For example, in the chemical equation for the reaction of water (liquid) breaking into hydrogen (gas) and oxygen (gas) as represented by the balanced chemical equation:

# data[].attributes.body
A balanced chemical equation has the same number of each kind of atom on the reactant side as on the product side. To determine whether a chemical equation is balanced, two numbers are considered: the subscript and the coefficient. A coefficient is the number that comes before the chemical formula and indicates the number of particles that participate in the reaction. The subscript is the number written below the symbol for the element and tells the number of atoms in the element.
In order to determine whether an equation is balanced, one must

multiply the number in front of the chemical formula in the equation (coefficient) by the number written below the symbol for the element(s) (subscript) in the formula. If no coefficient is written, it is understood to be one. For instance, for “2H2O”, there are 4 hydrogen atoms and 2 oxygen atoms. If no subscript is written, it is understood to be 1.
(the 2 behind the H is supposed to be small and written at the bottom)

Determine if the number of each kind of atom on the left side of the arrow is equal to the number of each kind of atom on the right side of the arrow. If it is, then your equation is balanced.

Law of Conservation of Matter states that the amount of matter does not change during a chemical reaction, only that the atoms are rearranged to form new substances. Another interpretation of this law is that matter can neither be created nor destroyed, but can be changed in form. Because matter is neither created nor destroyed, the total mass of the material(s) before the reaction is the same as the total mass of material(s) after the reaction.

Chemical equations are used to represent a chemical reaction. It contains the chemical names or the chemical formulas of the substances that are involved in the reaction. An arrow is used to distinguish between the reactants and the products in the reaction. This arrow can be translated as “yields” or “makes".

# data[].attributes.body
Reactants are substances broken apart or combined in a chemical reaction and are located on the left side of the arrow. Products are new substances formed in a chemical reaction and are located on the right side of the arrow.

Use the picture example below to show you how to balance chemical equations. It needs to be copied in your ISN.
Once you have copied the example, you will need to work on the 3 examples on the board. Follow the steps given in your notes or the PASS Coach Book Lesson 33.
