Question

carbon forms two oxides namely carbon monoxide and carbon dioxide. the equivalent mass of which element remains constant

Answer 1

Answer ⇒ Option (b). Oxygen.

Explanation ⇒

When two elements combines to forms more than one compound, then the ratio of the masses of the elements which combines with the fixed mass of the other elements is the simple whole number ratio.

In the above question, Mass of the oxygen in both the compound is constant. This means that the different masses of the carbon will combines with the fixed mass of the Oxygen to form Carbon monoxide and carbon dioxide.

Hence, the ratio of the masses of the Carbon will be simple whole number ratio and the mass of the Oxygen will be constant.

Hence, Option (b). Oxygen is correct.

Hope it helps.

Answer 2

Answer:

The equivalent mass of oxygen remains constant. .....

Explanation:

★ C + O2 -----------> CO2

12g 32g

★ 2C + O2 ----------> 2CO

24g 32g

THUS 32g OF OXYGEN REMAINS CONSTANT ....
