Question

law of reciprocal proportion
​

Answer 1

Answer:

law of reciprocal proportion

Answer 2

Answer:

Law of reciprocal proportion states that the ratio of the masses in which two different elements combine independently with a fixed mass of a third element is either the same as or a simple multiple of the ratio of the masses in which they combine with each other.

Explanation:

According to the law of reciprocal proportion, the ratio of the masses in which two different elements combine independently with a fixed mass of a third element is either the same as or a simple multiple of the ratio of the masses in which they combine with each other.

Example

3 g Carbon + 1 g Hydrogen → methane

8 g oxygen + 1 g hydrogen → water

Then the mass ratio of carbon and oxygen is 3:8.

12 g carbon + 32 oxygen → carbon dioxide

Mass ration of carbon and oxygen = 12:32 = 3:8

⇒ When C and O join with one other, their mass ratio is the same as when they combine individually with a fixed quantity of H.
