Question

what happens when lead nitrate is burned and crystals if feso4 are heated

Answer 1

Hola..!!

When Lead nitrate is burned, it decomposes to Lead oxide and oxygen and with a emission of brown fumes which are of Nitrogen dioxide.

And when Ferrous sulphate crystal is burned, it loses water and the colour of the crystal changes. It then decomposes to ferric oxide, Sulphur dioxide and Sulphur trioxide.

Hope it helps..

Answer 2

When lead nitrate is heated it decomposes to form :

a. Lead oxide

b. Nitrogen dioxide

c. Oxygen

In equation we can write it as :

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

This type of chemical reactions are called thermal decomposition reaction.
