Question

Na->NaOH->N a2SO4->BaSO4->BaO->Ba(OH)2->BaCO3->CO2

Answer 1

2Na + 2H2O = 2NaOH + H2

2NaOH + H2SO4 = Na2SO4 + 2H2O

Na2SO4 + Ba(OH)2 = BaSO4 + 2NaOH

2BaSO4 (t=1600°) = 2BaO + 2SO2 + O2

BaO + H2O = Ba(OH)2

Ba(OH)2 + CO2 = BaCO3 + H2O

BaCO3 (t)= BaO + CO2.

Answer 2

It appears that you've provided a sequence of chemical reactions. Let's go through each step:

1. Na → NaOH: This reaction involves the combination of sodium (Na) with water (H2O) to produce sodium hydroxide (NaOH).

2. NaOH → Na2SO4: In this reaction, sodium hydroxide (NaOH) reacts with sulfuric acid (H2SO4) to form sodium sulfate (Na2SO4) and water (H2O).

3. Na2SO4 → BaSO4: This reaction involves the precipitation of barium sulfate (BaSO4) by mixing sodium sulfate (Na2SO4) with barium chloride (BaCl2) or barium nitrate (Ba(NO3)2).

4. BaSO4 → BaO: Barium sulfate (BaSO4) is heated to produce barium oxide (BaO) and sulfur dioxide (SO2) as a byproduct.

5. BaO → Ba(OH)2: Barium oxide (BaO) reacts with water (H2O) to form barium hydroxide (Ba(OH)2).

6. Ba(OH)2 → BaCO3: Barium hydroxide (Ba(OH)2) reacts with carbon dioxide (CO2) to produce barium carbonate (BaCO3) and water (H2O).

7. BaCO3 → CO2: Barium carbonate (BaCO3) can be thermally decomposed to yield carbon dioxide (CO2) and barium oxide (BaO).

Please note that chemical reactions can be subject to various conditions and reactants, and some of the reactions you provided might require specific catalysts or temperatures for them to occur. Additionally, it's essential to handle chemicals with caution and conduct reactions safely in a controlled environment, as some of the reactions involve hazardous materials.
