Acc Chemistry Chapter 8 Worksheet #2 Name KEY!!! #2 Your instructor used the following symbols for phases on this sheet: (s) (l) (g) (ppt) (aq) Anywhere where you don’t see phases, your instructor determined that phases in that equation would be difficult for students to do, so he didn’t list them for that example. Please note that your instructor replaced the balancing numbers with types of reaction; see key #1 for those numbers. Please note that your instructor named all the chemicals that it would be appropriate for you to know how to name. Acids (chemicals that start with the letter “H” in the formula), get named just like ionic compounds at this point of the course – name the front, then name the back. Fe(s) + O2(g) Iron oxygen Mg(s) + H3PO4(aq) Magnesium hydrogen phosphate Strontium nitrate hydrogen sulfate O2(g) Sulfur dioxide oxygen Al(OH)3 + H2SO4(aq) +NaCl(aq) Cl2(g) Aluminum chlorine HNO3(aq) + + synthesis Al2(CO3)3 + aluminum carbonate HCl(aq) + NaOH H2CO3(aq) Na2CrO4 Na2SO4(aq) synthesis Pbl2(ppt) + KNO3(aq) lead (II) iodide potassium nitrate + BaCO3(ppt) barium carbonate NaOH + + BaCrO4 H2S double replacement MgO + MgCrO4 potassium bromide + + HCl CO2(g) Oxygen carbon dioxide water HCl + Calcium carbonate hydrogen chloride BF3 + H2O Water magnesium bromide O2(g) Magnesium chromate hydrogen chloride CaCO3 + MgBr2 + MgCl2 + calcium chloride B2O3 K2O CO2 combustion H2CrO4 double replacement hydrogen chromate + carbon dioxide + double replacement potassium oxide H2O(g) magnesium chloride CaCl2 double replacement barium chromate hydrogen sulfide KBr double replacement hydrogen chloride sodium hydroxide FeCl3 double replacement HCl(aq) iron (III) chloride C2H4(g) double replacement sodium sulfate AlCl3(s) sodium chromate HCl + double replacement sodium hydroxide Iron (III) sulfide hydrogen chloride Magnesium oxide double replacement hydrogen nitrate SO3(g) hydrogen carbonate Barium hydroxide + single replacement aluminum chloride potassium iodide Barium chloride Fe2S3 + SrSO4(ppt) hydrogen chloride Pb(NO3)2(aq) + Kl(aq) Ba(OH)2 hydrogen sodium carbonate Al(s) + BaCl2(aq) H2(g) magnesium phosphate sulfur trioxide Hydrogen sulfate sodium chloride Lead (II) nitrate Mg3(PO4)2(ppt) + strontium sulfate Na2CO3 Aluminum hydroxide synthesis iron (III) oxide Sr(NO3)2(aq) + H2SO4(aq) SO2(g) + Fe2O3(s) HF hydrogen fluoride H2O double replacement water double replacement Cu(NO3)2 (s) Copper (II) nitrate Ammonium dichromate NH3 N2(g) + H2O water HSbCl4 H2S NO2 + O2 decomposition nitrogen dioxide oxygen + nitrogen Iron (III) chloride ammonia + + copper (II) oxide (NH4)2Cr2O7(s) FeCl3 + CuO Cr2O3(s) + H2O(g) decomposition chromium (II) oxide water Fe(OH)3 + iron (III) hydroxide Sb2S3 + ask if you’re curious NH4Cl ammonium chloride HCl double replacement That’s enough naming for now. Why not go to a worksheet and work on writing formulas….. Calcium + Water Ca + 2 H2O yields Ca(OH)2 Calcium hydroxide Sodium carbonate + Hydrogen chloride Na2CO3 + 2HCl yields H2CO3 Calcium nitrate + Aluminum phosphate 3 Ca(NO3)2 + 2 AlPO4 Barium hydroxide + Ba(OH)2 + hydrogen + H2 Hydrogen carbonate + Sodium chloride + 2 NaCl + Aluminum nitrate yields Ca3(PO4)2 + 2 Al(NO3)3 Sodium + Barium + 2Na yields 2 NaOH + Ba Magnesium sulfide + Hydrogen fluoride MgS + 2 HF yields MgF2 Calcium phosphate Sodium hydroxide Magnesium fluoride + + Hydrogen sulfide H2S Here are three things that you can do to do better on your chapter 8 test. 1. On the front of this page, write names underneath the chemicals. 2. On the front of this page, write phases behind each chemical. 3. On the front of this page, identify the types of reactions.
