Chain of Transformations and Chemical Reactions

To solve the given chain of transformations and determine the types of chemical reactions involved, we will break down the process step by step.

A) C → CO2 → H2CO3 → Na2CO3 → H2CO3

1. Genetic series of barium nitrate (Ba(NO3)2): - Barium nitrate (Ba(NO3)2) is an inorganic compound composed of the barium cation (Ba2+) and the nitrate anion (NO3-). It is commonly used in fireworks and pyrotechnics as an oxidizer. - The genetic series of barium nitrate involves the decomposition of barium nitrate into barium oxide (BaO), nitrogen dioxide (NO2), and oxygen (O2) when heated. The reaction can be represented as follows: ``` 2 Ba(NO3)2(s) → 2 BaO(s) + 4 NO2(g) + O2(g) ```

2. Equations for the reactions and their types: a) C → CO2 (Combustion reaction) - Carbon (C) reacts with oxygen (O2) to form carbon dioxide (CO2) in a combustion reaction. - The balanced equation for this reaction is: ``` C(s) + O2(g) → CO2(g) ```

b) CO2 → H2CO3 (Acid-base reaction) - Carbon dioxide (CO2) dissolves in water (H2O) to form carbonic acid (H2CO3). - The balanced equation for this reaction is: ``` CO2(g) + H2O(l) → H2CO3(aq) ```

c) H2CO3 → Na2CO3 (Neutralization reaction) - Carbonic acid (H2CO3) reacts with sodium hydroxide (NaOH) to form sodium carbonate (Na2CO3) and water (H2O). - The balanced equation for this reaction is: ``` H2CO3(aq) + 2 NaOH(aq) → Na2CO3(aq) + 2 H2O(l) ```

d) Na2CO3 → H2CO3 (Neutralization reaction) - Sodium carbonate (Na2CO3) reacts with hydrochloric acid (HCl) to form carbonic acid (H2CO3), sodium chloride (NaCl), and water (H2O). - The balanced equation for this reaction is: ``` Na2CO3(aq) + 2 HCl(aq) → H2CO3(aq) + 2 NaCl(aq) ```

Please note that the given chain of transformations involves multiple chemical reactions of different types, including combustion, acid-base, and neutralization reactions.
