Balance the following redox equation, identifying the element oxidized and the element reduced. show all work to solve the problem. cr2o7 2- + c2h5oh --> cr3 + co2

Explanation:

A redox equation is defined as an equation that shows reduction and oxidation are taking place simultaneously in a chemical reaction.

When electrons are lost in a chemical reaction then it is known as oxidation reaction. Whereas when electrons are gained in a chemical reaction then it is known as a redox reaction.

For example,

Reduction-half reaction:

Oxidation state of Cr in is +6.

Oxidation-half reaction:

Oxidation state of C in is -2 and in oxidation state of C is +4.

Now, to balance the equation multiply reduction-half reaction by 2.

Thus, the combined balanced chemical reaction equation will be as follows.
