Answer 1

Answer:

Four reactions of decomposition -

1. 2FeSO4(s) -----> Fe2O3(s) + SO2(g) + SO3(g) [by heat]
2. CaCO3(s) -----> CaO(s) + CO2(g) [by heat]
3. 2Pb(NO3)2(s) -----> 2PbO(s) + 4NO2(g) +O2(g) [by heat]
4. 2AgCl(s) -----> 2Ag(s) + Cl2(g) [by sunlight]

Answer 2

Answer:

ca(oh)2 gives cao + h20

mgoh gives mgo +h20

caco3 gives cao +co2

pb(no3)3 gives pbo +no2 +o2
