Answer 1

Answer:

2Pb(NO3)2when is heated = 2PbO+NO2+2O2

So this means the yellow substance is lead oxide(PbO) a reddish brown has is NO2 which has brown fumes and the one which supports combustion is oxygen (O2)

See the numbers after the elements are in subscript and the numbers before the element lead and oxygen are used to balance the equation
