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.

∙ 13y agoIf the number of each element on the reactant side match the number of each element on the product side.
Check all of the atoms on the reactant side and compare them to the product side. If all of the atoms (elements) are equal on both sides, then the equation is balanced. Tada!

∙ 15y agoYou know when a chemical equation is balanced when both sides have the same number of atons. Example: Mg+O2>MgO this changes to 2Mg+O2>2MgO (there is 2 magnesiums on both sides and 2 oxygen. since they are both equal then the equation is balance :)

∙ 11y agoA chemical reaction is always balanced, because chemical reactions follow the laws of conservation of mass and conservation of matter. A chemical equation for the reaction is balanced if and only if the same total numbers of each kind of atomic symbol appear on both the left and right sides of the equation.

Is H2O a chemical reaction?
No, H2O is the compound water and is not a reaction. However, it can be one of the products of a chemical reaction.
Why do chemists balance chemical equations?
being able to write a balanced equation for a reaction is very important. By balancing an equation we can tell how much material we will need to start with, what the likely products to form, and how much of these products will form
An endothermic reaction is one that uses which form of energy?
An endothermic reaction is one that uses chemical energy.
Determine Mole ratios in a balanced chemical equation?
put the coefficient of one substance over the coefficient of the other for example, in the reaction 3H2S + 2Al(OH)3 --> 6H2O + Al2S3 the mole ratio of H2S:H2O is 3:6 or 1/2.
A chemical change of original substance into one or more new substances is called?
Substances that undergo chemical change are called reactants.
How can one tell how much reactant will be used in a reaction?
from a balanced chemical equation
What symbolic representation of a chemical reaction?
There are several things that may symbolize a chemical reaction. One of the main symbols is a chemical equation which will represent the entities in the reaction. .
What does a balanced chemical equation prove?
One or more products containing the same quantity of atoms as the reactants had
Is H2O a chemical reaction?
No, H2O is the compound water and is not a reaction. However, it can be one of the products of a chemical reaction.
Is a chemical reaction?
A chemical reaction is a process that leads to the transformation of one set of chemical substances to another.
What is a balance between products sides and reactants sides of the equation?
A balanced chemical equation is one in which the number of atoms on the product side is equal to the number of atoms on the reactant side. This ensures the law of conservation of mass is upheld, meaning that no atoms are created or destroyed during a chemical reaction.
What is a process that changes one or more new substances?
I think the answer you're looking for is a "Chemical Reaction". For instance, combining Hydrochloric Acid (HCl) and Sodium Hydroxide (NaOH) will cause a Chemical Reaction resulting in salt water (NaCl + H20).
What do you mean by balanced chemical equation?
A balanced chemical equation is one where the number of the same atoms on both sides are equal. A balanced chemial equation is important because during a chemical reaction, there is rearrangement of atoms only and no new atoms are added. To understand the concept of a balanced chemical equation, first consider an unbalanced chemical equation between magnesium and oxygen to form magnesium oxide. Unbalanced chemical equation: Mg(s) + O2(g) --> MgO(s) Initially, this equation is unbalanced because if we count the number of the oxygen atoms on both sides, the number are unequal. There are two oxygen atoms on the left side but only one on the right side. A balanced chemical equation is one where the number of all of the same atoms on both side are equal. We can balance chemical equations by adding numbers to the coefficient of the chemicals that are involved in the reaction. Balanced chemical equation: 2Mg(s) + O2(g) --> 2MgO(s) This equation is now balanced because if we count the number of the same atoms on both side, they are equal. There are two magnesium atoms and two oxygen atoms on both sides of the equation.
What is a stereospecific chemical reaction?
A stereospecific chemical reaction is one that utilizes either the R or the L stereoisomer of a chemical.
Why do chemists balance chemical equations?
being able to write a balanced equation for a reaction is very important. By balancing an equation we can tell how much material we will need to start with, what the likely products to form, and how much of these products will form
Name For Chemicals that are formed in a chemical reaction?
One or more products are formed in a chemical reaction.
An endothermic reaction is one that uses which form of energy?
An endothermic reaction is one that uses chemical energy.
