Answer:
Theoretical yield of hydrogen is 1.11 g
Explanation:
Balanced equation,
As Mg remain present in excess therefore HCl is the limiting reagent.
According to balanced equation, 2 moles of HCl produce 1 mol of .
Molar mass of HCl = 36.46 g/mol
So, 40.0 g of HCl = of HCl = 1.10 moles of HCl
Hence, theoretically, number of moles of are produced from 1.10 moles of HCl =
Molar mass of = 2.016 g/mol
So, theoretical yield of =
