How would the aluminum oxide react with copper(II) chloride? Aluminium's oxidative powers are nowhere near that strong. Copper(II) chloride and aluminium oxide do not react with each other; only metallic aluminium beneath the passivisation layer is able to react with copper(II) ions.
Aug 22, 2017 · Explanation: Start with a balanced equation. 2Al + 3CuCl2 → 2AlCl3 +3Cu. Convert 1.35 g Al to moles by dividing by its molar mass, 26.982 g/mol. Since molar mass is a fraction, g/mol, you can divide by multiplying the given mass by the inverse of the molar mass, mol/g . 1.35g Al × 1mol Al 26.982g Al = 0.0500 mol Al.
I am doing a chemistry lab, and for each reaction I need to provide a balanced equation. The reactions are: 1. bare copper wire on a hottest part of a flame held for a few minutes. 2. a nail on a test tube of the solution copper(II) sulfate 3. solid copper (II) sulfate pentahydrate over heat 4. same as number three, but then adding few drops of ...

In this lab experiment, you will react copper (II) chloride and aluminum. You will look for clues as to which substance was in excess and which limited the reaction. Write an investigative question that describes the scientific goals of this experiment. Make sure that your question applies to any reaction.
Dec 04, 2019 · Answer: (i) Copper ions (Cu 2+) and hydrogen ions H + migrate to cathode. (ii) Chloride ions (Cl –) and hydroxyl ions OH – migrate to anode. (iii) Copper ions (Cu 2+) are likely to discharge at cathode, because their position is lower than hydrogen ions H + in electrochemical series. (iv) Cu 2+ + 2e – Cu
A ball of aluminum foil is added to an aqueous solution of copper(II) chloride, which causes an exothermic, single replacement, oxidation-reduction reaction...
