Question

with example list for information which makes a chemical equation more useful​

Answer 1

Explanation:

Physical state

There are three different states which are solid, liquid and gaseous. If the substance exists in solid state, it is represented by (s).

If the substance exists in aqueous state, it is represented by (aq).

If the substance exists in gaseous state, it is represented by (g).

For example:

Evolution of gas

If the gas is liberated in a reaction, it is indicated by an arrow upward

and its physical state is shown by (g).

For example:

Zn(s) + H2SO4(aq) → ZnSO4(aq) + H2(g)↑

Answer 2

Answer:

Hey there!!

The answer!!:-

To make chemical equations more informative we mention :-

>The state of the reactant and product it is either solid liquid or gas

g for gases

s for solids

l for liquids

aq for aquoas solution.

>If gas we use up arrow sign

and if precipitate we use down arrow sign.

hope this helps!

and if it does mark it as brainliest ☺️
