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)
