  1. Review of Ch 9 & 11 Writing and Balancing Equations

  2. Writing Formulas • Magnesium sulfide • Sodium phosphate • Barium hydroxide • Copper (II) nitrite • Trihydrogen bromide • Calcium carbonate • Hexafluoride pentanitride • Iron (III) sulfate MgS Na3PO4 Ba(OH)2 Cu(NO2)2 H3Br CaCO3 F6N5 Fe2(SO4)3

  3. Naming • NaClO3 • Hg2Br2 • K2CrO4 • HClO4 • SnO2 • Fe(C2H3O2)3 • Ca(OH)2 Sodium chlorite Mercury (I) bromide Potassium chromate Hydrogen chlorate Tin (IV) oxide Iron (III) acetate Calcium hydroxide

  4. Balance • PbO2 PbO + O2 • Fe(OH)3 Fe2O3 + H2O • (NH4)2CO3 NH3 + H2O + CO2 • NaCl + H2SO4  Na2SO4 + HCl 2PbO22PbO + O2 2Fe(OH)3 Fe2O3 + 3H2O (NH4)2CO3 2NH3 + H2O + CO2 2NaCl + H2SO4  Na2SO4 + 2HCl

  5. Type? • Hf + N2 Hf3N4 • Mg + H2SO4 MgSO4 + H2 • C2H6 + O2  CO2 + H2O • Pb(NO3)2 + NaI  PbI2 + NaNO3 • Fe + O2  Fe3O4

  6. Write a Complete Chemical Equation 1. Bubbling chlorine gas through a solution of potassium iodide give elemental iodine and a solution of potassium chloride. 2. Solid tetraphosphorus decoxide reacts with water to produce phosphoric acid.

  7. Predict the Products • C3H8 reacts with oxygen 2. Copper reacts with aqueous silver nitrate 3. Aluminum reacts with bromine 4. Lead (II) nitrate reacts with potassium iodide

  8. Predict the Products • C3H8 reacts with oxygen 2. Copper (II) reacts with aqueous silver nitrate 3. Aluminum reacts with bromine 4. Lead (II) nitrate reacts with potassium iodide C3H8 + 5O2 3CO2 + 4H2O Cu + 2AgNO3 Cu(NO3)2 + 2Ag 2Al + 3Br2 2AlBr3 Pb(NO3)2 + KI  KNO3 + PbI2
