Answer:
585 kcal
.
Explanation:
- From the balanced equation:
<em>2Cl₂(g) + 7O₂(g) + 130 kcal → 2Cl₂O₇.</em>
130 kcal are needed to produce 2 mol of Cl₂O₇.
<em><u>Using cross multiplication:</u></em>
130 kcal are needed to produce → 2 mol of Cl₂O₇.
??? kcal are needed to produce → 9 mol of Cl₂O₇.
<em>∴ The energy required to produce 9.00 mol of Cl₂O₇ </em>= (130 kcal)(9 mol)/(2 mol) = <em>585 kcal.</em>
