(i) CuO(s) + H2(g) - → Cu(s) + H2O(g)
(ii) CuO(s) + Zn(s) → ZnO(s) + Cu
(b) State one industrial application of reduction.​

Answer 1

i ka reactant ka h2 hoga

ii ka zn hoga

Answer 2

Answer:

(a) i) since CuO loses oxygen it is being reduced.

since H2 is gaining oxygen it is being oxidised.

ii) since CuO loses oxygen it is being reduced.

since Zn is gaining oxygen it is being oxidized.

(b) Reduction process is used to extract metals from their ores.
