The temperature-time graph above represents the distillation of a mixture of unknown alcohols and water. Explain how you can use a temperature-time graph of a distillation to determine what compounds are present in an unknown mixture.  (3 marks)

Consider the following pairs of reactants which will be mixed in solution: a)  K2S(aq)  +  CaBr2(aq)  –> b)  KOH(aq)  +  BaCl2(aq)  –> c)  Na3PO4(aq)  +  AgNO3(aq)  –> If the products include a precipitate, write the balanced chemical equation for the reaction (including all subscripts). If no precipitate will form write “no precipitate” after the reaction arrow.      (8 marks)
