Question

CaO-C2H2-C2H4-C2H5OH-C2H5ONa

Answer 1

CaO + 3C = CaC2 + CO

CaC2 + 2H2O = Ca(OH)2 + C2H2

C2H2 + H2 (t,Ni)= C2H4

C2H4 + H2O = C2H5OH

2C2H5OH + 2Na = 2C2H5ONa + H2

Answer 2

The series of chemical reactions you provided represents the conversion of calcium oxide (CaO) to sodium ethoxide (C2H5ONa) via the intermediate compounds acetylene (C2H2), ethylene (C2H4), and ethanol (C2H5OH). Let's go through the reactions step by step:

1. CaO (calcium oxide) reacts with water (H2O) to form calcium hydroxide (Ca(OH)2): CaO + H2O -> Ca(OH)2

2. Calcium hydroxide (Ca(OH)2) reacts with acetylene (C2H2) to form calcium carbide (CaC2) and water (H2O): Ca(OH)2 + 2C2H2 -> CaC2 + 2H2O

3. Calcium carbide (CaC2) reacts with water (H2O) to produce calcium hydroxide (Ca(OH)2) and acetylene gas (C2H2): CaC2 + 2H2O -> Ca(OH)2 + C2H2↑

4. Acetylene (C2H2) undergoes a reaction known as "hydration" to form ethylene (C2H4): C2H2 + H2O -> C2H4

5. Ethylene (C2H4) undergoes a reaction known as "oxidation" to form ethanol (C2H5OH): C2H4 + O2 -> C2H5OH

6. Ethanol (C2H5OH) reacts with sodium hydroxide (NaOH) to produce sodium ethoxide (C2H5ONa) and water (H2O): C2H5OH + NaOH -> C2H5ONa + H2O

So, the overall reaction can be summarized as:

CaO + 2H2O + 2C2H2 + O2 + NaOH -> C2H5ONa + 3H2O + Ca(OH)2

Please note that the specific reaction conditions and catalysts may vary depending on the desired outcome and reaction parameters.
