Answer 1

СаС2+2Н2О=С2Н2+Са(ОН)2 
С2Н2+Н2=С2Н4

С2Н4 + H2O= C2H5OH

Answer 2

Reaction: CaC2 -> C2H2 -> C2H4 -> C2H5OH

The reaction you mentioned involves the conversion of calcium carbide (CaC2) into various organic compounds, including ethyne (C2H2), ethene (C2H4), and ethanol (C2H5OH). Let's break down the reaction step by step:

1. CaC2 -> C2H2: - The first step of the reaction involves the reaction between calcium carbide (CaC2) and water (H2O). - This reaction produces calcium hydroxide (Ca(OH)2) and ethyne (C2H2). - The balanced chemical equation for this reaction is: CaC2 + 2H2O -> Ca(OH)2 + C2H2.

2. C2H2 -> C2H4: - The second step of the reaction involves the conversion of ethyne (C2H2) into ethene (C2H4). - This conversion can be achieved through various methods, such as catalytic hydrogenation or thermal cracking. - The specific conditions and catalysts used in this step may vary depending on the desired reaction conditions and the specific reaction setup.

3. C2H4 -> C2H5OH: - The final step of the reaction involves the conversion of ethene (C2H4) into ethanol (C2H5OH). - This conversion can be achieved through the process of hydration, where ethene reacts with water in the presence of a catalyst. - The balanced chemical equation for this reaction is: C2H4 + H2O -> C2H5OH.

It's important to note that the reaction you mentioned is a simplified representation, and the actual reaction conditions, catalysts, and specific reaction setups may vary depending on the desired outcome and the specific application.
