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.

pure water does not conduct electricity very well. however, when certain substances are dissolved in water, the solution does conduct electricity. you can make a simple device that shows how well a solution conducts electricity. this device uses a flashlight bulb to indicate how well the solution conducts electricity. the better the solution conducts electricity, the brighter the bulb will glow.
