umka2103 [35]

Answer:

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

Explanation:

Hello,

In this case, since nitric acid is HNO₃ and strontium hydroxide is Sr(OH)₂ we can represent the balanced chemical reaction by equaling the atoms of strontium, nitrogen, oxygen and hydrogen at both reactants and products as shown below:

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

Best regards.
