Question

State the law of chemical combination illustrated by the pair of compounds CO

and CO2?​

Answer 1

Answer:

its law of multiple proportion.

Explanation:

Law of multiple proportions, statement that when two elements combine with each other to form more than one compound, the weights of one element that combine with a fixed weight of the other are in a ratio of small whole numbers.

Answer 2

The law of chemical combination illustrated by the pair of compounds CO and CO₂ is 'The Law of Multiple Proportions'.

• The Law of Multiple Proportions states that if two elements form more than one compound, then the ratios of the masses of the second element which combine with a fixed mass of the first element will always be ratios of small whole numbers.

• In the given pair, the elements C and O form two compounds. In CO and CO₂, the number of atoms of the first element (C) remains constant, whereas the second element (O) combines with C in ratios of small whole numbers (1:2).

• The Law of Multiple Proportions thus holds true and is illustrated by the pair CO and CO₂.
