Answer 1

Answer:

Respiration is a burning process of food in body to produce energy. Respiration is considered as an exothermic reaction because, in respiration ...  More

Answer 2

Rusting of iron and respiration: (a) both are exothermic processes.

• The chemical process in which energy is released into the surroundings is called an exothermic process.
• The rusting of iron is an exothermic process as energy is released when iron comes in contact with moisture. However, it is a slow process and we do not notice it.
• Respiration is also an exothermic process as a large amount of energy is released due to the breakdown of food molecules.
