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

Options

A. Carbon
B. Oxygen
C. Both carbon and oxygen
D. Neither carbon nor oxygen

Answer

B

Explanation

Reaction 1: `2CO + O_(2) to 2CO`
`2xx12` g of carbon combines with 32 g of oxygen
Hence, Equivalent mass of carbon = `(2xx12)/32xx8=6`
Reaction 2 :`C + O_(2) to CO_(2)`
12 g carbon combines with 32 g of oxygen.
Hence, Equivalent mass of carbon =`12/32xx8=3`
