Question

Составьте уравнения химических реакций с помощью которых можно осуществить превращения этин — этан — этин — этен — углекислый газ Помогите пожалуйста.

Answer 1

C₂H₂ → C₂H₆ → C₂H₂ → C₂H₄ → CO₂.

1. C₂H₂ + 2H₂ → C₂H₆.
2. C₂H₆ → C₂H₂ + 2H₂.
3. C₂H₂ + H₂ → C₂H₄.
4. C₂H₄ + 3O₂ → 2CO₂ + 2H₂O.

Answer 2

Chemical Reactions for the Transformation of Ethyne to Ethane to Ethene to Carbon Dioxide

To achieve the transformation of ethyne (acetylene) to ethane to ethene to carbon dioxide, we can use a series of chemical reactions. Let's break it down step by step:

1. Transformation of Ethyne to Ethane: - The transformation of ethyne to ethane involves the addition of hydrogen. This is a hydrogenation reaction. - The chemical equation for this reaction is: ``` C2H2 + 2H2 → C2H6 ``` - This reaction is catalyzed by a metal catalyst such as palladium or nickel.

2. Transformation of Ethane to Ethene: - The transformation of ethane to ethene involves the removal of hydrogen. This is a dehydrogenation reaction. - The chemical equation for this reaction is: ``` C2H6 → C2H4 + H2 ``` - This reaction can be achieved through the use of a suitable catalyst, such as alumina or silica-alumina.

3. Transformation of Ethene to Carbon Dioxide: - The transformation of ethene to carbon dioxide involves complete combustion. - The chemical equation for this reaction is: ``` C2H4 + 3O2 → 2CO2 + 2H2O ``` - This reaction is an example of a combustion reaction, where ethene reacts with oxygen to produce carbon dioxide and water.

By sequentially applying these chemical reactions, we can achieve the transformation of ethyne to ethane to ethene to carbon dioxide.
