What is the balanced equation for copper (I) oxide and Aluminum?
Copper(I) oxide is a solid and so is aluminum. Any reaction that might occur would have to be at an elevated temperature. This is a thermite reaction in which copper(I) is reduced to copper metal (molten) and aluminum is oxidized to aluminum oxide. 3Cu2O(s) + 2Al(s) -- 6Cu(s) + Al2O3(s) ========= Follow up ========== Do you mean in aqueous solution? There won't be any copper(I) chloride in aqueous solution. CuCl is very insoluble in water, but will undergo disproportionation to form Cu2+ ions and copper metal. Therefore, you would actually have a solution of copper(II) chloride. Copper(II) chloride will react with aluminum to form copper metal and aluminum ions. Ordinarily aluminum won't react with copper(II) ions. The reaction does proceed in the presence of chloride ion. This is because the chloride ion will react with the Al2O3 layer on the surface of aluminum metal to make [AlCl4]^- which exposes the aluminum metal below, and thus a reaction can occur. 3Cu2+ + 2Al(s) -- 2Al3+ + 3Cu(s)
