Quick Check: Balancing Chemical Reactions

[J_o_S]

Hi, I'm pretty sure I have the idea here. but can i just get a "looks good" from someone?

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

CaCO_{3}+2HBr\rightarrow CaBr_{2}+H_{2}CO_{3}

Daniel.

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