Respuesta :
Copper(II) oxide reacts with hydrogen.
[tex]CuO + H_2[/tex] → [tex]Cu + H_2O[/tex]
Oxidising agent - [tex]Cuo[/tex]
Reducing agent - [tex]H_2[/tex]
What is a redox reaction?
A chemical reaction that takes place between an oxidizing substance and a reducing substance.
The oxidizing substance loses electrons in the reaction, and the reducing substance gains electrons.
In the reaction [tex]CuO + H_2[/tex] → [tex]Cu + H_2O[/tex]
[tex]Cuo[/tex] is the oxidising agent and [tex]H_2[/tex] is the reducing agent because [tex]Cuo[/tex] is oxidising [tex]H_2[/tex] and [tex]H_2[/tex] is the reducing agent because it is removing oxygen from [tex]Cuo[/tex].
Hence, option B is correct.
