Question

Statement (1) : Composition and molecular structure of the reactants can be changed by having a chemical change.
BECAUSE
Statement (2) : It is said to be a chemical reaction when new substances and new bonds are formed and old bonds are broken.

• A. (1) is true, (2) is true, (2) is the correct explanation of (1).
  
• B. (1) is false, (2) is true
  
• C. (1) is true, (2) is true

• E. (1) is true, (2) is false

Answer 1

The correct option is A (1) is true, (2) is true, (2) is the correct explanation of (1).

Composition and molecular structure of the reactants can be changed by having a chemical change through which they are converted into products.

In a chemical reaction, new substances and new bonds are formed and old bonds are broken.

Hence, option (A) is the correct answer.
