Answer:

2.How is electrochemical energy produced?

- In electrochemistry, electricity can be generated by movements of electrons from one element to another in a reaction known as redox or oxidation-reduction reaction. Electrochemistry is the study of chemical processes that cause electrons to move.

3. What is primary cell?

-A primary cell is a battery that is designed to be used once and discarded, and not recharged with electricity and reused like a secondary cell. In general, the electrochemical reaction occurring in the cell is not reversible, rendering the cell unrechargeable

4. What is secondary cell?

-In contrast to a disposable or primary battery, which is supplied fully charged and discarded after use, a rechargeable battery, storage battery, or secondary cell can be charged, discharged into a load, and recharged many times.

5. What are the different examples of a primary and a secondary cell?

- Primary batteries are “single use” and cannot be recharged. Dry cells and (most) alkaline batteries are examples of primary batteries. The second type is rechargeable and is called a secondary battery. Examples of secondary batteries include nickel-cadmium (NiCd), lead acid, and lithium ion batteries.

Answer:

2. Electrochemical cells either generate electrical energy from chemical reactions or they use electrical energy to cause chemical reactions

3. Primary cells are cells taken directly from living tissue (e.g. biopsy material) and established for growth in vitro.

4. A secondary cell or battery is one that can be electrically recharged after use to their original pre-discharge condition, by passing current through the circuit in the opposite direction to the current during discharge.

5. Primary batteries are “single use” and cannot be recharged. Dry cells and (most) alkaline batteries are examples of primary batteries. The second type is rechargeable and is called a secondary battery. Examples of secondary batteries include nickel-cadmium (NiCd), lead acid, and lithium ion batteries.
