Question

10 example of chemical reactions which happen naturally

Answer 1

10 examples of chemical reactions which happen naturally are as follows:

• Photosynthesis: Photosynthesis is the process by which plants make their own food by using water and carbon dioxide in the presence of sunlight.

The chemical reaction can be written as :

6CO₂ + 6H₂O → C₆H₁₂O₆(aq) + 6O₂ (g)

• Rusting: Rusting is the process in which iron reacts with oxygen in the presence of moisture.

The chemical reaction can be written as :

Fe + 3O₂ + xH₂O → Fe₃O₄ . xH₂O

• Respiration: The process of respiration is also a chemical reaction which can be written as follows:

C₆H₁₂O₆ (aq) + 6O₂ (g) → 6CO₂ (g) + 6H₂O(l) + energy

• Anaerobic Respiration: The reaction can be written as :

C₆H₁₂O₆ → 2C₂H₅OH + 2CO₂

• Combustion: Combustion is the process in which oxidation of a material occurs when it reacts with heat and oxygen.

C + O₂ → CO₂

• Acid-base reactions: The reaction of an acid and base to form salt and water is an acid-base reaction. Such a reaction is a neutralization reaction.

Acid + base → salt + water

• Digestion: The process of digestion includes different chemical reactions through which food is broken down.
• Metathesis:

HC2H3O2(aq) + NaHCO3(aq)  → NaC2H3O2(aq) + H2O() + CO2(g)

• Cooking: The process of cooking is a chemical reaction as which new products are made from the ingredients by using heat.
• Soaps: The soaps form a lather through chemical reactions.
• Batteries: Batteries are an important past of daily life. The function of them is a chemical reaction.
