The balanced chemical equation for the reaction between Sulphuric Acid (H2SO4) and Calcium Hydroxide (Ca(OH)2) will be as follows:

H2SO4 + Ca(OH)2 `->` Ca SO4 +2 H2O

One molecule of Sulphuric Acid and one molecule of Calcium Hydroxide will react to give one molecule of Calcium Sulphate and two molecules of Water.

FYI- Calcium Hydroxide is a base and Sulphuric acid is an acid. Whenever an acid reacts with a base, a salt is formed along with water molecules.
