What are the ways by which a chemical equation can be made more informative ?
by

1 Answer

Answer :

1. The physical state of the reactants and products can be indicated by

putting (s) for solid, (l) for liquid, (g) for gas and (aq) for aqueous state.

2. Evolution or absorption of heat during the reaction can be denoted by

adding or subtracting a heat term on the product side.

3. Temperature, pressure and catalyst can be indicated above the arrow (→

or =) separating the reactants and products.

4. Concentration of reactants and products are indicated by adding word

(dil) for dilute and (cone) for concentrated before their formulae.

5. By the sign → or image information about irreversible and reversible reactions can be obtained.
