Which of the following is an acid base reaction? C(s) + O2(g) rightarrow CO2(g) Fe(s) + 2 AgNO3(aq) rightarrow 2 Ag(s) + Fe(NO3)2(aq) 2 HClO4(aq) + Ca(OH)2(aq) rightarrow 2 H2O(l) + Ca(ClO4)2(aq) MgSO4(aq) + Ba(NO3)2(aq) rightarrow Mg(NO3)2(aq) + BaSO4(s) None of the above are acid base reactions. Identify the spectator ions in the following molecular equal KBr(aq) + AgNO3(aq) rightarrow AgBr(s) + KNO3(aq) Ag+ and NO3- K+ and K+ and Br- Ag+ and Br- There are no spectator ions in this reaction Which of the following is a precipitation reaction? HCl(aq) + KOH(aq) rightarrow KCl(aq) + H2O(l) NaCl(aq) + Lil(aq) rightarrow Nal(aq) + LiCl(aq) 2 Lil(aq) + Hg2(NO3)2(aq) rightarrow Hg2l2(s) + 2 LiNO3(aq) Zn(s) + 2 AgNO3(aq) rightarrow 2 Ag(s) + Zn(NO3)2(aq) None of the above are precipitation reactions. Give the net ionic equation for the reaction (if any) that occurs when aqueous solutions of H2SO4 and KOH are mixed. H+(aq) + OH-(aq) rightarrow H2O(l) H+(aq) + OH-(aq) + 2K+(aq) + -(aq) rightarrow H2O(l) + K2SO4(s) (aq) + OH-(aq) rightarrow H2(OH)2(l) 2K+(aq) + -(aq).rightarrow K2SO4(s) No reaction occurs. Give the net ionic equation for the reaction (if any) that occurs when aqueous solutions of K2S and Fe(NO3)2 are mixed. Fe2+(aq) + S2- (aq) + 2 K+(aq) + 2 (aq) rightarrow FeS(s) + 2 K+(aq) + 2 -(aq) Fe2+(aq) + S2-(aq) + 2 K+(aq) + 2 -(aq) rightarrow Fe2+(aq) + S2-(aq) + 2 KNO3(s) Fe2+(aq) + S2(aq) rightarrow FeS(s) K+(aq) + -(aq) rightarrow KNO3(s) No reaction occurs. Choose the statement below that is TRUE. The term "weak electrolyte" means that the substance is inert. A strong acid solution consists of only partially ionized acid molecules. A molecular compound that does not ionize in solution is considered a strong electrolyte. A weak acid solution consists of mostly nonionized acid molecules. The term "strong electrolyte" means that the substance is extremely reactive. Show transcribed image text
