hi ill give you a mark scheme answer:
1)turn on h20 , fill condenser
2)heat flask and bunsen burner
3)h20 and ethanol turn to vapour
4)fractionating column has a temp gradient, ethanol and water seperate due to different boiling points
5)only ethanol goes into condenser
6)condenser used to cool vapour and condense ethanol into liquid
