Question

Marble dissolve in hydrochloric acid to form calcium chloride water and carbondioxide

Answer 1

Explanation:

The chemical equation for the reaction of marble with hydrochloric acid follows: By Stoichiometry of the reaction: 1 mole of calcium carbonate reacts with 2 moles of hydrochloric acid to produce 1 mole of calcium chloride, 1 mole of water and 1 mole of carbon dioxide.

Answer 2

All mineral acids react with Marble forming salts with the liberation of CO2 gas. Marble is chemically calcium carbonate i.e. CaCO3 .

When dilute HCl is added to calcium carbonate, it forms calcium chloride, water and carbon dioxide.
