Identify the substances N, Q, the gas from step II, S, I, P, the white solid from step VI, the white precipitate from step VII, and mixture M in the flowchart.

Here are the formulas for the substances identified in the flow chart:

• Solid N: $\boxed{\text{CuCO}_3}$ (Copper(II) carbonate)
• Black solid Q: $\boxed{\text{CuO}}$ (Copper(II) oxide)
• Gas (from Step II): $\boxed{\text{CO}_2}$ (Carbon dioxide)
• Blue solution S: $\boxed{\text{CuSO}_4}$ (Copper(II) sulfate)
• Deep blue solution I: $\boxed{\text{[Cu(NH}_3)_4]^{2+}}$ (Tetraamminecopper(II) ion, in solution)
• Solution P: $\boxed{\text{ZnSO}_4}$ (Zinc sulfate)
• White Solid (from Step VI): $\boxed{\text{BaSO}_4}$ (Barium sulfate)
• White precipitate (from Step VII): $\boxed{\text{Zn(OH)}_2}$ (Zinc hydroxide)
• Mixture M (the two salts): $\boxed{\text{CuCO}_3 \text{ and } \text{ZnSO}_4}$
