Write the molecular formula in the column next to the structural formula of each compound. A chemical nomenclature is a set of rules to generated systematic names for chemical compoundsThe nomenclature used most frequently worldwide is the one created and developed by the International Union of Pure and Applied Chemistry IUPAC. For example water H2O is a compound consisting of two hydrogen atoms bonded to an oxygen atom.
Its a low-molecular weight compound which means its highly volatile and flammable making it ideally suited for the production of gasoline.
For example the molecular formula of ethane is C 2 H 6. For example chemical formula of aluminium sulphate is written as Al 2 SO4 3 and that of calcium phosphate as Ca 3 PO 4 2. For example here is how the method of crossing over can be used to determine the chemical formula for aluminum oxide. Writing a formula for ionic compounds containing polyatomic ions also involves the same steps as for a binary ionic compound.
