Question

Carbon and hydrogen forms three different compounds A, B and C in which the percentage of carbon are 75%, 85.7% and 92.3% respectively. Which law of chemical composition can be illustrated with these data?

Answer 1

Law of multiple proportions

Step-by-step explanation:

The law which is illustrated with the data suggests the law of multiple proportion.

The combining elements are carbon and hydrogen;

Law of multiple proportions states that "if two element combine together to form tow or more different compounds, the masses of one of the elements which separately combine with a fixed mass of the other element are in a simple ratio".

Let us prove the law of multiple proportion:

In A;

C = 75% H = 25% = 3:1

B;

C = 85.7 H =14.3 = 6:1

C;

C = 92.3 H = 7.7 = 12:1

We see that both carbon and hydrogen have a fixed ratio.
