Question

Cu + H₂O → CuO + H₂ This equation shows that Cu is . This equation shows that H₂ is .

Answer 1

Cu is oxidized and H₂ is reduced.

Step-by-step explanation:

Given chemical equation,

`$Cu + H_(2)O \to CuO + H_(2)$`

On observing the equation, if we write the oxidation states of all elements in the compounds, we will get

`$Cu^(0) + H_(2)^(+1)O^(-2) \to Cu^(+2)O^(-2) + H_(2)^(0)$`

In this equation,

Oxidation number of 'Cu' is increased from 0 to 2. Hence it is oxidized. While the oxidation number of 'H₂' is decreased from +1 to 0. Hence it is reduced.
