Chemical formulas are used by the scientific society in order to help them organise their data. There are three dofferent types of chemical formulas and they are listed below:
 
Empirical Model: Based only on data, used to provide an educated guess, not an explanation of a system. Consists of functions based on data collected.
 
Molecular Model: Model in which only elements and their quantities are represented
 
Structural Model: Shows types and quantity of atoms in a molecule and the arrangement of the bonds in the molecule.
 
 
 

Chemical equations are symbolic representations of a chemical reactions. they consist of two sides. On the left, there are the reactants [substances mixed to cause chemical change] and on the right, there are the products [substance created from mixing the two or more reactants.]
 
Word equations are chemical equations where the full name of each substance is written.

IMPORTANT VOCAB YOU WANNA KNOW:
 
Subscript: Number in a chemical formula that tells how many atoms of a particular element are in the compound.
 
Coefficient: Number that placed in front of a symbol or a compound formula in a chemical equation that indicates how many atoms or molecules of that substance are involved in the chemical reaction.
