Question

6. Напишіть рівняння реакцій, що лежать в основі схем. Вкажіть умови їх проходження. С2Н6 → С2Н5Сl → C4H10 → CO2 → CaCO3

Answer 1

Ответ:

Объяснение:

CH3-CH3 + Cl2 -> CH3-CH2Cl + HCl     (hy)

CH3-CH2Cl + 2Na + ClCH2-CH3 -> CH3-CH2-CH2-CH3 + 2NaCl

2C4H10 + 13O2 = 8CO2 + 10H2O

CO2 + CaO =CaCO3

Answer 2

Equations and Conditions for the Given Reactions

The reactions provided in the question are as follows:

1. C2H6 → C2H5Cl 2. C2H5Cl → C4H10 3. C4H10 → CO2 4. CO2 → CaCO3

Let's break down each reaction and discuss the conditions under which they occur.

1. C2H6 → C2H5Cl: - This reaction involves the conversion of ethane (C2H6) to ethyl chloride (C2H5Cl). - The reaction is an example of a substitution reaction, where a chlorine atom replaces a hydrogen atom in the ethane molecule. - The reaction typically requires the presence of a catalyst, such as aluminum chloride (AlCl3) or hydrogen chloride (HCl). - The reaction can occur under normal temperature and pressure conditions.

2. C2H5Cl → C4H10: - This reaction involves the conversion of ethyl chloride (C2H5Cl) to butane (C4H10). - The reaction is an example of a dehydrohalogenation reaction, where a hydrogen halide (in this case, hydrogen chloride) is eliminated from the molecule, resulting in the formation of a double bond. - The reaction typically requires the presence of a strong base, such as sodium hydroxide (NaOH) or potassium hydroxide (KOH). - The reaction can occur under normal temperature and pressure conditions.

3. C4H10 → CO2: - This reaction involves the combustion of butane (C4H10) to produce carbon dioxide (CO2) and water (H2O). - The reaction is an example of a combustion reaction, where a hydrocarbon reacts with oxygen to produce carbon dioxide and water. - The reaction requires the presence of oxygen (O2) as the oxidizing agent. - The reaction typically occurs at high temperatures and in the presence of a flame or spark.

4. CO2 → CaCO3: - This reaction involves the conversion of carbon dioxide (CO2) to calcium carbonate (CaCO3). - The reaction is an example of a precipitation reaction, where a solid product (calcium carbonate) is formed from the reaction of two aqueous solutions (carbon dioxide and calcium hydroxide). - The reaction typically requires the presence of calcium hydroxide (Ca(OH)2) as the reactant. - The reaction can occur under normal temperature and pressure conditions.

Please note that the conditions mentioned above are general conditions for these types of reactions. Actual reaction conditions may vary depending on the specific reaction conditions, such as temperature, pressure, catalysts, and reactant concentrations used in the laboratory or industrial settings.
