which of the following is the correctly balanced chemical equation for the reaction of ca(oh)₂ and hno₃?\no…

Explanation:

Step1: Analyze reactants and products

Calcium hydroxide ($Ca(OH)_2$) reacts with nitric acid ($HNO_3$) to form water ($H_2O$) and calcium nitrate ($Ca(NO_3)_2$).

Step2: Balance the equation

On the reactant side, we have 1 Ca in $Ca(OH)_2$, 2 H in $Ca(OH)_2$ and 1 H in each $HNO_3$. On the product side, we need to balance elements. For the nitrate - ion ($NO_3^-$), since calcium has a + 2 charge, we need 2 nitrate ions in $Ca(NO_3)_2$. So we need 2 moles of $HNO_3$. Also, the reaction of an acid and a base produces water. The balanced equation is $Ca(OH)_2 + 2HNO_3\rightarrow2H_2O+Ca(NO_3)_2$.

Answer:

D. $Ca(OH)_2 + 2HNO_3\rightarrow2H_2O+Ca(NO_3)_2$
