How Are The Chemical Formula And Name

Today we often use chemical formulas such as NaCl C 12 H 22 O 11 and CoNH 3 6 ClO 4 3 to describe chemical compoundsBut we still need unique names that unambiguously identify each compound. Long before chemists knew the formulas for chemical compounds they developed a system of nomenclature that gave each compound a unique name.
