Question

Find the chemical equation of marble dissolves in hydrochloric acid to give calcium chloride water and carbon dioxide

Answer 1

ooooooooooooooookkkkkkkkkkk

Answer 2

Answer: The chemical equation is given below.

Explanation:

Main composition of marble is calcium carbonate. The chemical formula for the main composition of marble is $CaCO_3$

The chemical equation for the reaction of marble with hydrochloric acid follows:

$CaCO_3+2HCl\rightarrow CaCl_2+H_2O+CO_2$

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.

Thus, the chemical equation is given above.
