Question

write a balanced chemical equation to represent the decomposition of X
​

Answer 1

he equation is ----

Lead (II) nitrate → Lead (II) oxide + Nitrogen dioxide + Oxygen

The balanced equation is----

2 Pb(NO3)2 (s) → 2 PbO (s) + 4 NO2 (g) + O2 (g)

The chemical name of white salt is Lead nitrate Pb(NO3)2.

The salt on heating produces brown fumes. This is so because the salt contains nitrate ion. This salt can be any nitrate but if the residue left after heating is yellow in colour it definitely implies that the salt is lead nitrate.

Hope it helps!!!
