dioxide gas. Express this reaction in the form of a word equation.​

Answer 1

Explanation:

Nitrogen + Oxygen ⇌ Nitric oxide

Nitric oxide reacts with oxygen to form nitrogen dioxide.

Nitric oxide + Oxygen → Nitrogen dioxide

Nitrogen dioxide reacts with oxygen and water to form nitric acid.

Nitrogen dioxide + Oxygen + Water → Nitric acid

Calcium carbonate + Nitric acid → Calcium nitrate + Water + Carbon dioxide
