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 |
- A Law of Multiple Proportions
- B Gay Lussac's Law of Gaseous Volumes
- C Law of Definite Proportions
- D Law of Conservation of Mass
Answer & Solution
Correct Answer
(C) Law of Definite Proportions
Step-by-step Solution
Detailed explanation
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.
