When acid reacts with metal carbonate, _______ is/are formed.

Correct option is D

The correct answer is (d) All of the options.
· When an acid reacts with a metal carbonate, the products of the reaction are salt, water, and carbon dioxide gas.
· The general reaction can be represented as: Metal carbonate+Acid→Salt+Water+Carbon dioxide
· For example, when hydrochloric acid reacts with calcium carbonate, the reaction is: CaCO3+2HCl→CaCl2+H2O+CO2
· Here, calcium chloride (salt), water, and carbon dioxide are produced.
Information Booster:
· Water: Formed as a result of the combination of hydrogen ions from the acid and hydroxide ions from the carbonate.
· Carbon dioxide: Released as a gas during the reaction, which can be observed as bubbles.
· Salt: Formed from the cation of the metal carbonate and the anion of the acid used
