Question

which one of then following pairs of compounds illustrates the law of multiple proportions?

a]H2O,Na2O b]MgO,Na2O

c]Na2O,BaO c]SnCl2,SnCl4

e]H2O,H2S

Answer 1

OPTION C ....SAME ELEMENTS IN TWO DIFFERENT COMPOUNDS

Answer 2

Answer: The correct answer is Option c.

Explanation:

Law of multiple proportions states that when two elements combine to form two or more compounds in more than one proportion, the mass of one element that combine with a given mass of the other element are present in the ratios of smallest whole number.

For Example: $CuO\text{ and }Cu_2O$ follow law of multiple proportions.

For the given options:

Option 3 compound are $SnCl_2\text{ and }SnCl_4$ which follow law of multiple proportion because here, chlorine atom is present in 1 : 2 ratio.

Thus, the correct answer is Option c.
