CALCULATIONS: BALANCE the following equations. Write the names of the reactant(s) and product(s) below the substances for each reaction. 1. 2 Cu(s) + O2(g) ----> 2 CuO(s) Copper+Oxygen Copper Oxide 2. 2 Mg(s) + O2(g) -----> 2 MgO(s) Magnesium+Oxygen Magnesium Oxide 3. Na2CO3(s) -----> Na2O(s) + CO2(g) (balanced) Sodium Carbonate Sodium+Carbonate 4. Zn(s) + 2 HCl(aq) ----> ZnCl2(aq) + H2(g) Zinc+Hydrochloric acid Zinc Chloride+Hydrogen 5. Mg(s) + CuSO4(aq) ----> MgSO4(aq) + Cu(s) (balanced) Magnesium+Copper Sulfate Magnesium Sulfate+Copper 6. 3 Zn(C2H3O2)2 + Na3PO4 ---> 3 NaC2H3O2 + Zn3(PO4)2 Zinc Acetate+ Sodium Phosphate Sodium Acetate+ Zinc Phosphate 7. 3 NaHCO3 + 3 HCl ----> H2CO3 2 [(H2O + CO2)] + 3 NaCl Discussion The lab was fairly simple. My lab partners split up the work so we were able to finish the lab quickly. However, we had a few problems. 1) It was difficult to burn the Magnesium and observe it without hurting your eyes. As possible solution for this would be to maybe wear
