(ill) Write a balanced chemical equation to represent the above reactio​

Answer 1

1.) WHEN LEAD NITRATE IS HEATED, A REDDISH BROWN GAS, NITROGEN DIOXIDE IS EVOLVED AND YELLOW MASS FUSES WITH GLASS.

2.) DECOMPOSITION REACTION

3.) 2Pb(NO3)2------>2PbO+4NO2+O2

Answer 2

When lead nitrate is heated nitrogen dioxide gas that is brown fumes are produced along with oxygen. It is a type of of decomposition reaction in which a single substance breakdown into two or more products .the reaction is as follows
