Question

 Explain the following in term Reduction of gain or loss of oxygen with two example.

Answer 1

Reduction Reaction: It is a chemical reaction in which loss of oxygen or gain of hydrogen takes place

1)CuO+H2 `"heat"/`>Cu+H2O

Here, Copper Oxide is reduced to become Copper

2)ZnO+C `"heat"/`>Zn+CO

Here, Zinc Oxide is reduced to become Zinc

Answer 2

In a chemical reaction, when the oxygen is being removed from the compound then it is said to be reduced. Example:

CuO(s)+H₂(g)→Cu(s)+H₂O(l) 2HgO→2Hg+O₂
