Copper(II) Oxide Reaction
I found everything I needed to do a really cool reaction between copper (II) chloride and aluminum at the hardware store! The copper chloride is made through a double displacement reaction that occurs between solutions of copper (II) sulfate, found in tree root killer, and calcium chloride, a common salt used to melt ice in wintertime. The reaction between copper chloride and aluminum generates hydrogen gas, which is very flammable! The blue green colors you see are the result of electrons in co

SOLVED: 6. Copper(II) oxide reacts with hydrochloric acid toproduce copper(II) chloride and water. How many grams of copper(II)oxide are required for complete reaction with 25.0 mL of 0.103 Mhydrochloric acid? The molar mass of copper(II) oxide is 79.545g/mol. (Hint: start by writing the balanced equation for thereaction.)

SOLVED: When a copper wire is exposed to air at room temperature, it becomes coated with a black oxide, CuO. If the wire is heated above a certain temperature, the black oxide is converted to a red oxide, Cu2O. At a still higher temperature, the oxide coating disappears. Explain these observations in terms of the thermodynamics of the reactions 2 CuO(s) ⟶Cu2O(s) (1)/(2)O2(g) Cu2O(s) ⟶ 2 Cu(s) (1)/(2)O2(g)and estimate the temperatures at which the changes occur.

Copper(II) Oxide Synthesis
The oxidation of copper(II) oxide, CuO(s), to copper(II) oxide, CuO(s), is an exothermic process: 2 CuO(s) O2(g) → 4 CuO(s).The change in enthalpy upon reaction of 35.33 g CuO(s) is -36.05 kJ. Calculate the work, W, and energy change, ΔHrxn, when 35.33 g CuO(s) is oxidized at a constant pressure of 1.00 bar and a constant temperature of 25°C. Note that ΔHrxn is sometimes used as the symbol for energy change instead of ΔHrxn.
