10 moles of HCl is added to excess to magnesium and forms 4 moles of h

1.	10 moles of HCl is added to excess to magnesium and forms 4 moles of hydrogen gas. percentage yield is 40percent or 60 percent
Answer» Answer:neither 60 nor 40 but 80 percent Explanation: the REACTION should be LIKE this 10hcl +5mg --> 5h2 +5mgcl2 *i have balanced it. the rxn shows 5 mol of H2 shoild have been produce but only 4 mol has produced.so (4/5)100 is 80 percent so both options are INCORRECT!**
