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.

What is a balanced chemical equation Why should chemical equations be balanced?

A balanced equation is when the amount of molecules reacting are equal to the amount of molecules being produced. Chemical equations must be balanced because no energy/mass is ever lost when a reaction takes place. This is because atoms are simply arranged.

What information are conveyed by a balanced chemical reaction why is it necessary to balanced a chemical equation?

A balanced chemical equation conveys the correct molar ratios of reactants and products in a reaction. Balancing a chemical equation upholds the Law of Conservation of Mass, which states that matter cannot be created or destroyed.


Why should chemical equation be balance?

According to Law of conservation of mass - The mass of matter can neither be created nor be destroyed. So, th no. of mass in reactants and products in chemical eequation should be same. To satisfy this Law chemical equation should be balance.
