Question

a white salt upon heating decomposes to give brown fumes and a residue is left behind. name the salt and write the equation for the decomposition reaction

Answer 1

the white salt that is PB(NO3)2 called lead nitrate on heating produces brown fumes ....it suppose to contain nitrate ions...the residue left is to be a yellow substance....
equation.
2Pb(NO3)2->2PbO+4NO2+O2

Answer 2

1)the salt is lead nitrate... ✌☺✌

2) 2Pb(NO3)2--Heat-->2PbO+4NO2(is the balanced equation..) ✌☺✌☺✌☺✌☺✌☺✌☺✌☺✌☺✌☺✌☺✌
