Question

Write a redox reaction and label r for reduction and o for oxidation​

Answer 1

Answer:

a redox reaction is a reaction in which oxidation and reduction takes place simultaneously.

Explanation:

For example :

Cuo + H2 →H2O (o) + Cu (r) ( these are not physical sates of compounds or elements).. here o is for denoting oxidation and r is for denoting reduction...

Here, Cuo has been reduced to Cu (removal of oxygen). And H2 has been oxidised (addition of oxygen). it was in terms of oxygen and hydrogen.. The element which is getting oxidised is reducing agent and the element or compound which is getting reduced is oxidising agent..

I hope it helps you....

Answer 2

Answer:

Redox reaction ex. :-

1. Na + Cl2 ---- 2NaCl

Explanation:

So, here Na is oxidised ( add. of non-metal )

Cl is reduced ( add. of metal is called reduction )
