Question

If two elements can combine toform more than one compound, the masses of one element that
combine with a fixed mass of the other element, are in whole number ratio.
(a) Is this statement true?
(b) If yes, according to which law?
(c) Give one example related to this law​

Answer 1

Explanation:

When two elements can combine to form more than one compound, the masses of one element that combine with a fixed mass of the other element, are in whole number ratio. This is the law of multiple proportions.

Consider two elements C and O. They combine to form CO and CO

2

.

The masses of oxygen that combine with 12 g of carbon to form CO and CO

2

are 16 g and 32 g respectively. They are in whole number ratio 1:2.

Answer 2

Answer:

(a) Yes

(b) According to the law of multiple proportion.

(c) hydrogen and oxygen react to produce two compound, Water & Hydrogen peroxide. Masses of oxygen which combine with fixed mass of hydrogen are in simple ratio.

H2 +O2 - H2O
