12. magnesium hydroxide is an ingredient in some antacids. antacids react with excess hydrochloric acid in the stomach to relieve indigestion. a. balance the reaction that occurs between mg(oh)2 and hcl. 1mg(oh)2 + 2hcl -> 1mgcl2 + 2h2o b. what are the mole ratios that would be used to determine the number of moles of mgcl2 produced when hcl reacts with mg(oh)2?

Answer

Explanation:

Step1: Identify reactants and products

The balanced chemical equation is $Mg(OH)_2 + 2HCl\rightarrow MgCl_2+2H_2O$. Reactants are $Mg(OH)_2$ and $HCl$, products are $MgCl_2$ and $H_2O$.

Step2: Determine mole - ratios for $MgCl_2$ production

From the balanced equation, the mole - ratio of $HCl$ to $MgCl_2$ is $2:1$ (2 moles of $HCl$ react to produce 1 mole of $MgCl_2$), and the mole - ratio of $Mg(OH)_2$ to $MgCl_2$ is $1:1$ (1 mole of $Mg(OH)_2$ reacts to produce 1 mole of $MgCl_2$).

Answer:

The mole - ratios are $HCl:MgCl_2 = 2:1$ and $Mg(OH)_2:MgCl_2=1:1$
