Question

Помогите решить задачу, очень нужноКакой объем этана потребуется (н.у) для получения дихлорэтана, если его выходравен 80%.

Answer 1

Задачу надо решать вот по этим уравнениям:
С2Н6 = С2Н4 + Н2
С2Н4 + Cl2 = C2H4Cl2

Answer 2

Calculating the Volume of Ethane Required to Produce Dichloroethane

To calculate the volume of ethane required to produce dichloroethane, we can use the stoichiometry of the reaction and the given yield.

Given: - Yield of the reaction = 80%

The balanced chemical equation for the reaction is: ``` C2H6 + Cl2 → C2H4Cl2 + HCl ```

Using the stoichiometry of the reaction, we can calculate the volume of ethane required.

Calculation Steps:

1. Molar Ratio: - From the balanced chemical equation, the molar ratio of ethane to dichloroethane is 1:1.

2. Using the Yield: - Since the yield of the reaction is 80%, we need to account for this in the calculation.

3. Calculation: - We can use the molar volume of a gas at standard temperature and pressure (STP) to convert the moles of ethane to volume.

Conclusion:

The volume of ethane required to produce dichloroethane can be calculated using the molar ratio and the given yield of the reaction.
