From the given information, select the suitable law of chemical combination: Cupric Carbonate % of Cu % of C % of O Natural Sample 51.35 9.74 38.91 Synthetic Sample 51.35 9.74 38.91

Options

  1. ALaw of Multiple Proportions
  2. BGay Lussac's Law of Gaseous Volumes
  3. CLaw of Definite Proportions
  4. DLaw of Conservation of Mass

Correct answer

C. Law of Definite Proportions

Step-by-step solution

The given data shows that the percentage composition of elements (Cu, C, and O) in cupric carbonate is identical for both the natural and synthetic samples. This indicates that a pure chemical compound always contains the same elements combined together in the same definite proportion by mass, irrespective of its source or method of preparation. This observation is in accordance with the Law of Definite Proportions. Answer: Law of Definite Proportions
