Question

hydorogen gas is passed over heated copper oxide Copper and steam are formed write balanced chemical equation with physical state for this reaction state what kind of chemical reaction is this

Answer 1

CuO + H2 →Cu + H2O

Heated Copper [II] oxide + Hydrogen (gas) → Copper metal + Water (gas or steam)

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.
