Chemical energy is converted into electrical energy in a)dry cell (b) Daniel cell (c) Nicd cell (d)all of these

(d) all of these

Explanation:

Dry cell, Daniel cell and Nickel-cadmium cell are all converting chemical energy into electrical energy.

The answer is all  (D) of the above

Explanation:

a) dry cell- they convert chemical energy into electrical energy thus producing  electricity. They use an electrolyte paste  for materials like zinc with either manganese or carbon to react within the battery and the electrical energy is produced.

b) Daniell cell- it coverts chemical energy into electrical energy by using copper and zinc electrodes dipped in their respective electrolyte. Using electrolysis the energy is converted.

c)NiCd ( Nickel Cadmium) cell- this type of cell is rechargeable and it also converts chemical energy into electrical energy upon discharge during electrolysis and it can also covert electrical energy into chemical energy upon recharge.

neutrons are in the middle of the atom and the electrons, which are much smaller.
