Quiz 7Name: ____________________________________Chemistry 102, Lec 401 – Fall 2013DS Section: (1 point) _________________________1.Complete the table for the combination.4 pointsSilver nitrate and lead (in water)Oxidation half‐reactionPb(s)→Pb2+(aq) + 2e−Reduction half‐reactionAg+(aq) + e→Ag(s)Net ionic equation2Ag+(aq) + Pb(s)→2Ag(s) + Pb2+(aq)Oxidizing agent:AgNO3(aq)Reducing agent:Pb(s)2.What is the oxidation state of chlorine in each of the substances?2 pointsNaClO3+5Cl203.A student assigns the oxidation number of hydrogen in water to be +2. What is wrongwith this?1 pointBecause we assign oxidation numbers assuming 100% ionic character, we are implyinghydrogen has a +2 ionic charge. This would mean hydrogen has lost 2 electrons, but ithas only 1.4.Using a 0.125 M Fe(NO3)3(molar mass = 241.88 g∙mol−1), complete the table.
