Answer 2

The reactant, product and coefficient of the chemical equation are 2H⁺ and CO₃², H₂O and CO₂ and 2 respectively.

The chemical reaction is as follows:

2H⁺ + CO₃²⁻ → H₂O + CO₂

Chemical reaction is the reaction between two or more substances to form a new substance.

The reaction is between an hydrogen ion(cations) and a carbonate ion(anions).

Generally, the reactant of a chemical equation is on the left hand side of the equation while the product is on the right hand side.

The coefficient are in front of the elements or compound involve in the reaction.

Therefore, 2H⁺ and CO₃²⁻ are the reactant of the chemical equation and  H₂O and CO₂ are the product . The coefficient is the 2 in front of H⁺ .
