Which of the following cells produce electrical energy from chemical reactions? l. Lead-acid battery ll. Dry cell III. Deniell cell IV Electrolytic cell

Which of the following cells produce electrical energy from chemical reactions?
l. Lead-acid battery ll. Dry cell III. Deniell cell IV Electrolytic cell

Answer Details

The cells that produce electrical energy from chemical reactions are called electrochemical cells. In an electrochemical cell, a chemical reaction takes place, and the energy released by the reaction is converted into electrical energy. Out of the given options, the lead-acid battery, dry cell, and Daniell cell are all electrochemical cells that produce electrical energy from chemical reactions. The electrolytic cell, on the other hand, is used to drive a non-spontaneous chemical reaction using electrical energy. Therefore, the correct answer is (B) l, ll, and III only.
