What does a formula tell you?
Chemical formulas are used to represent chemical compounds. It shows the component elements of the compound. Also it shows the ratios of the component elements.
What does an empirical formula show?
the empirical formula of a compound tells you the proportions of the elements in the compound. with that information you can make some inferences about the identity of the compound. for example a compound with an empirical formula CH4 tells us that for every carbon atom there are four hydrogen atoms. this means that the compound is methane because no other hydrocarbon can have these roportions (try drawing the lewis structure for C2H8, which doesnt exist. you cant!)
Do you simplify empirical formula ratios?
Yes. An empirical formula is the simplest ratio of the elements in a compound.
Do compounds usually have variable ratios where as mixtures usually have fixed ratios?
No, its the opposite. Compounds have fixed ratios, think of H20, while mixtures can vary. You can make many types of mixtures out of the same things. Because of bonding compounds have fixed ratios.
How does combining elements into a compound affect their properties?
They will either bind on a mollecular scale to form "solutions", or on a non-mollecular scale to form "mechanical mixtures". Certain properties will cause the mixture to combust, give off gasses, or other things, depending on the elements and the ratios.
What shows which elements are in compound and their ratios?
A formula shows constituent elements and their ratios. In the formula Al2O3, you can see aluminum and oxygen bonded in a 2-3 ratio.
What is a symbol that shows the elements in a compound and the ratio of atoms?
You think probable to the chemical formula of a molecule.
What a compound is and how compounds are formed?
Compounds are made by elements bonding together. They are represented by the chemical formula. The chemical formula shows the elements and their ratios in the compound.

What is an abbreviation for elements and their ratios in a compound?
chemical formula
What is a list of Elements in a compound in exact ratios?
the emperical formula
A notion that shows what elements a compound contains and the ratio of the atoms or ions of these elements in the compound?
A chemical formula shows what elements a compound contains, and the ratio of the atoms or ions of the elements in the compound.
What is a composition of a compound shown by?
The chemical formula of the compound. This shows the composition directly in atomic ratios, which can be converted to mass ratios by using the atomic weights of each element in the compound.
Shows the ratio of elements in a compound?
The chemical formula of the compound shows the ratio of the atoms of elements in a compound. This must not be confused with the ratio of their masses.
What is a chemical shorthand that uses symbols to tell what elements are in a compound and their ratios?
Stoichiometry
What forms a compound?
Atoms of elements combine in fixed ratios will form compounds.
