Question
Two samples of lead oxide were separately reduced to metallic lead by heating in a current of hydrogen. The weight of lead from one oxide was half the weight of lead obtained from the other oxide for a gram of oxygen removed. The data illustrates:

Solution
The correct option is C Law of multiple proportions
Law of multiple proportions states that if two elements form more than one compound between them, then the ratios of the masses of the second element which combines with the fixed mass of first element will always be ratio of small whole numbers.
According to the data, weight of lead that combines with a fixed mass of oxygen is in the ratio of 1 : 2 thus illustrating the law of multiple proportions.
