Question

Write the balanced chemical equations for the following reactions and identify the exothermic and endothermic reaction.
i) heating of ferrous sulphate crystals
. ii) calcium oxide reacts with water.​

Answer 1

Explanation:

2FeSo4 give rise to fe2 +so2+so3

Answer 2

Answer:

i) The chemical equation for the heating of Ferrous Sulphate is :

FeSo₄ ⇒  Fe₂O₃ + SO₂ + SO₃

It is an Endothermic Reaction.

ii) The chemical equation for heating Calcium Oxide with water is :

CaO + H₂O ⇒ Ca(OH)₂

It is an Endothermic Reaction.

Explanation:

i) Heating Ferrous Sulphate Crystals produce Ferric Oxide, Sulphur Dioxide and Sulphur Trioxide.

ii) Heating Calcium Oxide with water produces Calcium Hydroxide also known as Slaked Lime.
