Law of reciprocal proportion

Vedclass · Answer

(C) The Law of Reciprocal Proportion states that when two different elements combine separately with a fixed mass of a third element,the ratio of the masses in which they do so is either the same or a simple multiple of the ratio in which they combine with each other.Given:$1 	ext{ part of } A$ combines with $2 	ext{ parts of } B$.$6 	ext{ parts of } C$ combine with $4 	ext{ parts of } B$.To compare $A$ and $C$ with a fixed mass of $B$ (let's fix $B$ at $4 	ext{ parts}$):$A$ combines with $B$ in ratio $1:2$,so $2 	ext{ parts of } A$ combine with $4 	ext{ parts of } B$.$C$ combines with $B$ in ratio $6:4$,so $6 	ext{ parts of } C$ combine with $4 	ext{ parts of } B$.The ratio of masses of $A$ and $C$ that combine with a fixed mass of $B$ is $2:6$ or $1:3$.Since the ratio of weights of $A$ and $C$ is governed by their reaction with a third element $B$,this follows the Law of Reciprocal Proportion.

One part of an element $A$ combines with two parts of another element $B$. Six parts of the element $C$ combine with four parts of the element $B$. If $A$ and $C$ combine together,the ratio of their weights will be governed by
