Question

if 100.0 molecules of H2 and 40.0 molecules of O2 react how many molecules of H2O can be produced in the reaction below? 2H2(g)  O2(g) to 2H2O(g)

Answer 1

In the reaction 2 H2 + O2 = 2 H2O number of produced molecules H2O is the same as that of twice the number of molecules of O2 which is the minor component. There will be 80 molecules of H2O produced
