Chain of Transformations:

The given chain of transformations is as follows: N2 -> N2O5 -> HNO3 -> Ba(NO3)2 -> Na2O -> NaOH -> Na2S -> NaNO3.

Let's break down each transformation step by step:

1. N2 to N2O5: - Nitrogen gas (N2) reacts with oxygen gas (O2) to form nitrogen pentoxide (N2O5). - The balanced chemical equation for this reaction is: N2 + 5O2 -> 2N2O5.

2. N2O5 to HNO3: - Nitrogen pentoxide (N2O5) reacts with water (H2O) to form nitric acid (HNO3). - The balanced chemical equation for this reaction is: N2O5 + H2O -> 2HNO3.

3. HNO3 to Ba(NO3)2: - Nitric acid (HNO3) reacts with barium hydroxide (Ba(OH)2) to form barium nitrate (Ba(NO3)2) and water (H2O). - The balanced chemical equation for this reaction is: 2HNO3 + Ba(OH)2 -> Ba(NO3)2 + 2H2O.

4. Ba(NO3)2 to Na2O: - Barium nitrate (Ba(NO3)2) reacts with sodium sulfate (Na2SO4) to form barium sulfate (BaSO4) and sodium nitrate (NaNO3). - The balanced chemical equation for this reaction is: Ba(NO3)2 + Na2SO4 -> BaSO4 + 2NaNO3.

5. Na2O to NaOH: - Sodium oxide (Na2O) reacts with water (H2O) to form sodium hydroxide (NaOH). - The balanced chemical equation for this reaction is: Na2O + H2O -> 2NaOH.

6. NaOH to Na2S: - Sodium hydroxide (NaOH) reacts with hydrogen sulfide (H2S) to form sodium sulfide (Na2S) and water (H2O). - The balanced chemical equation for this reaction is: 2NaOH + H2S -> Na2S + 2H2O.

7. Na2S to NaNO3: - Sodium sulfide (Na2S) reacts with nitric acid (HNO3) to form sodium nitrate (NaNO3) and hydrogen sulfide (H2S). - The balanced chemical equation for this reaction is: Na2S + 2HNO3 -> 2NaNO3 + H2S.

Please note that the given chain of transformations involves various chemical reactions, and the balanced chemical equations provided above represent those reactions.
