Question

Закончите схему записи процесса окисления и востоновления; укажите окислитель и восстановитель: Zn0 ... = Zn+2 Ag+1 ... = Ag0 H0 ... = H+1 Pb+2 ... = Pb0 Na0 ... = Na+1 H+1 ... = H0 Fe+3 ... = Fe0 C0 ... = C+4

Answer 1

Zn⁰ - 2e = Zn²⁺ - восстановитель
Ag¹⁺ + 1e = Ag⁰ - окислитель
H⁰ - 1e = H¹⁺ - восстановитель
Pb²⁺ + 2e = Pb⁰ - окислитель
Na⁰ - 1e = Na¹⁺ - восстановитель
H¹⁺ + 1e = H⁰ - окислитель
Fe³⁺ + 3e = Fe⁰ - окислитель
C⁰ - 4e = C⁴⁺ - восстановитель

Answer 2

Process of Oxidation and Reduction

The given scheme represents a series of reactions involving the oxidation and reduction of different elements. Let's break down the scheme and identify the oxidizing and reducing agents for each reaction:

1. Zn0 → Zn2+ - In this reaction, zinc (Zn) is oxidized from its elemental state (Zn0) to a +2 oxidation state (Zn2+). - The oxidizing agent in this reaction is not explicitly mentioned in the scheme.

2. Ag1+ → Ag0 - In this reaction, silver (Ag) is reduced from a +1 oxidation state (Ag1+) to its elemental state (Ag0). - The reducing agent in this reaction is not explicitly mentioned in the scheme.

3. H0 → H1+ - In this reaction, hydrogen (H) is oxidized from its elemental state (H0) to a +1 oxidation state (H1+). - The oxidizing agent in this reaction is not explicitly mentioned in the scheme.

4. Pb2+ → Pb0 - In this reaction, lead (Pb) is reduced from a +2 oxidation state (Pb2+) to its elemental state (Pb0). - The reducing agent in this reaction is not explicitly mentioned in the scheme.

5. Na0 → Na1+ - In this reaction, sodium (Na) is oxidized from its elemental state (Na0) to a +1 oxidation state (Na1+). - The oxidizing agent in this reaction is not explicitly mentioned in the scheme.

6. H1+ → H0 - In this reaction, hydrogen (H) is reduced from a +1 oxidation state (H1+) to its elemental state (H0). - The reducing agent in this reaction is not explicitly mentioned in the scheme.

7. Fe3+ → Fe0 - In this reaction, iron (Fe) is reduced from a +3 oxidation state (Fe3+) to its elemental state (Fe0). - The reducing agent in this reaction is not explicitly mentioned in the scheme.

8. C0 → C4+ - In this reaction, carbon (C) is oxidized from its elemental state (C0) to a +4 oxidation state (C4+). - The oxidizing agent in this reaction is not explicitly mentioned in the scheme.

Please note that the oxidizing and reducing agents are not explicitly mentioned in the given scheme. It would be helpful to provide additional information or context to determine the specific oxidizing and reducing agents involved in these reactions.
