Give one example of a combination reaction which is also exothermic.

Slaked lime [Ca(OH)₂] is formed when quicklime or calcium oxide (CaO) reacts with water.

A significant amount of heat is released during this reaction.

As a result, this is an exothermic reaction.

CaO (s) + H₂O --> Ca(OH)₂ (aq) + heat

Calcium oxide(quick lime) + water  calcium hydroxide(slaked lime)

Final Answer:Carbon dioxide is produced by burning carbon in the presence of oxygen, which is an example of a combination reaction that is also an exothermic reaction.
