Question

what happens when hydrogen gas is added to Copper oxide

Answer 1

When H2 is added to CuO
It gets reduced and water and copper metal is formed.
H2+CuO---------- Cu+H2O

Answer 2

Reaction between hydrogen gas and copper oxide.

Explanation:

• The concept involved is the difference in the reactivity of the elements involved in the reaction.
• In the given case, the reactants involved are hydrogen gas and copper oxide.
• When the reactivity of hydrogen and copper is compared, the former is more reactive than the latter.
• Due to this reason, hydrogen displaces copper from copper oxide and forms two products namely water and copper.
• Due to the formation of copper, a brown color ring appears on top of the reaction mixture.
• The balanced chemical equation involved in the reaction is as follows:

$2H + CuO\rightarrow Cu + H_2O$
