MCQ
$1.0\, g$ of an oxide of $A$ contained $0.5\, g$ of $A$. $4.0\,g$ of another oxide of $A$ contained $1.6 \,g$ of $ A$. The data indicate the law of
  • A
    Reciprocal proportions
  • B
    Constant proportions
  • C
    Conservation of energy
  • Multiple proportions

Answer

Correct option: D.
Multiple proportions
d
According to the law of multiple proportion, when two elements combine with each other to form more than one compound, the weights of one element that combines with fixed weight of the other are in the ratio of small whole numbers.
