Consider the reaction of magnesium metal with hydochloric acid to produce magnesium chloride and hydrogen gas. If 3.85 mol Mg and 3.85 mol of HCl are reacted, how many mol of oxygen are left over?
I balanced the equation and got Mg(OH)2+2HCl=MgCl2+2H2O.
Can you please walk me through the steps and not just give the answer?

    Your equation is not correct. The correct one is Mg + 2HCl ==> H2 + MgCl2

    You have mixed up two problems. There is no oxygen in this problem.
