Final answer:
In the balanced chemical reaction for the neutralization of calcium hydroxide with nitric acid, the coefficient of nitric acid is 2, indicating that two moles of nitric acid react with one mole of calcium hydroxide to form water and calcium nitrate.
Step-by-step explanation:
The student is asking about the balanced chemical equation for the neutralization reaction between calcium hydroxide and nitric acid. In a neutralization reaction, an acid reacts with a base to form water and a salt.
The balanced chemical equation for this reaction is:
Ca(OH)2 (aq) + 2 HNO3 (aq) → Ca(NO3)2 (aq) + 2 H2O (l)
This equation indicates that one mole of calcium hydroxide reacts with two moles of nitric acid. Therefore, the coefficient of nitric acid in this balanced reaction is 2.
