Title: are these equations correct?
Post by: jennielynn_1980 on June 01, 2006, 01:27:32 PM

I was given the names and I had to come up with the formula's and reactions.  How do they look?

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 + mercurous nitrate --> 
   2Zn + Hg₂Cl₂ --> 2Hg + ZnCl₂

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

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

f) ferrous bromide + phosphoric acid -->
   3FeBr₂ + 2H₃PO₄ --> 6HBr + Fe₃(PO₄)₂

g) the complete combustion of ethene C₂H₄-->
     C₂H₄ + 3O₂ --> 2H₂O + 2CO₂

h) calcium carbonate + hydrobromic acid -->
    CaCO₃ + 2HBr --> CaBr₂ + CO₂ + H₂0

I seriously don't want this to become a homework check website. So please keep these kinds of posts to a minimum.

They all seem correct.

Sorry  :-[  Since it is a homestudy course I don't have a class to check them in.  I will find another way.  My apologies.

I don't see any nitrate....

True.  :-[

Still, the chemical equations are properly balanced, aren't they?

Oops, I must have read it as chloride because both answers on either side contain chloride. *smacks forehead*
