Write balanced molecular equation for the reaction between nitric acid and calcium hydroxide. Express your answer as a chemical

eimsori [14]

<u>Answer:</u> The balanced chemical equation for the reaction of nitric acid and calcium hydroxide is written below.

<u>Explanation:</u>

A balanced chemical equation is defined as the equation in which total number of individual atoms on the reactant side is equal to the total number of individual atoms on product side.

The balanced chemical equation for the reaction of nitric acid and calcium hydroxide follows:

$2HNO_3(aq.)+Ca(OH)_2(aq.)\rightarrow Ca(NO_3)_2(aq.)+2H_2O(l)$

By Stoichiometry of the reaction:

2 moles of nitric acid reacts with 1 mole of calcium hydroxide to produce 1 mole of calcium nitrate and 2 moles of water molecule.

Hence, the balanced chemical equation for the reaction of nitric acid and calcium hydroxide is written below.
