The arrow is pointing to the other half of the equation. The arrow means "produces".
Another answer:
An arrow which points upwards, generally placed next to one or more of the reaction products indicates a gas.
The arrow points to whatever side the product is on (most of the time you'll see it on the right)
Therefore, in:
2H2 + O2 -> 2H2O
2H2O is the product.
If you were to verbally describe the equation you would say:
"Hydrogen and Oxygen molecules produce water."
Denotes which way the reaction is occuring, i.e reactants ---------> products
A double headed arrow indicates equilibrium, where the reactants are not driven completely to products

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.
It reads as "Yields." The equation is set up as (reactants) (Yield Sign) (Products).
The coefficients in a chemical equation tell how many molecules of that type are reacting. The arrows point in the direction of the reaction. Ex. 2 H + 1 O -> 1 H2O has two hydrogen molecules interacting with one oxygen molecule to form one water molecule.
All is correct.
arrow
The direction and stength of a force can be represented by an arrow. The arrow points in the direction of the force.
the arrow points in the direction of air flow.
to the right
The fuel pump arrow points away from the fuel tank and points toward the engine.
The convention is that reactants are on the left and products are on the right, but the direction of the arrow should also tell you: it points toward the products.
The arrow represents direction and leading. When lost an arrow will point you in the right direction. The recycle sign are arrows formed to make a triangle.

A vector has two properties: magnitude and direction. The representation of a vector is an arrow. The tip of the arrow points to the direction the vector is acting. The length of the arrow represents the magnitude.
A vector is like an arrow. It points in the relevant direction and its length is a measure of the distance.
in most cases it points to the camshaft
it is used for you to find north. the arrow that stays in a direction points north
