Hydrogen sulfide gas reacts with oxygen to produce sulfur dioxide gas and water according to the balance equation:
2H2S + 3O2 → 2SO2 + 2H2O.
How many moles of oxygen gas are required to react with 5.6 moles of hydrogen sulfide?

Respuesta :

2 mol of H2S react with 3 mol of O2

5.6 mol of H2S react with =5.6×3/2=8.4 mol of O2
