GENERAL HISTOLOGY

Detailed explanation-1: -When hydrochloric acid comes into contact with calcium carbonate, the following chemical reaction ensues: CaCO3 + 2HCl → CaCl + CO2 + H2O, which provides acid neutralization alongside the formation of byproducts.

Detailed explanation-2: -The balanced equation of CaCO3 + HCl → CaCl2 + H2O + CO2 is CaCO3 (s) + 2HCl(aq) → CaCl2 (s) + H2O(aq) + CO2(g). Balancing a chemical equation depends on the law of conservation of mass.

Detailed explanation-3: -The HCl is the limiting reagent and the CaCO3 is in excess.

Detailed explanation-4: -Calcium react with hydrochloric acid to produce hydrogen gas, when it reacts it produce bubbles of hydrogen gas and when large chunks of calcium react with hydrochloric acid it will explode because the heat energy is enough to ignite hydrogen to explode. So becareful when doing this experiment. Q.
