Which of the following law does this data illustrate: 12  g carbon combines with 64   g sulphur to form C S 2 . 12   g carbon also combines with 32 g oxygen to form C O 2 . 10   g sulphur combines with 10 g oxygen to form S O 2 .

Options

  1. ALaw of multiple proportions
  2. BLaw of definite proportions
  3. CLaw of reciprocal proportions
  4. DLaw of gaseous volumes.

Correct answer

C. Law of reciprocal proportions

Step-by-step solution

Ratio of the weights of S and O combining with fixed weight of C is 64 : 32 = 2 : 1 . Ratio of the weights of S and O c o m b i n i n g d i r e c t l y = 10 : 10 = 1 : 1 . The two ratios are simple multiple of each other. This proves law of reciprocal proportions.
