Answer: 0.113 moles of NaCl are created as a result of decomposing 12 grams of
.
Explanation:
To calculate the moles :

The balanced chemical equation for decomposition of
is:
According to stoichiometry :
2 moles of
give = 2 moles of 
Thus 0.113 moles of
give =
of 
Thus 0.113 moles of NaCl are created as a result of decomposing 12 grams of
.
I am guessing you want us to balance this equation so.
To balance, we add another molecule of HCl to the left side of the equation and another molecule of water (H20) to the right side of the equation to give:
<span>Mg(OH)2 + 2HCl = MgCl2 + 2H20 </span>
