Which answer can be used to illustrate the law of multiple proportions?
naf, nabr
hci, ci2
so, so2
co2, h2co3
ch4, co2

SO and SO2

Explanation:

Law of multiple proportion states that when two elements combine with each other to form a compound, the mass of one element that combines with a fixed mass of the other element are always in ratio of whole numbers.

Here the elements that combine are sulfur and oxygen. Oxygen combines with a fixed mass of sulfur,i.e. 32 g( molar mass of sulfur is 32 g / mole).the mass of oxygen that combines with 32 g of sulfur in SO and SO2 is 16 g and 32 g(molar mass of oxygen is 16 g).

The ratio of  mass of oxygen  in SO and SO2 is

16:32

= 1:2.

This is accordance with law of multiple proportion.

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.
