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

Answer»

Carbon
Oxygen
Both carbon and oxygen
Neither carbon nor oxygen

Solution :REACTION 1:`C+O_2to 2CO`
`2xx12` G carbon COMBINE with 32G of oxygen.
Hence, EQUIVALENT mass of carbon `=(2xx12)/(32)xx2=6`
Reaction 2: `C + O_2 to CO_2`
12 g carbon combine with 32 g of oxygen.
Hence, Equivalent mass of carbon `=(12)/(32)xx8=3`
