MCQ
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. The data illustrates
  • A
    Law of reciprocal proportions
  • B
    Law of constant proportions
  • ✓
    Law of multiple proportions
  • D
    Law of equivalent proportions
✓

Answer

Correct option: C.
Law of multiple proportions
c
The data shows that the weights of lead combining with fixed weight of oxygen are in the ratio $1 / 2: 1$ or $1: 2$ which is in accordance with law of multiple proportions.
