Q8 of 38 Page 3

Write balanced chemical equations for the following reactions.

Lead nitrate, on heating, decomposes to lead monoxide, nitrogen dioxide gas and oxygen gas . Calcium oxide reacts with water to form calcium hydroxide and heat is produced.
Solution

2Pb(NO3)2 (s)2PbO(s) + 4NO2(g) + O2(g)
(Lead nitrate) (Lead monoxide)
2) CaO(s) + H2O(l) Ca(OH)2(aq) + heat (Calcium oxide).
