Question

give me examples of chemical reactions that takes place in our daily life with types?

Answer 1

Dear Student,

Some chemical reaction in our daily life:

• Rusting of iron objects left exposed to humid atmosphere – redox reaction

The chemical equation of rusting of Iron is :

4 Fe + 3 O ₂ + 2x H ₂ O → 2 Fe ₂ O ₃ .xH ₂ O

• Souring of milk- fermentation (decomposition reaction)
• Photosynthesis : The reaction is given below :

6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂

• Digestion of food - decomposition reaction
• Respiration – Exothermic reaction

The chemical reaction for aerobic cellular respiration is:

C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O + Energy

It is an exothermic reaction because enerrgy in the form of heat is given out.

• Marble statues attacked by acid rain- displacement reaction

Marble stone majorly contains Calcium carbonate, which reacts with the acid rain water as follows:

CaCO₃ + H₂SO₄ --------> CaSO₄ + H₂O + CO₂

Thus the marble statues are damaged.
