Mention the method of separation which you will use to separate the components from the following mixtures? a) different coloured pigment from the petals of flowers b) sodium chloride from its solution in water c) small pieces of metals from teh engine oil d) acetone from water

A) Use paper chromatography to separate pigments

B) Use distillation (a condenser by boiling off the water and getting the NaCl)

C) Use filtration by using filter paper

D) Use fractional distillaton with fractionating beads to boil both liquids with an electric heater and thermometer to control the boiling points of both liquids

the catch is that the top numbers are atomic masses the bottom numbers are the numbers of protons and electrons in an uncharged atom. they are the number of that atoms as you would find them on the periodic table. further, the numbers on the left are used to determine the missing numbers on the right

so here we go

atomic mass

239 + 1 = y + 134 + 3 combine like terms

240 = y + 137             subtract 137 from both terms

240 - 137 = y

103 = y

atomic number

94 = z +54 + 0

94 = z + 54               subtract 54 from both sides.

40 = z
