Answer:
"The Story of an Hour" is a short story written by Kate Chopin on April 19, 1894. It was originally published in Vogue on December 6, 1894, as "The Dream of an Hour". It was later reprinted in St. Louis Life on January 5, 1895, as "The Story of an Hour".
- Lead nitrate is an inorganic compound. Lead nitrate is a white coloured powder. Lead nitrate is soluble in water and dilute nitric acid.
- We know that a reaction in which one complex reactant breaks down to two or more simple products is known as a decomposition reaction.
- Decomposition of a complex substance occurs when the substance is strongly heated.
The molecular formula for lead nitrate is Pb(NO3)2. When lead nitrate is heated it decomposes to form lead oxide, nitrogen dioxide and oxygen.
The reaction is as follows:
2Pb(NO3)2→2PbO+4NO2+O2
From the reaction, we can see that lead nitrate decomposes on heating and forms lead oxide, nitrogen dioxide and oxygen. Thus, lead nitrate on decomposition gives lead oxide, nitrogen dioxide and oxygen.
Thus, the correct answer options are (A), (B) and (C).
