please tell this question

and tell the colour during thermal decomposition
​

Answer 1

Answer:

The solid residual product when thermal decomposition of lead nitrate takes place is lead (II) oxide ( PbO ) . The color of PbO is red . (5). The solid residual product when thermal decomposition of calcium hydroxide takes place is
