Answer 2

The chemical equation you've provided appears to have some errors and is incomplete. It seems like you're trying to represent a reaction involving calcium carbonate (CaCO3) and hydrochloric acid (HCl), but the equation is not balanced and has incorrect formulas. The balanced equation for the reaction between calcium carbonate and hydrochloric acid is as follows:

CaCO3(s) + 2HCl(aq) → CaCl2(aq) + H2O(l) + CO2(g)

In this balanced equation:

• CaCO3 is calcium carbonate (a solid).
• HCl is hydrochloric acid (an aqueous solution).
• CaCl2 is calcium chloride (an aqueous solution).
• H2O is water (a liquid).
• CO2 is carbon dioxide (a gas).

This reaction represents the dissolution of calcium carbonate in hydrochloric acid, producing calcium chloride, water, and carbon dioxide gas as products. The balanced equation ensures that the number of atoms of each element is the same on both sides of the equation, preserving the law of conservation of mass.
