Question

the main purpose of balancing chemical reaction is​

Answer 1

The reason for balancing equations in chemistry is to obtain the correct proportions of reagents and products for a given reaction.

Since chemical reactions do not change the atoms themselves, a balanced equation tells you how much product to expect for a given set of reagents.

Answer 2

Answer:

The chemical equation needs to be balanced so that it follows the law of conservation of mass. A balanced chemical equation occurs when the number of the different atoms of elements in the reactants side is equal to that of the products side. Balancing chemical equations is a process of trial and error.
