Question

Explain law of resiprocal proportion. with one explained example .​

Answer 1

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". ... The mass ratio of C:O=3:8 .

Answer 2

Answer: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."

eg: Consider 3 grams of C reacting with 1 g of H to form methane.

Also, 8 g of O reacting with 1 g of H to form water.

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

Similarly, 12 g of C reacts with 32 g of O to form CO2.

The mass ratio of carbon and oxygen is 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.
