Balance the following chemical equations and identify the type of chemical reaction.
(e) CaO(s) + SiO2 (s) → CaSiO3 (s)
(f) H2O2 (l) → U V H2O(l) + O2 (g)

Solution: (e) Cao(s) + SIO₂(s) + CaSIO₃(s)

This reaction falls under the category of Displacement reactions

(f) 2H₂O₂ (I) — UV → 2H₂O(I) + O₂ (g)

This is a decomposition reaction.
