Balanced chemical equation for reaction of hydronium ions with calcium carbonate will be as follows:
2H3O+ (aq) + CaCO3 (s) => Ca2+ (s) + 3H2O (l) + CO2 (g)
In this balanced chemical equation, acidic aqueous solution of hydronium ion (H3O+) reacts with calcium carbonate salt (CaCO3) resulting in the formation of calcium cation (Ca2+) an alkali, that results in neutralization of excessive acid. It also forms liquid water (H2O) along with liberation of carbon dioxide gas (CO2). All acids stronger than hydrogen carbonate, provide their calcium salts dissolved in water yielding carbon dioxide, because a bare hydrogen ion has no chance of surviving in water.
To balance this chemical equation, 2 molecules of hydronium ions react with 1 molecule of calcium carbonate resulting in formation of 1 molecule of calcium cation, 3 molecules of water and 1 molecule of carbon dioxide. The reaction proceeds at room temperature.

Hope this helps :)
Answer:
Exothermic Reaction
Explanation:
The test tube feels hot as a result of an increase in temperature of the surroundings. This means that due to the reaction between zinc metal and hydrochloric acid, heat was released. The hot test tube indicates that this is an exothermic reaction.
Answer:
1
