yes the number of moles is the the number before the substance for example if the equation is balanced and you want to find H2O and it appears like 3H2O in the equation then their are 3 moles of H2O

What determines if a chemical equation is balanced?
If the number of atoms of each element is the same on both sides of the equation, then it is balanced.
An equation is balanced when .?
the number and type of atoms of reactant and product are the same
Equations show each side is equal as far as the number of atoms and molecules?
this is called having a balanced equation .....if both sides are not balanced u must correct it by changing the number of moles
What does a balanced chemical equation convey to a chemist?
A balanced equation indicates the chemical formulas for the substances involved in the reaction and the number of molecules or moles of each substance in the reaction. This enables a chemist to calculate the amount of each reactant needed to produce a desired quantity of product.
As the equation is written which element is not in balance Explain?
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.

When is an equation correctly balanced?
An equation is balanced when the number of each kind of atoms and the total charge of all particles are the same or equal for both the reactants and the products (ie on both sides of the equation).

What is the term for a chemical equation that has the same number of atom on both side?
Balanced equation
What kind of chemical equation has the same number of atoms of each element on each side of the equation?
A "balanced" equation.
Why is the chemical equation 2H2 O2 balanced?
2H2 + O2 ---->2H2O is balanced for the following reasons. Hydrogen and oxygen exist as H2 and O2 and not H and O. The product is water with a formula of H2O. To get balance the number of atoms of reactants and the number of atoms of products must be equal. They are in the balanced equation above. For these reasons the equation is balanced.
How can I tell if a chemical reaction is balanced or not balanced?
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.
When the following equation is balanced using the smallest possible integers what is the number in front of the underlined substance in each case Br2 Kl-l2 KBr?
Br2 + 2KI -> 2KBr +I2
If the number of atoms of each element in the products equals the number of atoms of each element in the reactants the equation is?
In this case, the equation is balanced.
