Consider the reaction MnO2 + 4HCI → MnCl2 + Cl2 + 2H2O. If the both the
reactants have a mass of 100 grams, which of the two will be used up first? How
many grams of MnCl2 will be produced after the reaction? (MnO2 =
86.94 g/mol, HC1 = 36.46 g/mol, MnCl2 = 125.8 g/mol)
Calculate
1 mol of reacts with 4 mol of , 1.15 mol of reacts with 4.6 mol of
in excess
HCl will be used up first - it limiting reagent.
According to the equation we get 1/4 mol of from 1 mol of HCl, therefore:
