In the word equation, which of the following is/are not indicated?

• A. Reactants in words
• B. Formulae of reactants in chemical reactions and equation
• C. Products in words
• D. The physical state of chemicals

Answer 1

The correct option is B

Formulae of reactants in chemical reactions and equation

Word equation for a chemical reaction:

• It is a chemical reaction expressed in words rather than chemical formulas.
• For example, carbon burns with oxygen to form carbon dioxide.

Carbon + Oxygen $\to$Carbon dioxide

The correct option is (B):

• Formulae of reactants are not mentioned in the word equation.

The explanation for incorrect options:

(A) In the word equation, reactants are written in words. So, option (A) is incorrect.

(C) In the word equation, products are written in words. So, option (C) is incorrect.

(D) The physical states of chemicals can be mentioned in the word equation.

Hence, the correct option is (B), The formulae of reactants are not indicated in the word equation.
