Question

In the following reaction identify the products formed and balance the equation.

HNO₃ + CaCO₃ ⇢?

Answer 1

• The balanced chemical equation is an equation where the number of atoms of different elements on the reactant side is equal to the number of atoms of the elements present on the product side of the reaction.
• It provides quantitative information about that reaction.
• It also indicates the molecular proportion of substances in the reaction.
• In the given equation HNO₃ + CaCO₃$\to$

When nitric acid (HNO₃) reacts with calcium carbonate(CaCO₃), it gives calcium nitrate (Ca(NO₃)₂), carbon dioxide(CO₂), and water(H₂O).

• The balanced chemical equation is

2HNO₃ (aq)+ CaCO₃ (s)⇢ Ca(NO₃)₂ (s)+ CO₂ (g)+ H₂O(aq)

Hence the products are calcium nitrate (Ca(NO₃)₂), carbon dioxide (CO₂), and water (H₂O).
