Identify the term that matches each electrochemistry definition. a. The electrode where reduction occurs
b. An electrochemical cell powered by a spontaneous redox reaction
c. The electrode where oxidation occurs
d. An electrochemical cell that takes in energy to carry out a nonspontaneous redox reaction
e. A chemical equation showing either oxidation or reduction

a. Cathode

b. Galvanic cell

c. Anode

d. Electrolytic cell

e. half reaction

Explanation:

Galvanic cell or Electrochemical cell is defined as a device which is used for the conversion of the chemical energy produced in a spontaneous redox reaction into the electrical energy.

Electrolytic cell is a device where electrical energy is used to drive a non spontaneous chemical reaction.

In the electrochemical cell, the oxidation occurs at an anode which is a negative electrode and the reduction occurs at the cathode which is a positive electrode.  Thus the electrons are produced at anode and travel towards cathode.

The balanced two-half reactions will be:

Oxidation half reaction :

Reduction half reaction :

Thus the overall reaction will be:

samuel de champlain. in 1608, king henry iv sponsored pierre dugua, sieur de mons and samuel de champlain as founders of the city of quebec with 28 men. this was the second permanent french settlement in the colony of canada.

space exploration has led to the development and technological improvement of many everyday items. (if this answer is wrong i will find the right answer) : )
