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

    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.
