SUMMARY
The discussion focuses on balancing two chemical equations involving copper nitrate (Cu(NO3)2), sodium carbonate (Na2CO3), and copper carbonate hydroxide (CuCO3*Cu(OH)2). The correct balanced equation for the first reaction is Cu(NO3)2(aq) + 2Na2CO3(s) + H2O -> CuCO3*Cu(OH)2(s) + 4NaNO3(aq) + CO2(g). The second reaction is correctly balanced as CuCO3*Cu(OH)2(s) + Heat -> 2CuO(s) + H2O(l) + CO2(g). Key insights include the need for two copper nitrate molecules to balance the first equation and the assumption that sodium carbonate is likely in solution.
