Answer 2

Answer:

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.

H + O = H²O

H² + O² = H²O

2H² + O² = 2H²O
