  2. Hint:
    If call the metal, M, and the anion, X, then MX ==> M + X

    Does this look like an acid base reaction to you. Not to me.
    It might be reduction.
    It might be oxidation.
    It CAN]T be fusion (since they are coming apart, not being fused.)
    It CAN'T be sublimation because there is no vapor there. So look at the oxidation states and figures if its B or C.

  3. I left out this with the problem

    Ni2+(aq) + 2e¨C ¡ú Ni(s) ¨C0.25 V
    Sn4+(aq) + 2e¨C ¡ú Sn2+(aq) +0.15 V
    Br2(l) + 2e¨C ¡ú 2Br¨C(aq) +1.07 V

    so it says:
    Which process represents a general method for the preparation of a metal from its
    compounds? .
    (A) neutralization (D) fusion
    (B) reduction (E) sublimation
    (C) oxidation
    Then this
    Ni2+(aq) + 2e¨C ¡ú Ni(s) ¨C0.25 V
    Sn4+(aq) + 2e¨C ¡ú Sn2+(aq) +0.15 V
    Br2(l) + 2e¨C ¡ú 2Br¨C(aq) +1.07 V

    Sorry about that

  4. My screen doesn't tell me much. I have gibberish between the 2e and the metal for each of them.
