How many kilojoules of heat are released when 0.72 mole of oxygen gas are used to combust methane?
KonstantinChe [14]

0.72 mole of oxygen would produce 320.4 kJ of heat.

<u>Explanation:</u>

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:

= \frac{890}{2} X 0.72\\\\= 445 X 0.72\\\\= 320.4 kJ

Therefore, 0.72 mole of oxygen would produce 320.4 kJ of heat.
