Question

How much heat will be released when 0.750 moles of carbon monoxide (CO) react in an excess of oxygen gas?2CO(g) + O2(g) → 2CO2(g) + 566 kJ

Answer 1

When 2 mols of CO reacts it releases the 566 KJ heat
\[\rm 0.750 ~mols~of~CO \times \frac{566 ~KJ}{2 ~mols~of~CO}\]

Answer 2

calculate that you will get the answer.
