Question

-----Which of the following answers best describes the Law of Multiple Proportions as it related to the bonding types in carbon as described above.

Answer 1

Answer:

Law of Multiple proportion states that when two elements combine to form more than one compound, the mass of one element, which combines with a fixed mass of the other element, will always be ratios of whole numbers.

For example, let us assume 2 molecules CO (carbon monoxide) and CO2

​  

(carbon dioxide).

CO= 12gm of carbon + 16 grams of Oxygen.

CO  2

​  

= 12gm carbon+ 32 grams of Oxygen.

The ratio of the mass of oxygen in the given two compounds is 16:32=1:2.

Thus law of multiple proportions is proved.

Answer 2

When two elements mix to make more than one compound, the mass of one element, which combines with a fixed mass of the other element, will always be ratios of whole numbers, according to the Law of Multiple Proportion.

Assume two molecules of $CO$  (carbon monoxide) and $CO_{2}$ (carbon dioxide).

($CO_{2}$) (carbon dioxide)

$CO_{2}$ is made up of 12 grammes of carbon and 16 grammes of oxygen.

$CO_{2}$ is made up of 12 grammes of carbon and 32 grammes of oxygen.

The mass of oxygen in the aforementioned two compounds has a ratio of 16:32=1:2.

The law of multiple proportions is therefore established.
