Law of definite proportions

Some basic concepts of chemistry #05

 Law of chemical Combination. 

2. Law of definite or constant proportions : it's states that,

  " The same compound always contains the same elements combined together in the same fixed (definite) proportion by mass and its composition is independent of the method by which it is prepared. "

  To understand this law simply, you have to remember the things that is  -No matter what is  the source of the compound, rather it matter only about the elements of the compound.

yess dude😂😂, there is also limitations of the law of constant proportions.

Limitations:- 

 let's see the  example, ethyl alcohol and dimethyl ether are found to contain the same elements( like carbon, hydrogen,  and oxygen) which are combined in the same mass ratio.

       C2H5-OH  👉👉👉        C:H:O = 12:3:8

       CH3-O-CH3  👉👉👉     C:H:O = 12:3:8

But these two are entirely different compound having different properties. 

    *there  is also many case where the Law of constant proportions fails.
