Question

Describe the chemical balance of pb (no3)2=pbo+no2+o2

Answer 1

Answer:

2 Pb(NO3)2 → 4 NO2 + O2 + 2 PbO

Explanation

This chemical change is based on the property of color change  which the thermal decomposition of lead (II)nitrate.

Lead nitrate , which is a white color crystalline solid when heated changes into lead oxide which is yellow in color and a reddish-brown gas which is nitrogen dioxide with a colorless , odorless and tasteless gas which relights a glowinReactants:
