Step 1: “Colorless nitric acid is added to solid orange-brown copper powder, resulting in a blue-green solution, a brown gas, and liquid water.”
HNO is added to Cu, resulting in Cu(NO3)2(aq) and NO2 and H2O.
The copper atoms are in Cu(NO3)2(aq)/Copper(II) Nitrate. The copper is in compound form.
Step 2: “Clear, colorless sodium hydroxide solution is added to the blue-green solution, resulting in clumps of dark blue solid and clear, colorless sodium nitrate solution.”
NaOH(aq) is added to Cu(NO3)2(aq), resulting in Cu(OH)2(s) and Na(NO3).
The copper atoms are in Cu(OH)2(s)/Copper(II) Hydroxide. The copper is in compound form.
Step 3: “The dark blue clumps are heated, resulting in a black solid and liquid water.”
Cu(OH)2(s) is heated, resulting in CuO(s) and H2O.
The copper atoms are in CuO(s)/Copper(II) Oxide. The copper is in compound form.
Step 4: “Clear, colorless sulfuric acid is added to the black solid, resulting in a clear blue solution and liquid water.”
H2SO4(aq) is added to CuO(s), resulting in CuSO4(aq)and H2O.
The copper atoms are in CuSO4(aq)/ Copper(II) Sulfate. The copper is in Compound form.
Step 5: “Solid, silver-gray zinc is added to the clear blue solution, resulting in a brownish powder and clear, colorless zinc sulfate solution.”
Zn(s) is added to CuSO4(aq), resulting in ZnSO4 and Cu(s).
The copper atoms are in Cu(s)/Copper. The copper is in elemental form.
Part 3: Transcribing the words into balanced chemical equations with formulas. Write the balanced chemical equation for the reaction occurring during the step, include the states of matter.
