Answer:
Law of multiple proportion:
This law was put forward by Dalton in 1808. According to this law if two
elements combine to form more than one compound, then the different masses of
one element which combine with a Fixed mass of the other element, bear a simple
ratio to one another.
Hydrogen and oxygen combine to
form two compounds \[{{H}_{2}}O\] (water) and \[{{H}_{2}}{{O}_{2}}\](hydrogen
peroxide).
In water, Hydrogen 2 parts
Oxygen 16 parts In hydrogen peroxide. Hydrogen 2 parts Oxygen 32 parts. The
masses of oxygen which combine with same mass of hydrogen in these two
compounds bear a simple ratio 1 : 2.
Nitrogen forms five stable oxides.
\[{{N}_{2}}O\] Nitrogen 28
parts Oxygen 16 parts
\[{{N}_{2}}{{O}_{2}}\] Nitrogen 28
parts Oxygen 32 parts
\[{{N}_{2}}{{O}_{3}}\] Nitrogen
28 parts Oxygen 48 parts
\[{{N}_{2}}{{O}_{4}}\] Nitrogen
28 parts Oxygen 64 parts
\[{{N}_{2}}{{O}_{5}}\] Nitrogen
28 parts Oxygen 80 parts
The masses of oxygen which
combine with same mass of nitrogen in the five compounds bear a ratio
\[16:\text{ }32\text{ }:48\text{
}:64:\text{ }80\text{ }or\text{ }1\text{ }:\text{ }2\text{ }:\text{ }3\text{
}:\text{ }4\text{ }:\text{ }5.\]
