a. What is the reaction called when oxidation and reduction take place simultaneously? Explain with one example.

verified

When oxidation and reduction takes place simultaneously, the reaction is called redox reaction.
Oxidation: losing of electrons
Reduction: gaining of electrons
Redox Reaction = Reduction + oxidation

Example

$$Cao+H_2 \rightarrow Cu+H_2O$$

In this examples copper oxide is reduced and acts as oxidizing agent and H2 ​ is oxidized and acts as reducing agent.
