Answer:
Heating (NH4)2Cr2O7 liberates a gas, which is the same gas that will be obtained by heating NH4NO2. This is because both compounds contain nitrogen and hydrogen, which can easily form the gas ammonia (NH3) upon heating.
Explanation:
Ammonia is a colorless gas with a pungent smell, and it is composed of nitrogen and hydrogen atoms. It is a weak base and can react with acids to form salts. Ammonia gas is commonly used in the production of fertilizers, cleaning products, and pharmaceuticals.
The reaction between (NH4)2Cr2O7 and heat produces nitrogen gas (N2), water vapor (H2O), and chromium oxide (Cr2O3). However, the nitrogen and hydrogen atoms in the ammonium ion (NH4+) can also combine to form ammonia gas (NH3), which is released during the reaction.
Similarly, when NH4NO2 is heated, it undergoes a decomposition reaction to form nitrogen gas (N2) and water vapor (H2O), along with ammonia gas (NH3). Thus, the same gas is obtained in both reactions.
On the other hand, heating NH4NO3 results in the production of nitrogen gas (N2) and oxygen gas (O2), but no ammonia gas is formed. Treating H2O2 with NaNO2 or treating Mg3N2 with H2O also does not produce ammonia gas.
Therefore, the correct answer is option 'A', heating NH4NO2, which produces ammonia gas upon decomposition.
