Answer 1

Endothermic reaction:

The opposite of an endothermic process is an exothermic process, one that releases, "gives out" energy in the form of heat

Not endothermic reactions:

Formation of calcium oxide by the combination elements calcium and oxygen.

2Ca + O2 → 2CaO

Formation of ammonia by the combination of elements nitrogen and hydrogen.

N2 + 3H2 → 2NH3

Reaction of calcium oxide in water to form calcium hydroxide

CaO + H2O  → Ca(OH)2
