    I got some Chemistry homework from school today and I wanted to start it now as i'm away at the weekend so I won't have any time to do it.

    My Homework is about balancing equations.

    I have done it but I'm not sure about what I have put for the balanced equation of Thermal Decomposition


    This is the equation:
    CaCo3 --- CaO + Co2

    Here is what I got for the balanced symbol equation:
    5CaCo3 --- 5CaO + 5Co2

    Is this right. Please help.

    Why add the 5's? Equation balanced already.
