Question

Складінь рівняння за схемою. СН4 ⇒ С2Н2 ⇒ С2Н4 ⇒ С2Н5Cl ⇒ С2Н5OH ⇒ СН3-COH ⇒ СН3-COOH

Answer 1

Відповідь:

1) 2CH4 = C2H2 + 3H2

2) C2H2 + H2 = C2H4

3) C2H4 + H2O = C2H5OH

4) C2H5OH = H2O + C2H4

Пояснення:

Answer 2

Ответ:

Объяснение:

2СН4 = С2Н2 + 3H2

С2Н2 + H2 = С2Н4

С2Н4 + H2O = С2Н5ОН

С2Н5ОН = СН3СНО + H2

СН3СНО + Ag2O = СН3СООН + Ag

СН3СООН + С2Н5OH = СН3СООС2Н5 + H2O

Answer 3

Balancing the Chemical Equation

To balance the chemical equation based on the given scheme, we need to ensure that the number of atoms of each element is the same on both sides of the equation. Let's go step by step:

1. SN4 (Methane) to C2H2 (Ethyne): The balanced equation for this step is:

CH4 (Methane) → C2H2 (Ethyne)

Explanation: Methane (CH4) is converted to Ethyne (C2H2).

2. C2H2 (Ethyne) to C2H4 (Ethene): The balanced equation for this step is:

C2H2 (Ethyne) → C2H4 (Ethene)

Explanation: Ethyne (C2H2) is converted to Ethene (C2H4).

3. C2H4 (Ethene) to C2H5Cl (Chloroethane): The balanced equation for this step is:

C2H4 (Ethene) → C2H5Cl (Chloroethane)

Explanation: Ethene (C2H4) is converted to Chloroethane (C2H5Cl).

4. C2H5Cl (Chloroethane) to C2H5OH (Ethanol): The balanced equation for this step is:

C2H5Cl (Chloroethane) → C2H5OH (Ethanol)

Explanation: Chloroethane (C2H5Cl) is converted to Ethanol (C2H5OH).

5. C2H5OH (Ethanol) to CH3-COH (Ethanal): The balanced equation for this step is:

C2H5OH (Ethanol) → CH3-COH (Ethanal)

Explanation: Ethanol (C2H5OH) is converted to Ethanal (CH3-COH).

6. CH3-COH (Ethanal) to CH3-COOH (Acetic Acid): The balanced equation for this step is:

CH3-COH (Ethanal) → CH3-COOH (Acetic Acid)

Explanation: Ethanal (CH3-COH) is converted to Acetic Acid (CH3-COOH).

Therefore, the balanced chemical equation based on the given scheme is:

CH4 → C2H2 → C2H4 → C2H5Cl → C2H5OH → CH3-COH → CH3-COOH

Please note that the coefficients in front of each compound may vary depending on the specific reaction conditions.
