In a galvanic cell .

Options

A. the flow of electrons through a wire is not possible
B. the anode is the positive terminal and the cathode is the negative terminal
C. chemical energy is converted into electrical energy
D. electrical energy is converted into chemical energy

Answer

C

Explanation

Galvanic (or ovltaic) cells are electrochemical cells in which spontaneous redox reactions produce electrical energy . The two halves of the redox reaction are separated, requiring electron transfer to occur through an external circuit. In this way, useful electrical energy is obtained. Everyone is familiar with some galvanic cells. The batteries commoly used in mobile phones, laptops,flashlights, portable radios, photographite equipment, and many toys and appliances are galvanic cells. Automobile batteries consist of voltaic cells connected in series, so their voltage add.
