Question

1) Burning of coal
2) Burning of Natural gas
3) Respiration
4) Formation of water.
5) Formation of compost.

explain why following reactions are which in nature exothermic Or endothermic​

Answer 1

Explanation:

1) Burning of coal is an exothermic reaction as one of the end product is heat.

2) Burning of natural gas is also an example of exothermic reaction as one of the end products is also heat

3) Respiration is also an exothermic reaction as the end products are H2O+CO2+heat. So heat is present as an end product, it is also an exothermic reaction.

4) Formation of water is neither endothermic nor exothermic.

5)Formation of compost is an endothermic reaction
