Chemistry Correspondace help!

  1. Jul 9, 2007 #1
    hey! i need real bad on a few questions, i havent taken grade 11 chem, but im on to 12 (circumstances) so please explain simply as possible.
    1) Write equations for the neutrilization reactions that result in the formation of the following salts
    a)Lithium Carbonate
    b)Copper(II) chlorate
    c)Aluminium Sulphate
    d)Ammonium Iodide

    ** i have honestly no idea what to do, all i have is the compounds!

    2) For each situation, identify for which a reaction is most like to occur. If a reaction does, write a net ionic equation.
    a) Chronium into silver nitrate
    b) Gold in hydrochloric acid
    c) Nickel Pellets in calcium acetate, Ca(CsH3O2)2.
    d) Aluminum into sulphuric acid
    e) Zinc into lead (II) nitrate

    i think that c, d and e react together, and that a and b do not.. not sure though!
    i also have no idea how to get the ionic equation.. PLZ help!!

    You are asked to find two reagents that are an acid and a base. The neutralization produces the salts given in a-d.

    eg... If you were given NaCl, the answer would be:
    NaOH + HCl ----> NaCl + H2O

    for 2) you should be knowing that a more reactive metal will displace a less reactive one from its salt. Have a look at the reactivity series from this link:
    http://en.wikipedia.org/wiki/Reactivity_series

    take Magnesium and Zinc Chloride as example. Magnesium is more reactive than zinc. Hence it will displace the Zn2+ ion from Zinc Chloride and Magnesium Chloride will be formed.

    full equation: Mg(s) + ZnCl2(aq) ------> MgCl2(aq) + Zn(s)
    ionic Equation: Mg(s) + Zn2+(aq) ------> Mg2+(aq) + Zn(s)
