Balancing equations

  1. Nov 7, 2008 #1
    1. The problem statement, all variables and given/known data

    Cu(NO3)2(aq) + Na2CO3(s) + H2O -> CuCO3*Cu(OH)2(s) + NaNO3(aq) + CO2(g)

    CuCO3*Cu(OH)2(s) + Heat -> CuO(s) + H2O(l) + CO2(g)


    2. Relevant equations


    3. The attempt at a solution

    Cu(NO3)2(aq) + 2Na2CO3(s) + H2O -> CuCO3*Cu(OH)2(s) + 4NaNO3(aq) + CO2(g)

    CuCO3*Cu(OH)2(s) + Heat -> 2CuO(s) + H2O(l) + CO2(g)

    Can anyone help me to balance these 2 equations? I tried but neither one seems to be correct.

    You are very close in the first case (there is not enough copper on the left - you need two atoms, add second molecule of copper nitrate and check if the equation is not already balanced). Also, my bet is that sodium carbonate used is in the form of solution - or even if it is added as solid, it gets dissolved before reacting (so it should be not (s)).

    Second is OK.
