Question Analysis:
The question asks us to determine the number of chemicals that produce dioxygen on heating. Dioxygen, commonly known as oxygen, is a gas that is essential for various biological processes. We are given a list of chemicals and we need to identify the ones that produce oxygen when heated.
Solution:
To solve this question, we need to identify the chemicals that undergo a decomposition reaction when heated, resulting in the release of oxygen gas.
List of Chemicals:
1. KCIO3
2. (NH4)2 Cr2O7
3. NH4NO3
4. NaNO3
5. KMnO4
6. K2Cr2O7
7. H2O2
8. Pb3O4
9. NH4NO2
Chemicals That Produce Dioxygen on Heating:
1. KCIO3: Potassium chlorate (KCIO3) undergoes decomposition when heated, producing oxygen gas (O2).
2. (NH4)2 Cr2O7: Ammonium dichromate ((NH4)2 Cr2O7) is a highly unstable compound that decomposes when heated, giving off nitrogen gas (N2), water vapor (H2O), and oxygen gas (O2).
3. NH4NO3: Ammonium nitrate (NH4NO3) is a compound commonly used as a fertilizer and an oxidizing agent. It decomposes explosively when heated, producing nitrogen gas (N2) and oxygen gas (O2).
4. NaNO3: Sodium nitrate (NaNO3) is a stable compound that does not produce oxygen gas when heated. Therefore, it does not fulfill the requirement.
5. KMnO4: Potassium permanganate (KMnO4) is a strong oxidizing agent that does not produce oxygen gas when heated. Therefore, it does not fulfill the requirement.
6. K2Cr2O7: Potassium dichromate (K2Cr2O7) is a compound commonly used as an oxidizing agent. It does not produce oxygen gas when heated. Therefore, it does not fulfill the requirement.
7. H2O2: Hydrogen peroxide (H2O2) is a compound that readily decomposes when heated, releasing oxygen gas (O2).
8. Pb3O4: Lead(II,IV) oxide (Pb3O4) is a compound that does not produce oxygen gas when heated. Therefore, it does not fulfill the requirement.
9. NH4NO2: Ammonium nitrite (NH4NO2) is a compound that decomposes when heated, releasing nitrogen gas (N2) and oxygen gas (O2).
Conclusion:
Out of the given chemicals, the following 6 chemicals produce dioxygen on heating:
1. KCIO3
2. (NH4)2 Cr2O7
3. NH4NO3
4. H2O2
5. NH4NO2
