Question

9. Give balanced chemical equations representing the following reactions.
(a) On being heated with chlorine, iron forms iron(III) chloride.
(b) Carbon dioxide dissolves in water to form carbonic acid.
(C) When burnt in oxygen, magnesium forms magnesium oxide.
(d) Hydrogen reacts with chlorine in sunlight to give hydrogen chloride.
(e) When heated with sulphur, iron forms iron(II) sulphide.​

Answer 1

Answer:

●Fe(s) + 3 Cl2(g) → 2 FeCl3(s)

● HCO3− + OH− ⇌ CO32− + H2O

● Mg + O 2 → 2MgO

●chlorine radical reacts with hydrogen radical to form hydrogen chloride.

● Fe + S → FeS
