Why do you use a double arrow to show the dissociation of a weak acid or weak base in aqueous solution?

Double arrow means reversible reaction while single arrow represents complete reaction.For strong acid such as HCl,they undergo ionization to form H+ and Cl-.For weak acid such as H2CO3,it undergoes reversible reaction.
H2CO3->H+ + HCO3-
HCO3- <->H+ + CO3 2-

Why is only one arrow required for the dissociation of a strong acid?
because the reaction of dissociation is At any one time virtually 100%
What abbreviation of the physical state for a precipitation reaction?
The common abbreviations for state are (s) for solid, (g) for gas, (l) for liquid, and (aq) for aqueous solution. Of these, (aq) and (s) are likely to be the important ones for precipitation. Sometimes a down arrow is used to emphasize that a precipitate is formed.
Why do some chemical equations use double arrows while some do not?
A double arrow shows that the reaction is reversible, it represents an equilibrium in which the products on the right can react together and produce the left hand side. A chemical equation without a double arrow isn't reversible and can only go in one direction.
In a chemical equation weak acids and weak bases are usually recognizable by the?
double arrow
What does a double arrow mean in a chemical reaction?
Equilibrium, where the rate of the forward reaction is equal to the rate of the reverse reaction.
Why is only one arrow required for the dissociation of a strong acid?

How many parallel sides are in a double arrow?
This depends on how the double arrow is drawn. Most of the lines if not all will be parallel.

What is a double down arrow?
An arrow is a graphical symbol used to point or indicate direction.
What does H20 above arrow in a chemical formula mean?
This means that the reaction in question takes place in an aqueous solution. Even when water does not take part in a reaction, many things - most things, actually - will be more chemically active if dissolved in water, than in solid form.
What abbreviation of the physical state for a precipitation reaction?
The common abbreviations for state are (s) for solid, (g) for gas, (l) for liquid, and (aq) for aqueous solution. Of these, (aq) and (s) are likely to be the important ones for precipitation. Sometimes a down arrow is used to emphasize that a precipitate is formed.
