From the Standard Potential Table in your general chemistry textbook:

Half-reactions are written as _________ reactions with charge and mass balanced.

Among the ions, Cd2+Pb2+ & Ca2+ ,__________ has the greatest ability to reduce to its neutral metal.
(Use ^ for superscripting)

Among the neutral metals; Pb, Ca & Cd, ____________ has the least ability to oxidize to the +2 ion.
(No special characters are need for subscripting)

  • Chemistry - ,

    The reactions are written as reductions reactions.
    For questions 2 and 3, look up the reductin potentials in your text. The ions with the largest negative potential are the hardest to reduce.

  • Chemistry - ,

    I think half reactions are redox
    and Pb has the greatest ability to reduce its neutral metal

  • Chemistry - ,

    first answer isnt redox, second one isnt calcium, third is for sure pb.

    this is difficult because it doesnt match up to reading, webworks are starting to get unreasonable.

  • Chemistry - ,

    1. reduction

    2. Pb^2+

    3. Pb

  • Chemistry - ,

    1. reduction
    2. Pb^2+
    3. Pb

  • Chemistry - ,

    UCI girl is right

  • Chemistry - ,

    uci girl is right
