Question

a white salt on heating decomposes to give brown fumes and a reduced left Behind :-(!)name the salt (!!) write the equation for decomposition reaction

Answer 1

The salt is Pb(NO3)2.
Pb(NO3)2----->PbO+NO2+O2

Answer 2

(1) lead nitrate pb(no3)2. (2) 2pb(no3)2------ 2pbo+ 4no2 +o2. Brown fumes = nitrogen gas yellow residue= pbo. By_ product = o2
