To verify the Law of Conservation of Mass during a chemical reaction.
What is meant by a chemical reaction?
A chemical reaction is process by which one set of chemical substances is transformed to another. There are different types of chemical reactions such as:
Substances which chemically react are called reactants and the newly formed substances are called products.
A French chemist, Antoine Lavoisier, who is known as the father of modern chemistry, changed chemistry from a qualitative to a quantitative science. He proved that the mass of the products in a chemical reaction is equal to the mass of the reactants. There are no more atoms at the end of the chemical reaction than there were at the beginning.
The Law of Conservation of Mass states that matter can neither be created nor destroyed in a chemical reaction.
In this case, the total mass of the reactants = total mass of the products. Also, the number of atoms of hydrogen and oxygen in the reactants side and the products side are equal.
In this case, the total mass of reactants and products also are equal. The number of atoms at the beginning and at the end is equal as well.
In this case, total mass of reactants = total mass of products.
