Question

When hydrogen gas is passed over heated copper 2oxide, copper and steam are formed. Write the balanced chemical equation for this reaction and state the substance oxidized and the substance reduced in the reaction. Identify the type of reaction and define the reaction.

Answer 1

CuO + H2 --------> Cu + H2O

Reaction is already balanced
Oxidized Substance = Hydrogen (From H2 to H2O)
Reduced Substance = Copper (From CuO to Cu)

It is a REDOX REACTION

The reaction in which both oxidation and reduction occurs is called REDOX REACTION

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.
