Observe the diagram given alongside and answer the following questions:
a. What do you observe when lead nitrate is heated?
b. Mention the two gases evolved equation for it.
c. Write the balanced chemical equation for it.
d. What is the type of chemical reaction called?
e. Give one more example of this type of reaction.
(a) The colour of lead nitrate is white. When lead nitrate is heated it decomposes to give yellow coloured lead oxide and brown coloured nitrogen dioxide gas is liberated.
(b) The two gases evolved during the reaction are nitrogen dioxide and oxygen.
(c) The reaction is as follows:
(d) This reaction is thermal decomposition reaction as lead nitrate gets decomposed on the application of heat to give corresponding compounds.
(e) The example of this type of reaction is as follows:
2FeSO4→ Fe2O3 + SO2 + SO3
