Question 1 Report
2.85g of an oxide of copper gave 2.52g of copper on reduction and 1.90g of another oxide gave 1.52g of copper on reduction. The data above illustrates the law of?
Answer Details
The data given in the question illustrates the law of multiple proportions. This law states that when two elements combine to form two or more compounds, the mass of one element that combines with a fixed mass of the other element are in a ratio of small whole numbers. In the given question, we have two different oxides of copper, and the mass of copper produced on the reduction of these oxides shows a ratio of small whole numbers. Specifically, the ratio of the masses of copper produced is 1.66:1, which can be simplified to 5:3. This indicates that the two oxides have a different ratio of copper to oxygen, as predicted by the law of multiple proportions.
