Question

1) What happens when led nitrate is heated ? Write down the products and balance the equation .

2) What happens when ferrous sulphate is heated ? Wrote down the products and balance the equation.

Answer 1

1)
when lead nitrate is heated the reaction is as follows

2Pb(NO3)2 (s)  + heat -------> 2PbO (s) + 4NO2(g) + O2 (g)

here Pb(NO3)2 is lead nitrate.

PbO is lead oxide

NO2 is nitrogen dioxide 

and this is a decomposition reaction as lead nitrate splits up ito three elements when heat is supplied.

2) Dear Student,

Ferrous sulphate is green in colour. On heating, the green crystals are converted into a dirty-yellow anhydrous solid as it loses water of crystallization. When further heated, the anhydrous material releases sulphur dioxide and sulphur trioxide leaving a reddish-brown iron oxide.

2 FeSO4 → Fe2O3 + SO2 + SO3

Hope it helps You ⭐(^^)⭐
Thanks ⭐^_^⭐

Answer 2

when lead nitrate is heated .thermal decomposition reaction takes place as follows

2Pb(NO3)2 (s) + heat -------> 2PbO (s) + 4NO2 (g) + O2 (g)

here Pb(NO3)2 is lead nitrate.

PbO is lead oxide,nitrogen dioxide[NO2​] which appears as brown fumes and oxygen is produced.
