Answer 1

Answer:

Option (d) According to Law of Multiple Proportions,  when two elements combine to form more than one compound, the mass of one element, which combines with a fixed mass of the other element, will always be in simple ratio. for example, if C and O combine two form CO and CO₂, here in CO , 12g of C ⇔16 g of O

or, 1g of C ⇔ 1.33g of O in CO₂,

12g of C ⇔ 32g of O

or, 1g of C ⇔ 2.66 of O

It is clear that 1.33 : 2.66 = 1 : 2 is in simple ratio so, CO and CO₂ follows law of multiple proportions.

From the  above explanation, all the first three options follow the law but last option , (d) Na₂S , NaF doesn't follow because here three elements are given Na₂S and F .But law of multiple proportions is valid for two elements.
