Given the balanced equation: H2 + Cl2 2 HCl ,

Question

how many moles of HCl will be produced if 18.4 g H2 reacts with 127 g Cl2?

Answer 1

moles of H2=18.4/2=9.2moles
Moles of Cl2=127/72=less than 9.2
so the reaction is controlled by the amount of chlorine.

You will get twice the moles of HCl than you had of chlorine.

Answer 2

46
