Quick Check

  1. Jun 14, 2005 #1
    Hi, I'm pretty sure I have the idea here. but can i just get a "looks good" from someone? :smile:

    Write and balance equations for the following reactions:
    a) zinc sulphate + barium nitrate →
    ZnSO4 + Ba(NO3)2 --> Zn(NO3)2 + BaSO4


    b) gold (III) sulphate + barium chloride →
    Au2(SO4)3 + 3BaCl2 --> 3BaSO4 + 2AuCl3


    c) zinc + mercourous nitrate →
    Zn + HgNO3 --> Hg + Zn(NO3)

    d) tin + antimony (V) chloride →
    5Sn + 2SbCl5 --> 5SnCl2 + 2Sb


    e) calcium + water →
    Ca + 2H2O ---> Ca(OH)2 + H2

    f) ferrous bromide + phosphoric acid →
    3FeBr2 + 2H3PO 4 --> 6HBr + Fe3(PO4)2


    g) the complete combustion of ethane, C2H4 →
    C2H4 + 3O2 --> 2CO2 + 2H2O


    h) calcium carbonate + hydrobromic acid →
    CaCO3+ 2Hbr --> Ca(BrO3)2+ H2CO3


    Thanks for your time

    The last (h)) should be,of course

    [tex] CaCO_{3}+2HBr\rightarrow CaBr_{2}+H_{2}CO_{3} [/tex]

    Daniel.

    P.S.You may also write ...+H_{2}O+CO_{2}
