0.72 mole of oxygen would produce 320.4 kJ of heat.
Explanation:
CH₄ (g) + 2O₂ (g) → CO₂ (g) + 2H₂O (ℓ) + 890kJ
According to the equation,
2 moles of O₂ produces 890 kJ of heat
So, 0.72 moles of O₂ will produce:
[tex]= \frac{890}{2} X 0.72\\\\= 445 X 0.72\\\\= 320.4 kJ[/tex]
Therefore, 0.72 mole of oxygen would produce 320.4 kJ of heat.
