- BFalse

5Oxygen and nitrogen gas are produced by [blank_start]fractional[blank_end] distillation of air:
-[blank_start]dust[blank_end], water [blank_start]vapour[blank_end] and carbon dioxide are removed from the air
-air is cooled to -[blank_start]200[blank_end]c and all gases become liquids
-the temperature is gradually allowed to rise, and at about -[blank_start]196[blank_end]c [blank_start]nitrogen[blank_end] vaporises and is collected as a gas
-the remaining liquid is mostly [blank_start]oxygen[blank_end]- Afractional
- Bdust
- Cvapour
- D200
- E196
- Fnitrogen
- Goxygen
6[blank_start]Chromatography[blank_end] can be used to separate and i[blank_start]dentify[blank_end] components in substances such as colours in foods.
Different colours move different [blank_start]distances[blank_end] up the paper. A developed [blank_start]chromatogram[blank_end] shows a spot for each substance in a mixture.
The distance travelled by a component is described using Rf values; Rf values = distance travelled by [blank_start]component[blank_end] / distance travelled by [blank_start]solvent[blank_end]- AChromatography
- Bdentify
- Cdistances
- Dchromatogram
- Ecomponent
- Fsolvent
