Everything to the right of the arrow is a product.
The coefficient times the subscripts in a chemical formula show you the number of atoms of each element for each substance in the equation.
Balancing a chemical equation
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 -> H2O2There 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 balancedAnd remember that the arrow is a yield sign in an equation.
All properly balanced chemical equations fit that criteria: they must have the same number of atoms of each element on each side of the "yield" arrow. Balancing an equation can be achieved by using whole number coefficients as needed. This upholds the Law of Conservation of Mass, which states that matter cannot be created or destroyed.

A chemical equation
Balancing a chemical equation
You must have the same number and kinds of atoms on both sides of a chemical equation because of the law of conservation of matter, which states that matter is neither created nor destroyed during a chemical reaction.
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.
The formula of which a compound is made of.Another OpinionA chemical equation represents how many atoms of each element are in one molecule of the substance, for example H2O has 2 Hydrogens and 1 Oxygen per water molecule.
