Why should a chemical reaction always be balanced
The law of conservation of matter
Matter can change form through physical and chemical changes, but through any of these changes, the matter is conserved. The same amount of matter exists before and after the change—none is created or destroyed. This concept is called the Law of Conservation of Mass.
Chemical equation
A chemical equation is used to represent any type of chemical reaction in which a reactant is converted into a product under some specific conditions. A Chemical Reaction is a process that happens when two or more species interact to produce a new product
Explanation
Example
Here,
ELEMENT | NO. OF ATOMS IN REACTANT SIDE | NO. OF ATOMS IN PRODUCT SIDE |
2 | 2 | |
6 | 6 |
Therefore, a chemical equation should always be balanced complying with the law of conservation on mass
