Question

Define law of multiple or reciprocal proportion

Answer 1

The law of reciprocal proportions was proposed by Jeremias Ritcher in 1792. It states that, "If two different elements combine separately with the same weight of a third element, the ratio of the masses in which they do so are either the same or a simple multiple of the mass ratio in which they combine.

Answer 2

$\huge\mathfrak\red{Answer :}$


$\huge\textbf{Law of Multiple Proportion :}$


When fixed mass of an element react with different amount of another same element then it bears a simple whole number ratio..
======================================

$\huge\textbf{Example :}$

$C$ + $\dfrac{1}{2}O_{2}$ ---> $CO$

Here,

$C$ = 12 gm

$\dfrac{1}{2}O_{2}$ = 16 gm

* $C$ + $O_{2}$ ---> $CO_{2}$

$C$ = 12 gm

$O_{2}$ = 32 gm

→ Ratio of $\dfrac{1}{2}O_{2}$ : $O_{2}$

= 16 : 32

= 1 : 2

======================================


$\huge\textbf{Law of Reciprocal Proportion :}$


It states that when fixed mass of an element react with different amount of another different element then it bears a simple whole number ratio...
======================================

$\huge\textbf{Examples :}$

1) $C\:+\:2H_{2}$ ----> $CH_{4}$

Here; 

$C$ = 12 gm

$H_{2}$ = 4 gm

* $C\:+\:O_{2}$ ----> $CO_{2}$

Here;

[tex}C\: = \:12 \:gm[/tex]

$O_{2}$ = 32 gm

→ Ratio of $2H_{2}\::O_{2}$

= 4 : 32

= 1 : 8

====================================
