Answer 2

How to obtain HNO2 from Ca(NO2)2

To obtain HNO2 from Ca(NO2)2, a chemical reaction needs to take place. However, it is important to note that Ca(NO2)2 does not directly convert into HNO2. The reaction involves the decomposition of Ca(NO2)2 to produce CaCO3, H2O, and CO2. Here is the balanced chemical equation for the reaction:

Ca(NO2)2 → CaCO3 + H2O + CO2

Please note that this reaction does not directly yield HNO2. If you specifically need HNO2, you may need to explore other methods or reactions to obtain it.
