Question

1. The heat of combustion is a negative value. Do you think this indicates an exothermic or endothermic reaction? Explain.​

Answer 1

Exothermic

Step-by-step explanation:

Combustion reactions are almost always exothermic because it is an oxidation reaction that produces heat and in this case it would be considered to be exothermic but there are few cases in which it would be considered endothermic. Combustion of Nitrogen is endothermic because Δ is positive despite being a combustion reaction.
