14g of element X combine wilh 16 g of oxygen. On the basis of this information, which of the followings is a correct statement?

The element X could have an atomic weight of 7 and its oxide is XO

The element X could have an atomic weight of 14 and its oxide formula is `X_2O`

The element X could have an atomic weight of 7 and its oxide is `X_2O`

The element X could have an atomic weight of 14 and its oxide is `X_2O`

Fructose is laevorotatory

`alpha`-glucose and `beta-`glucose differ in configuration at anomeric carbon

The linkage connecting `alpha`-glucose and `beta-`fructose in sucrose is known as glycosidic linkage

Fructose is dextro rotatory

CO and `H_2` are fractionally separated using differences in their densities

CO is removed by absorption in aqueous `Cu_2Cl_2` is solution

`H_2` is removed through occlusion with Pd

CO is oxidised to `CO_2` with steam in the presence of a catalyst followed by absorption of `CO_2` in alkali
