Question

What happens when nitric acid and calcium oxide combine?

Answer 1

Calcium Oxide in water forms Calcium Hydroxide + Heat. The Calcium Hydroxide will react with the Nitric Acid by neutralization rxn to form Calcium Nitrate, Carbon Dioxide and Water + Heat (exothermic)

Explanation:

`CaO(aq) + HOH(l) => Ca(OH)_2(aq)` + `Heat`

`HNO_3(aq)` + `Ca(OH)_2(aq)` => `Ca(NO_3)_2(aq) + HOH(l) + CO_2(g)` + `Heat`
