Question

‘Chemistry is the investigation of reactions and use of such reactions (10M)
to form new substances.’ Do you agree with the above statement? Support your answer with reasonable and logical explanation. Explain some of the chemical reactions happening around your surroundings. Give some real examples to clear the concept.

Answer 1

Answer:

Yes, chemistry is the investigation of different reactions and how these reactions can be beneficial or harmful.

Explanation:

• Chemistry can be described as a branch of science in which the chemical composition of elements, molecules or compounds are studied. The new products which are formed by the reaction of these elements, molecules or compounds also are the concerns of the chemistry discipline.

• Hence, the statement is true.

• Some of the chemical reactions occurring in our surroundings are:

1. Respiration: C6H12O6 + 6O2 → 6CO2 + 6H2O

Respiration is the chemical reaction which occurs in every cell of the body of humans in order to provide energy for the normal activity of a cell.

      2. Photosynthesis: 6CO2 + 6H2O → C6H12O6 + 6O2

Photosynthesis is the process by which plants produce energy and release oxygen in the atmosphere which is utilized by other organisms.
