The following data are obtained when dinitrogen and dioxygen react together to form different compounds: (a) Which law of chemical combination is obeyed by the above experimental data? Give its statement.

Question

Philoid · Accepted Answer

The Law satisfied by the above data is named as Law of Multiple Proportions. This law was given by John Dalton in 1804.

Statement:

When two elements combine to form two or more compounds, then the different masses of one element, which combine with a fixed mass of the other element, bear a simple whole number ratio with another.

Nitrogen and oxygen combine together to form five compounds- Nitrous Oxide [N₂O], Nitric Oxide [NO], Nitrogen Trioxide [N₂O₃], Nitrogen Dioxide [N₂O₄] and Nitrogen pentoxide [N₂O₅]. In these compounds ratio of nitrogen and oxygen by mass is given in the above table.

Thus the ratio of the masses of oxygen which combine with fixed mass of nitrogen are 16:32:48:64:80 that is they are in simple whole number ratio of 1:2:3:4:5.
