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.
Its chemical formula.
The ratio depends on the compound.
They are called "formulas" (Latin formulae) and show what elements and ions are in the compound. The formula H2O for water shows that a water molecule is made of two atoms of hydrogen and one of oxygen.The symbols representing chemical compounds are called chemical formulas. They can be expressed as an empirical formulawhich shows the simplest ratio of atoms in the compound, or a molecular formula which shows the actual number of each atom in the compound, or as a structural formula which shows the spatial relationship of the atoms.
The answer depends on the compound.
Proust's law of constant proportions states that a given chemical compound always contains its component elements in fixed ratio (by weight). The ratio does not depend on its source and method of preparation.
A chemical formula shows what elements a compound contains, and the ratio of the atoms or ions of the elements in the compound.
You think probable to the chemical formula of a molecule.
A formula shows constituent elements and their ratios. In the formula Al2O3, you can see aluminum and oxygen bonded in a 2-3 ratio.
The ratio and types of elements in the compound.
The fixed ratio of the elements in a chemical compound is called its RATIO OF MASSES.
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!)
Formula
Example: potassium chloride, KCl Elements in the molecule: potassium and chloride Ratio potassium/chlorine: 1
molecule
Its chemical formula.
The elements present in KI are potassium (K) ad iodine (I). These elements are present in the ratio 1:1
A compound forms whenever 2 or more different elements are chemically bonded.
