Yes.
The arrow is an indication for the sense of reaction.
An equation written may or may not be balanced. It is balanced if the number of elements on both sides of the arrow, that is before and after the reaction, is equal. Sometimes the number of elements is not the same on both sides of the arrow, then we need to balance the equation. This is done in accordance to the law of conservation of mass which states that the mass of a substance does not get destroyed or created due to a chemical reaction.
Above the valence arrow.
Draw the cyclopentene + H2. Draw the arrow(on top of the arrow type Pd). The result is a cyclopentane (not cyclopentene) For the reaction of Cyclopentene with Br is: Draw the cyclopentene + Br. Draw the arrow; the reaction is 1,2-bromocyclopentane.

The arrow represents 'yields' as in "CH4 + 2O2 yields CO2 + 2H2O"
The arrow is read as "produces" or "yields."

The balanced equation is: CH4 + 2 O2 → CO2 + 2 H2O
The chemicals on the left side of the arrow are the reactants and the chemicals on the right side of the arrow are the products.
If the equation has the same number of each type of atom on both sides of the arrow, it is balanced. If the number of atoms on each side of the arrow is not the same, the equation is not balanced. For example, in the equation H2 + O2 -->H2O, there are two hydrogen atoms and two oxygen atoms on the left, and two hydrogen atoms and one oxygen atom on the right. Therefore, the equation is not balanced. However, in the equation 2H2 + O2 -->2H2O, there are four hydrogen atoms and two oxygen atoms on the left and four hydrogen atoms and two oxygen atoms on the right, so the equation is balanced.
balanced
