Question

Which products will be obtained when lead nitrate heated simply. write balance chemical reaction for their reaction.

Answer 1

Hii There!!

When lead nitrate is heated simply, the type of reaction taking place will be thermal decompostition reaction.

Chemical reaction:-

PbNO3-------->Pb +NO2+ O2

Lead nitrate is a white coloured compound,when it is heated it decomposes to give;lead oxide, nitrogen dioxide and oxygen.

Answer 2

When lead nitrate is heated simply, it decomposes to form lead monoxide, nitrogen dioxide, and oxygen.

• Lead nitrate is an inorganic compound, which appears as a white-colored powder. It is soluble in water and in dilute nitric acid

• Decomposition reaction is a reaction in which one complex reactant breaks down into two or more simple products. Decomposition of a complex substance occurs when the substance is strongly heated.
• When lead nitrate $Pb(NO_3)_2$ is heated, it decomposes to form lead monoxide $PbO$, nitrogen dioxide $NO_2$, and oxygen $O_2$
• The balanced chemical equation for this reaction is as follows:
  $2Pb(NO_3)_2 \xrightarrow{Heat} 2PbO + 4NO_2 + O_2$  
• Experimentally, we can see that when lead nitrate is heated, we obtain a brown-colored powder of lead monoxide, and brown nitrogen dioxide fumes, and if exposed to flame, it would burn vigorously, indicating the presence of oxygen gas.
