Question

What are the different ways can make more informative about the chemical reaction?

Answer 1

Answer:

The various ways in which a chemical equation can be made more informative are : (i) By indicating the physical states of the reactants and products. Example: Gaseous state is indicated by the symbol (g). (ii) By indicating the heat changes taking place in the reaction.

The various ways in which a chemical equation can be made more informative are:

(i) By indicating the physical states of the reactants and products. Example: Gaseous state is indicated by the symbol (g).

Zn(s)+H2SO4(aq)→ZnSO4(aq)+H2(g) 

(ii) By indicating the heat changes taking place in the reaction. For example: An exothermic reaction is indicated by writing "Heat" or "Heat energy" or "Energy" on the products side of an equation. 

C(s)+O2(g)→CO2(g)+Heat
