Answer: 2 moles of CO₂ are produced from reacting 2 moles of H₂CO with oxygen.
Explanation:
1) Chemical equation:
Formaldehyde + oxgyen → CO₂ + H₂O
H₂CO + O₂ → CO₂ + H₂O
2) That equation is already balanced
3) Mole ratios
1 mol H₂CO : 1 mol O₂ : 1 mol CO₂ : 1 mol H₂O
4) Then, every mol of mol of H₂CO produces 1 mol of CO₂ , which means that 2 moles of CO₂ are produced from reacting 2 moles of H₂CO with oxygen.
