If it is balanced then the mass (amount) of elements on each side of the arrow will be equal.
count the number of molecules of each element on each side of the equation. they need to all be equal.
An example:
H2 + O2 -> H2O2
There are two H's on the left hand side and two on the right hand side, so the H's are balanced.
The same is for the O's.
==> The equation is balanced
And remember that the arrow is a yield sign in an equation.

How can one determine the initial concentration of a substance in a chemical reaction?
To determine the initial concentration of a substance in a chemical reaction, you can use the formula: initial concentration (final concentration) / (reaction coefficient). This involves knowing the final concentration of the substance and the reaction coefficient from the balanced chemical equation.
What is the coefficient does Zn have in the balanced equation?
In the balanced chemical equation representing the reaction involving Zn, the coefficient for Zn is typically 1. This means that one molecule of Zn is involved in the reaction as written.
What information in a balanced chemical equation shows how many miles of a reactant are involved in the reaction?
A balanced chemical equation does not provide information on the physical amount or quantity of reactants involved in a reaction, such as miles. The coefficients in a balanced chemical equation represent the mole ratio of reactants and products, not physical quantities like miles. To determine how many moles or amount of reactant is involved in a reaction, one would need to use stoichiometry calculations based on the coefficients in the balanced equation and known quantities.
What is a scientific reaction?
A scientific reaction is a process in which one or more substances are changed into one or more new substances through the breaking and forming of chemical bonds. These reactions follow the laws of physics and chemistry and can be described by balanced chemical equations.

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.
