    Chemistry, compounds are defined as any substance that is composed of atoms of two or more elements that are combined in fixed ratios. Compounds can often be reduced in order to separate their elements and study their properties. Compounds such as water (H2O) and Carbon Dioxide (CO2) for example, both contain oxygen and can therefore undergo a process of decomposition that will isolate the elements in order to calculate the quantity of each element and molecule present in the compound. Any compound with
