1)
The greater the surface area of the packing of the fractionating column,
The lower its efficiency
The faster the distillation will proceed
Efficiency doesn't depends on the surface area of the column
The greater its efficiency
2)
When the vapour pressure of a liquid equals atm pressure, the temperature of the liquid equals:
The normal boiling point
The boiling point
100°C
The Vapourisation point
3)
The separation technique shown in the diagram is
Chromatography
Filtration
Crystallization
Fractional distillation
4)
Two completely miscible liquids can be separated by
Fractional distillation
Separating funnel
Sublimation
Steam distillation
5)
In distillation of a mixture of two components, the first compound to condense into the receiving flask will be:
The one with the lower boiling point
The one with the higher boiling point
The one with the higher melting point
The one with the lower melting point
