What is a balanced chemical equation why should the chemical equation be balanced?

Answer 1

A balanced chemical equation is when both the products and the reactants are balanced, or have the same number of atoms on each side of the equation. For example:

2H20 --> 2H2 + O2

This means there are 2 water molecules as the reactants (before reaction) and 4 hydrogen and 2 oxygen atoms as the products (after reaction).

Technically the equation wouldn't work in real life if it weren't correctly balanced.

Answer 2

A balanced chemical equation is one in which the number of atoms of each element is the same on both sides of the equation. This is important because it obeys the law of conservation of mass, which states that matter cannot be created or destroyed in a chemical reaction. Balancing the equation ensures that the reactants and products are correctly represented in terms of the number of atoms involved.

Answer 3

A balanced chemical equation has correct placed coefficients and a representative chemical equation need these coefficients.

Answer 4

there must be a coefficient in front of each chemical formula
