Let us learn about compounds in this chemistry tuition lesson.

Your chemistry tuition teacher at Miracle Learning Centre will teach you about compounds. Compound consists of two or more elements chemically combined together. They are joined together chemically. Examples of compounds are carbon dioxide, limestone, glucose, copper(II) sulfate and zinc nitrate. Zinc nitrate is made up of zinc, nitrogen and oxygen. Glucose is made up of carbon, oxygen and hydrogen.

The following are the properties of compounds. Compounds are formed by chemical reactions, which usually involve an exchange of energy in the form of heat, light or both, with the surroundings. A compound has properties that are different from the properties of its constituent elements. The elements in a compound are joined together in a fixed proportion by mass. A compound can only be broken down into simpler substances by chemical methods such as decomposition, or processes that involves heating, exposure to light or passing an electric current through them.

The student at Miracle Learning Centre asked, " Is limestone a mixture or a compound? " The chemistry tuition teacher at Miracle Learning Centre replied, " It is a compound because it has a fixed proportion by mass. It has a chemical formula CaCO3. It is made up of calcium, carbon and oxygen, in the ratio of 1:1:3 respectively. Compounds have a chemical formula. "

Miracle Learning Centre hope you have understood the compounds and how it helps you to answer chemistry tuition questions. Do come to Miracle Learning Centre for more chemistry tuition lessons to learn more about compounds and chemistry.
