2 points

a) Zn

b) ZnO

c) H2O

d) H2

e) None of these

​

Answer 1

Answer:

your answer is option d) H²

Answer 2

Explanation:

Which one is reducing agent in given reaction? Zn + H2O → ZnO + H2 

a) Zn ✔

b) ZnO

c) H2O

d) H2

e) None of these

Explaination :-

1. In this reaction, Zn is changing into ZnO. That is, addition of oxygen to Zn. So, we can say that Zn is being oxidised to ZnO.
2. In this reaction, H2O is changing into H2. That is, removal of oxygen from H2O. So, we can say that H2O is being reduced to H2.

Hence,

Oxidised substance = Zn

Reduced substance = H2O

Oxidising agent = H2O

Reducing agent = Zn

Therefore,

Option A is correct.

Additional information :-

Oxidation :-

1. Addition of oxygen
2. Removal of Hydrogen

Reduction :-

1. Addition of Hydrogen
2. Removal of oxygen

Oxidising agent :-

1. The substance which gives oxygen for oxidation is called an oxidising agent.
2. The substance which removes hydrogen is also called an oxidising agent.

Reducing agent :-

1. The substance which gives hydrogen for reduction is called a reducing agent.
2. The substance which removes oxygen is also called a reducing agent.
