Answer 1

Answer:

Endothermic

2FeSO4 -> Fe2O3 + SO2+ SO3

Iron Sulphate on heating forms

Iron Oxide, Sulphur Dioxide And Sulphur Trioxide

Exothermic

CaO + H2O -> Ca(OH)2 + Heat

Calcium Oxide combines with Water to give out heat and form Calcium Hydroxide

Answer 2

Melting ice.

Evaporating liquid water.

Exothermic examples-rusting of iron (rust steel wool with vinegar)

the thermite reaction.

reaction between water and calcium chloride.

Explanation:
