Question

Examples of reciprocal proportion

Answer 1

✔️✔️The law of reciprocal proportion states that:-

When 2 different elements separately combine with a fixed mass of a 3rd element, the proportion in which they combine with 1 another shall be either in the same ratio or some multiple of it.

✔️✔️For example:-

⭕️Sulphur and Carbon both form compounds with hydrogen.

⭕️But in methane 12 g of carbon react with 4 g of hydrogen.

⭕️In hydrogen sulphide, 32 g of sulphur react with 2 g of hydrogen.

⭕️Sulphur and carbon form a compound in which the C: S ratio is 12:64 (i.e. CS2).

Answer 2

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


$\huge\textbf{Law of Reciprocal}$

$\huge\textbf{Proportion :}$


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;

$C$ = 12 gm

$O_{2}$ = 32 gm

→ Ratio of $2H_{2}\::O_{2}$

= 4 : 32

= 1 : 8

2) $C\:+\:O_{2}$ ----> $CO_{2}$

* $2H_{2}\:+\:O_{2}$ ----> $2H_{2}O$

→ Ratio of $C\::H$

= 12 : 4

= 3 : 1
