Here are the homework questions, I tried but I think I still have most of them wrong.
[b]Write and balance equations for the following reactions:[/b]
a) [b]zinc sulphate + barium nitrate[/b] --->
b) [b]gold (III) sulphate + barium chloride[/b] --->
c) [b]zinc + mercurous chloride[/b] --->
d) [b]tin + antimony (v) chloride[/b] --->
e) [b]calcium + water[/b] --->
f) [b]ferrous bromide + phosphoric acid[/b] --->
g) [b]the complete combustion of ethene, C2H4[/b] --->
h) [b]calcium carbonate + hydrobromic acid[/b] --->
I did the following:
a) ZnSO4 + Ba(NO3)2 ---> Zn(NO3)2 + BaSO4
b) Au2(SO4)3 + 3BaCl2 ---> 3BaSO4 + 2AuCl3
c) 2Zn + Hg2(NO3)2 ---> 2Hg + ZnNO3
d) 5Sn + 2SBCl5 ---> 2Sb + 5SnCl2
e) Ca + 2H2O ---> Ca(OH)2 + H2
f) FeBr2 + H3PO4 ---> H2O + ?
g) C2H4 + 3O2 ---> 2H2O + 2CO2
h) CaCO3 + HBr ---> H2O + ?
I have no idea if these are right, as Im still learning on my own. Reactions really seem to confuse me. Anyways, any help with these, the ones that are right, which are wrong is appreciated.
