Homework Help: 3 Chem Equations

  1. Jan 3, 2006 #1
    I need to include net ionic eq, phase symbols, etc.
    1. Sulfur trioxide is heated with carbon dioxide.
    2. A solution of strontium chloride is mixed with a solution of sodium sulfate.
    3. Hydrochloric acid is added to sodium hydroxide

    My work:
    1. SO3(g)+H2O(l)---->H2SO4(aq)
    2. Sr^{2+}(aq)+SO4^{2-}------> SrSO4(s)
    3. HCl(aq)+NaOH(aq)------->H2O(l)+NaCl(aq)

    Are these right? Any corrections?

    carbon dioxide?

    the first one is def. wrong. where did u get H20 as a reactant? the original problem states "Sulfur trioxide is heated with carbon dioxide." Re-work the first one, and for a hint, there will be no net ionic reaction for this one b/c nothing is in solution.

    the second one is right. the overall is SrCl2 + Na2SO4 ---> SrSO4 + 2 NaCl, and the net ionic reation you have looks good.

    the third on looks ok, but im not too sure. that chemistry is now buried under a semester of organic chem, so forgive me if im rusty
