Answer #1

2H2S + 3O2 --------> 2H2O + 2SO2

2 moles of H2S react with 3 moles of O2

0.97 moles of H2S react with = 3*0.97/2 = 1.455moles of O2

1.455 moles of O2 is consumed

2H2S + 3O2 --------> 2H2O + 2SO2

2 moles of H2S produced 2 moles of H2O

0.97 moles of H2S produced 0.97 moles of H2O

2H2S + 3O2 --------> 2H2O + 2SO2

2 moles of H2S produced 2 moles of SO2

0.97 moles of H2S produced 0.97 moles of SO2
