Question

Copper gives two oxides. On heating 1.0gm of each
in hydrogen gas, 0.888gm and 0.799gm of the metals are produced.show that the results agree with the law of multiple proportion.​

Answer 1

Answer:

Sorry I don't now the answer

Explanation:

Answer 2

In the compound that yields 0.888 g of Cu, the remainder of the 1 g must by O, so that would be 0.112 g O. The parts of Cu that combine with 1 part of O =0.888/0.112 = 7.93

In the compound that yields 0.799 g of Cu, the remainder of the 1 g must be O, so that would be 0.201 g. The parts of Cu that combine with 1 part of O = 0.799/0.201 = 3.98.

The ratio of Cu that combines with a fixed mass of O is 7.93:3.98 or 2:1.
