Question

copper gives two oxides .on heating 1gram of each in hydrogen,we get 0.888gram and0.798gram of the metal respectively .show that these results are in agreement with the law of multiple proportion ​

Answer 1

Answer:

Let the two oxides by cu be A and B

Oxide A:-

Mass of Cu in 1g=0.888g

Mass of O in 1g=1−0.888=0.112g

Oxide B:-

Mass of Cu in 1g=0.799g

Mass of O in 1g=1−0.799=0.201g

In oxide A:- 0.112×

0.888

1

=0.126g

In oxide B:- 0.201×

0.799

1

=0.252g

So, 0.126 and 0.252 are the figure of Cu combined with oxygen in both the oxides.

∴ Ratio=0.126:0.252

or 1:2

∴ This is a simple whole ratio that shows that argument with the law of multiple properties.

Answer 2

Answer:

0.888gramssssssssssssss
