If 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 (a) Is this statement true? (b) If yes, according to which law? (c) Give one example related to this law.

Question

Philoid · Accepted Answer

(a) Yes, the statement is true.

(b) This statement is the definition of the law of multiple proportions.

(c) An example of an application of this law is the reaction of hydrogen and oxygen to form water H₂O as well as hydrogen peroxide H₂O₂.

H₂ + 1/2O₂→ H₂O

2g 16g 18g

H₂ + O₂→ H₂O₂

2g 32g 34g

Experimentally, the masses of the reactants and products are given. The ratio of masses of oxygen with the fixed mass of hydrogen is 16:32 or 1:2 which is a simple whole-number ratio.
