Question

All
the chemical
equations must be
balanced why? Guss the and write.​

Answer 1

Answer:

This is due to the law of conservation of mass. Brought into the light by Lavoisier, this law states that amount of matter in the universe is constant. This amount cannot be increased or decreased by the chemical reactions. To depict and conserve this law, equations must be balanced.

Answer 2

As per me ,

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