Question

Give 3 examples each of endothermic and exothermic reactions. (Note:- Make sure they are chemical reactions!)

Answer 1

Answer:

endothermic- 1. melting ice cubes

2. melting solid salts

3. evaporating liquid water

4. converting frost to water

exothermic-

1. combustion

2. detonation of nitroglycerin

3. nuclear fission of uranium-235

4.neutralization reactions

Answer 2

This topic explains the difference between Endothermic and Exothermic Reactions. There are a number of chemical reactions in Chemistry and they are divided into many sub and main reactions. Similar is the case with the endothermic and exothermic reactions in Chemistry. These release energy in the form of sound, light, cold or heat.

Explanation:

In simple terms, the endothermic reactions absorb energy from the surrounding that is in the form of heat. On the other hand, an exothermic reaction releases energy into the surrounding of the system.

A popular example of an endothermic chemical reaction is photosynthesis. During this process, plants absorb energy from the Sun and convert it into carbon dioxide and water into glucose and oxygen. An example of an exothermic reaction is the chemical reaction between sodium and chlorine, which results in the formation of sodium chloride (also known as common salt)
