Carbon forms two oxides, namely carbon monoxide and carbon dioxide. The equivalent mass of which element remains constant ?

A

Carbon

B

oxygen

C

both carbon and oxygen

D

neither carbon nor oxygen

Text Solution

Verified by Experts

The correct Answer is:
B
React 1 : `2C+O_2 to 2CO`
`2xx12g` carbon combines with 32 g of oxygen
`therefore` Equivalent mass of carbon `=(2xx12)/(32)xx8=6`
React 2 : `C+O_2 to CO_2`
12g carbon combines with 32g of oxygen
`therefore` Equivalent mass of carbon `(12)/(32)xx8=3`.
