Answer:
2 moles of CO2 will be produced
Step-by-step explanation:
Chemical equation for the reaction will be
Formaldehyde + oxygen → CO₂ + H₂O
H₂CO + O₂ → CO₂ + H₂O
Since the equation is already balanced so
Taking the mole ratios
1 mol H₂CO : 1 mol O₂ : 1 mol CO₂ : 1 mol H₂O
We can see that every mole of H₂CO produces 1 moles of CO₂ , which means that 2 moles of CO₂ are produced from reacting 2 moles of H₂CO with oxygen.
