# A student is given 1.525 g of pure CuO. To recover the Cu present in the compound, the dark powdery solid was dissolved in 15.0 mL of 6 M HCl, the solution diluted with 50.0 mL of water, and 0.50g of Mg was added. was this enough Mg to displace all the Cu2+ ions from the solution? A. If there is not enough Mg present, how much more Mg metal would be needed (Minimum)? B. If there was enough Mg to displace the Cu, how much 6 M HCl (in mL) would be required to decompose the excess Mg present?
