What Is A Chemical Equation And What Are The Points To Be Remember While Writing A Chemical Equation?
To understand a chemical change and to study the different factors which controls it, has always been a focal points in the efforts of a chemists. To achieve these objectives we should have an appropriate way of representing a chemical change. Fortunately the chemists have developed a very suitable way of representing a chemical change in terms of symbols of elements and formulas of compounds. Representing the chemical change in this way is called a chemical equation. A chemical equation tells us the elements or compounds which are reacting and those, which are being produced as a result of this reaction. The reacting substances are called reactants and those which are produced are called products. It is customary to write the reactants on the left side and products on the right side. An arrow head drawn from the reactants to products separating them. The following points must be kept in mind while writing a chemical equation: (1) A chemical equation must obey the law of conservation o
