Question

H2CO3 + Mg(OH)2 —> MgCo3 + H20

In the balanced chemical equation below, how many moles of water are created if 17.8 moles of acid react with excess magnesium hydroxide?

Answer 1

H₂CO₃ + Mg(OH)₂ --> MgCO₃ +H₂O

Since the equation is balanced and the acid is the limiting reagent, we see from the equation that one mole of the acid produces one mole of water. Thus 17.8 moles of acid react with excess magnesium hydroxide to produce 17.8 moles of water
