Question

how can we make equation more informative

Answer 1

by giving the name of state

Answer 2

Heya !!!

This is your answer.

The representation of chemical reaction with the help of symbols and formulas of the substances involved is called chemical equation.

In simple, we use the symbol of the elements.
eg. C + O2 ---> CO2

But this does not provide any information regarding the nature and state of the elements, condition of the reaction, etc.

So, we can make an equation more informative by ....
i). Indicating physical state of the elements.
............... ...........
Solid state is represented by s.
Liquid state is represented by l.
Gaseous state is represented by g.
Aqueous solution is represented by aq.
eg. C (s) + O2 (g) ---> CO2 (g).


By indicating heat changes in the reaction.
................ ........
eg. C (s) + O2 (g) ---> CO2 (g) + Heat.
N2 (g) + O2 (g) + Heat ---> 2NO (g).


By indicating the conditions under which reaction is taking place.
............... .........


Hope it helps
