Question

write any five advantages and disadvantages of chemical equation for class 10​

Answer 1

Answer:

The advantages of writing a chemical equation using formulae and symbols are:

(i) The representation of a chemical reaction becomes easy. It saves time and space in writing.

(ii) In order to prepare a definite amount of the product, the amount of the reactant to be used can be calculated accurately.

(iii) A single arrow between the reactants and products tells us that the reaction goes to completion while a double arrow shows that it is a reversible reaction

Disadvantage:-

(i) A chemical equation does not tell us the

physical state of the reactants and the products in the reaction.

(ii) It does not tell us the actual concentration or dilution of the reactants used in the reaction.

(iii) It does not tell whether the reaction starts at its own or some heat is required to start the reaction.

(iv) It does not tell whether the reaction is violent in nature or not.

(v) The time taken by the reaction to complete itself is also not known.
