complete and balance the following decompition equations

CaCO (heated) -->
3

please tell me how to do this and what exactly is suppose to be going through my head while doing this. I can balance these equations with no problem I just have no idea what to do...

  • Chem -

    Caronates when heated give off carbon dioxide and the metal oxide.

  • Chem -

    so wat do i do?

  • Chem -

    so you write the formula for calcium oxide (CaO) and carbon dioxide (CO2).
    CaCO3 ==> CaO + CO2
    What's going on? You need to recognize that carbonates, when heated, give off the metal oxide and CO2, write those products, then balance the equation.
