  13. Monday, February 18 Objective: Students will be able to predict products of chemical reactions and predict if products are soluble. Bell Ringer: Predict the products of the following chemical reactions: a) C2H6+O2 b) CuCl2+ Li2S  c) F2 + Li2O  CO2 + H2O CuS + LiCl O2 + LiF

  14. Predicting Products of Chemical Reactions 1. Single Replacement K+1 Cl-1 + F2 = KCl + F2 2. Double Replacement K+1 SO4-2 + Cu+2 NO3-1 = K2SO4 + Cu(NO3)2 CO2 + H2O 3. Combustion 4. Synthesis Li+1 Cl-1 = LiCl Ba + O2 5. Decomposition

  28. Precipitates in Double Replacement Reactions • Many DR reactions occur in water- that is, in aqueous solution • When dissolved in water, many ionic compounds “dissociate”, or separate, into cations and anions • If the rearrangement of the ions forms a solid it iscalled a precipitate. • A precipitate is a solid produced during a chemical reaction in a solution.

  29. Cornell Notes (continued) What type of chemical reaction? Double Replacement Switch Cations Find Charges Flip & Drop  for Precipitate? Na3PO4+ BaCl2 Ba+2PO4-3+ Na+1 Cl-1 Barium phosphate is not soluble so a precipitate forms Ba3(PO4)2 (s) + NaCl(aq)

  30. Example AgNO3 + NaCl AgCl + NaNO3 1. First, we separate the compounds into ions: Ag1+ + NO31- + Na1+ + Cl1- 2. Next we “switch” the cations 3. Last we determine if a precipitate will form using the solubility chart AgCl + Na1+ + NO31- Note that the AgCl did not ionize, because it is a “precipitate”
