    1. Start with getting the chemical formula of the products.

    Copper(II) nitrate: Cu(NO3)2
    Copper(II) oxide: CuO
    Nitrogen gas: N2
    Oxygen gas: O2

    2. Create an equation with the reactants on the left and the products on the right:



    3. Balance the metals (primary reactants) first. Move down to other reactants putting oxygen and/or hydrogen (if present) last. In this case, Nitrogen then oxygen



    4. If you don't like the fraction (it's not really an error), multiply everything to get it out
