Question

The law of multiple proportions is illustrated by the compounds _______.
(A) carbon monoxide and carbon dioxide
(B) potassium bromide and potassium chloride
(C) ordinary water and heavy water (D₂O)
(D) calcium hydroxide and barium hydroxide

Answer 1

Option A as law of multiple proportions talk about the ratios of two compounds consisting of the same elements in integral values.

Answer 2

Hey dear,

● Answer - (A) carbon monoxide and carbon dioxide
Law of multiple proportions is illustrated by the compounds *carbon monoxide and carbon dioxide*.

● Law of multiple proportions -
- It states that when two elements combine with each other to form more than one compound, the weights of one element that combine with a fixed weight of the other are in a ratio of small whole numbers.

In CO 16 g of O combines with 12 g C & in CO2 32 g of O combines with 12 g C. Ratio of O combining with fix weight of C is 1:2. This proves law of multiple proportions.


Hope this is helpful. Thanks dear..
