Question

Which of the following is the correctly balanced chemical equation for the reaction of Ca(OH)2 and HNO3?

Answer 1

Step-by-step explanation:

The reaction between calcium hydroxide and nitric acid is as follows.

`Ca(OH)_(2) + HNO_(3) \rightarrow Ca(NO_(3))_(2) + H_(2)O`

Number of reactant atoms are as follows.

• Ca = 1
• O = 4
• H = 3
• N = 1

Number of product atoms are as follows.

• Ca = 1
• O = 4
• H = 2
• N = 3

To balance the given chemical equation, multiply
`HNO_(3)` by 2 on reactant side and multiply
`H_(2)O` by 2 on the product side.

Therefore, the balanced chemical equation will be as follows.

`Ca(OH)_(2) + 2HNO_(3) \rightarrow Ca(NO_(3))_(2) + 2H_(2)O`
