Question

the reducing agent in the reaction MgO + c ------ Co2 is
​

Answer 1

Explanation:

Mg+CO2→MgO+CO

here oxidation number of Mg changes from 0 to +2 thus it is acting as a reducing agent. Similarly, the oxidation number of C is reduced from +4 to +2. Thus it is acting as an oxidizing agent.

Thus in this reaction, Mg is the reducing agent and CO

2

is the oxidising agent.Also A = MgO and B = CO
