The following data are obtained when dinitrogen and dioxygen react together to form different compounds.
Mass of dinitrogen | Mass of dioxygen |
14 g | 16 g |
14 g | 32 g |
28 g | 32 g |
28 g | 80 g |
Which law of chemical combination is obeyed by the above experimental data?
Text Solution
Verified by ExpertsC
Law of multiple proportions
Fixing the mass of dinitrogen as 
, the mass of dioxygen combined varies as 16,32 . The reactants are in the ration 
and 
, respectively and forms different compounds.
Similarly other ratio of the reactants are 
in case of fixing mass of 
as 
and varing mass of 
as 
and 
respectively.
Here two elements combine to form more than one compound and the masses of one element that combine with a fixed mass of the other element, are in the ratio of small whole numbers. Thus they follow the law of multiple proportions.
