how many moles of Cl2 will be produced from the reaction of 9.61 moles of HCl? MnO2 + 4HCl = MnCl2 +Cl2+2H2O
4 moles HCl will produce 1 mole Cl2.
So 8 moles HCl will produce 2 moles Cl2.
1 mole HCl will produce 1/4 mole Cl2.
So 9.61 moles HCl will produce ?? mole Cl2.
Look at the coefficients. They TELL you how the reaction takes place.
