In an empirical formula, at least one of the element symbols must have a subscript (possibly including the implicit subscript "1" that is presumed when there is no explicit subscript) that is a Prime number. The subscripts in a chemical formula must correspond to the actual number of atoms of each element present in a molecule or formula unit of the compound and therefore may be any integral multiple of the subscripts in the empirical unit. For example, the empirical formula of both acetylene (also called "ethyne") and benzene is CH, but the chemical formulas are C2H2 for acetylene and C6H6 for benzene.

The empirical formula uses as subscripts the lowest whole number ratio of atoms combined in the substance. Many ionic substances do not have a molecular formula because they form a crystal lattice and not individual molecules. Molecular compounds may have both. The molecular formula shows the actual number of combined atoms in a single molecule.

Different chemical formulas represent different chemical substances.


"Molecular formulas show the total number of each atom in the molecule. Empirical formulas only show the ratio of the elements in the molecule. For example - acetate Molecular Formula Empirical Formula C6H12O6 CH2O " I just wanted to note that although this is correct the chemical formula in the example "C6H12O6" is not acetate. It is glucose. Acetate is a derivative of acetic acid.


Empirical formulas show the simplest whole number ratio of these atoms. Molecular formulas show the actual ratio of atoms in the compound. For example: Glucose is the a simple sugar whose molecular formula is C6H12O6 Its empirical formula would be CH2O which would be its molecular formula divided by the smallest whole number. Chemical Name Hydrogen peroxide Empirical Formula HO Molecular Formula H2O2 chemical name Benzene empirical formula CH molecular formula C6H6 remember that several compounds can have the same empirical formula


The similarity Is that you can find the components of the compound from both formulas

It is a chemical change because it is a change of color. And because is a difference between formulas: CoCl2 is blue and CoCl2.2H2O is purple.


empirical probability is when you actually experiment with it and get data values, and theoretical probability is when you use math to make an educated guess.

The empirical formula has the smallest whole number for their subscript whereas the molecular formula is the actual number of molecules or atoms in a compound.



the difference between a physical change and a chemical change is that a physical change is usually reversible whilst a chemical change is not reversible.


A formula unit includes the correct number of each kind of atoms present in a molecule of a covalently bonded compound, but an empirical formula does not necessarily do so. An empirical formula is reliable with respect to the ratios between each kind of atom, but the molecule may contain any positive integral number of empirical formulas, including one.
