Answer 2

Transformation Chain of NO2, HNO3, H3PO4, Na3PO4

To understand the transformation chain of NO2, HNO3, H3PO4, and Na3PO4, we can follow the chemical reactions involved in their conversions.

1. NO2 to HNO3: - The transformation of NO2 to HNO3 involves a reaction with water and oxygen. - The chemical equation for this reaction is: 2 NO2 + O2 + 2 H2O → 2 HNO3.

2. HNO3 to H3PO4: - The conversion of HNO3 to H3PO4 can be achieved through a reaction with phosphoric acid. - The chemical equation for this reaction is: 3 HNO3 + H3PO4 → 3 H2O + 3 NO2 + H3PO4.

3. H3PO4 to Na3PO4: - The transformation of H3PO4 to Na3PO4 involves a reaction with sodium hydroxide. - The chemical equation for this reaction is: H3PO4 + 3 NaOH → Na3PO4 + 3 H2O.

Therefore, the complete transformation chain is as follows: - NO2 → HNO3 → H3PO4 → Na3PO4
