Question

Identify the substance oxides are the substance reduced in the following reaction
(a) 4na (s)+ o2 (s) =2na o(s) (b) I cup (s) + H2(g)=cu(s)+h20(l)

Answer 1

hlo mate

here is your answer

In the reaction

CuO (s) + H2 (g) → Cu(s) + H2O (g)

a) Name the oxidized substance.

Oxidation means addition of oxygen .

So In the given reaction, Hydrogen is oxidized.

b)Name the reduced substance.

Reduction means removal of oxygen .

So the substances getting reduced is CuO.
