Answer 1

O-восстановитель, Н2-окислитель, Сu(заряд 0,2+)-окислители

Answer 2

Chemical Reaction Analysis

The given chemical reaction is: CuO + H2 = Cu + H2O.

1. Identifying Oxidation States: - The oxidation states of the elements involved in the reaction are: - H2 (charge 0) - Cu (charge 0) - O (charge -2) - Cu (charge +2).

2. Identifying the Reducing Agent and Oxidizing Agent: - The substance that causes another substance to be reduced and is itself oxidized is called the oxidizing agent. - The substance that causes another substance to be oxidized and is itself reduced is called the reducing agent.

3. Determining the Reducing Agent and Oxidizing Agent: - In the given reaction, CuO is being reduced to Cu, while H2 is being oxidized to H2O. - Therefore, in this reaction, CuO is the oxidizing agent and H2 is the reducing agent.

This analysis identifies CuO as the oxidizing agent and H2 as the reducing agent in the given chemical reaction.
