Natural sample of cupric carbonate contains 51.35% of copper, 9.74% of oxygen and 38.91% of carbon. Synthetic sample of the compound will contain:
Natural sample of cupric carbonate contains 51.35% of copper, 9.74% of oxygen and 38.91% of carbon. Synthetic sample of the compound will contain:
The correct option is A
51.35% of Copper, 9.74% of oxygen and 38.91% of carbon
Explanation for correct option.
1. According to the law of definite proportions every chemical compound contains fixed and constant proportions (by mass) of its constituent elements.
2. Therefore, a compound will contain the same mass of elements irrespective of the origin of the compound.
3. Hence in the given illustration, both natural and synthetic samples contain same amount of copper.
Explanation for incorrect option.
From the law of definite proportions it is clear that a given compound always contains exactly the same proportion of elements by weight irrespective of its source, therefore their must be same composition and in all options expect (A) composition is different, therefore these options are incorrect.
Conclusive statment- option (A) is correct.
