Question

2Pb(NO3​)2​(s)→2PbO(s)+4NO2​+O2​(g) What is the yellow coloured substance formed?



1) lead nitrate

2) nitrogen dioxide

3) lead oxide

4) oxygen​

Answer 1

Answer:

Explanation:Lead nitrate on heating decomposes to lead monoxide, nitrogen dioxide and oxygen. 2Pb(NO3)2 = 2PbO + 4NO2 + O2. NO2 is liberated, along with oxygen, as a reddish brown gas. ... If however you keep heating dry Pb(NO3)2 crystals, around 470°C it does not melt but decompose.
