Question

When hydrogen gas is passed over heated copper2 oxide ?Cooper and steam are form write the balance chemical equation with physical state for this reaction state what kind of chemical reaction is this?

Answer 1

CuO(s) + H2(g) gives out Cu(s) + H2O(l)

Redox reaction, as CuO is reduced to Cu and H2 is oxidised to H2O

Answer 2

Answer:

CuO(s)+H2(g) --> Cu(s)+H2O(g)

Explanation:

it is a kind of redox /displacement reaction as H2 displaces CuO to form Cu and H2O. also hydrogen gas reduces the compound. here H2 is reducing agent and substance reduced is CuO.
