what is multiple proportion and what is reciprocal proportion? please explain it briefly with examples
Answers
here is your answer
The law of reciprocal proportions states that, "If two different elements combine separately with a fixed mass of a third element, the ratio of the masses in which they do so are either the same as or a simple multiple of the ratio of the masses in which they combine with each other".
Although this law may seem complicated, it is fairly easy to understand with an example.
For example, 3 g of
C
react with 1 g of
H
to form methane.
Also, 8 g of
O
react with 1 g of
H
to form water.
The mass ratio of
C:O
=
3
:
8
.
In the same way, 12 g of
C
react with 32 g of
O
to form
CO
2
.
The mass ratio of
C:O = 12:32 = 3:8
.
The mass ratio in which
C
and
O
combine with each other is the same as the mass ratio in which they separately combine with a fixed mass of
H
.
Similarly, 12 g of
C
react with 16 g of
O
to form
CO
.
Here, the mass ratio of
C:O = 12:16 = 3:4
.
The mass ratio in which they separately react with a fixed mass of
H
is 3:8.
The ratio of the two ratios is
3
/
4
3
/
8
=
8
4
=
2
1
.
Here, the ratio in which
C
and
O
combine with each other is twice the ratio in which they separately combine with a fixed mass of
H
The alimentary canal is mainly referred to as the pathway by which food enters our body and moves out through the anus after digestion. It is a tube-like structure which starts from the mouth and ends in the anus.
