Which one of the following pairs of substances illustrate the law of multiple proportions? o a. 03, o2 ob. d20, h20 (d = deuterium) o c. sio2, sb203 od. kci, mgcl2 o e. pc13, pci

The correct answer is: PCl₃ and PCl₅

Explanation:

Law of multiple proportions, also known as the Dalton's Law, states that the when the two different chemical elements combine in order to form two or more than two chemical compounds, then the ratio of mass of the chemical element that combines with the fixed mass of other chemical element is the ratio of small whole numbers.

Example: PCl₃ and PCl₅

explanation:

venn diagram is pictorial representation with of circles showing the relation between two finite sets or things. the intersection part of two circles conveys the relation present in between those sets or things.

here in the venn diagram of sand and salt two circles represent sand and salt. but the area falling under the intersection of these circle represents the mixture of sand and salt.

so, in a venn diagram the mixture will be placed in a middle that is in between the intersection of two circles.
