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.
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-
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.
What does a two direction arrow mean in a chemical equation?
We usually think of chemical reactions as reactions becoming products. Reality is that products can also become reactants by a reverse reaction. A two-directional arrow indicates that the "forward" and "reverse" reactions exist in a certain balance, or equilibrium.
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.
Where would you find a picture of a double-headed arrow?

What does a two-directional arrow need in a chemical reaction?
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

What is the symmetry of an arrow?
An arrow (→) has one line of symmetry. A double-headed arrow (↔) has two lines of symmetry and rotational symmetry if you want to claim it.
How do you take off double spacing?
go to the top of the page and you will see the B for bold about 8 bouttons to the right there will be a boutton with and arrow pointing up and an arrow pointing down (maybe its blue) click on that and you will be off double space
