Document Summary
January 1999: consider the following redox reaction: The reducing agent is: h2o, clo3, mno2, mno4, consider the following reaction that occurs in a breathalyzer: 2- (aq) + 16h+ (aq) + 3c2h5oh(g) 4cr3+ (aq) + 11h2o(l) + 3ch3cooh(aq) The reduction half-reaction that occurs is: clo2, clo2, clo2, clo2. + 2h2o + 4e- cl- + 4oh- + 2h2o cl- + 4oh- + 4e- + h2o + 2e: vanadium metal, v, reacts spontaneously with cd2+ , but not with ti2+ . Based on these results, the order of oxidizing agents, from strongest to weakest, is: cd2+, v2+, ti2, v2+, ti2+ , cd2, ti2+, cd2+, v2, ti2+, v2+, cd2, consider the following electrochemical cell: April 1999: which of the following represents the formation of a stronger acid as a result of oxidation, h2so3 h2s, hclo4 hcl, h2so3 h2so4. H2co3: hco3, chlorine has an oxidation number of +5 in, naclo, naclo2, naclo3, naclo4, consider the following:
