Answer 1

bottom layer is bromoform.

Bromoform is n-e-Ber and its density Ben is 2.88 g lam3 or 2.88 g 1 me Water has a dersity of 0.997 g/cm3 It is a general property that if two substances are added and leave for sometime then the substance with less. density will automatically come uplupper layer) and the substance with more density will go down (bottom layer). So, Water has low density. Hence will form upper layer and bromoform which has high density will form bottom layer. I Rottom layer Bottom layer - or Bromoform water 1 Upper layer
