Homework Help: Chemistry - Reactions - Gas given off and solid remaining after heating

  1. Feb 2, 2010 #1
    1. The problem statement, all variables and given/known data
    If the following substances were heated what gas would be given off and what solid would remain? strontium carbonate, zinc carbonate, and iron carbonate.


    2. Relevant equations
    N/A

    3. The attempt at a solution
    So I presume carbon dioxide would be given off and the 3 substances would become oxides. I'm don't get what would form a solid though?

    The oxides would form the solid. To find the oxides, just remove CO2 from the empirical formula.

    So all the oxides would be solids? I thought it might be that... but the way the question was presented made me think it would just be one.
