Question

what happens when hydrogen gas is passed over the heated copper oxide write the chemical equation involved in the reaction​

Answer 1

Answer:

Explanation:

The given reaction is an example of a redox reaction. In such a reaction, if a substance gains oxygen or loses hydrogen, it is said to be oxidized and if a substance loses oxygen or gains hydrogen during the reaction, it is said to be reduced. In the given reaction, hydrogen gains oxygen to form water and copper oxide loses oxygen to form copper.

Hence, H2 is oxidized and CuO is reduced in the given reaction
