Question

. In which of the following reactions do five total molecules of reactants produce four total molecules of products? (Points : 3) N2 + 3H2 2NH3 SnO2 + 2H2 Sn + 2H2O 2H2S + 3O2 2SO2 + 2H2O 2SO2 + O2 2SO3

Answer 1

N2 + 3H2 -> 2NH3 has 4 molecules of reactants because it has 1 Nitrogen molecule and 3 Hydrogen molecules. It also has 2 molecules of products because it has 2 ammonia molecules. Does that help?
