Balanced equation: 2 SO2 + O2 + 2 H2O → 2 H2SO4
a) From the coefficients, 2 mol SO2 → 2 mol H2SO4, so the ratio is 1:1.
Moles H2SO4 = 12.5 mol SO2 × (2/2) = 12.5 mol H2SO4
b) Coefficients give 2 mol H2O → 1 mol O2, so O2 = (1/2) × H2O.
Moles O2 = 20 mol H2O × (1/2) = 10 mol O2
a) From the coefficients, 2 mol SO2 → 2 mol H2SO4, so the ratio is 1:1.
Moles H2SO4 = 12.5 mol SO2 × (2/2) = 12.5 mol H2SO4
b) Coefficients give 2 mol H2O → 1 mol O2, so O2 = (1/2) × H2O.
Moles O2 = 20 mol H2O × (1/2) = 10 mol O2
