The electrolysis of water produces oxygen and hydrogen gas.
2H2O --> 2H2 + O2
The blue substance left in the solution after electrolysis with copper electrodes in a sodium carbonate solution is likely copper(II) carbonate. This forms as a solid product of the reaction between the copper electrode and the carbonate ions present in the solution.
During electrolysis of copper sulfate solution using copper electrodes, the blue color of the solution remains because copper ions from the copper sulfate solution plate onto the cathode, replacing the copper atoms in the electrode. This does not change the color of the solution as the copper ions remain in solution, maintaining the blue color.
Water is not used in the electrolysis of copper permanganate solution because water will compete as an electrolyte and interfere with the desired redox reactions happening at the electrodes. Using water as an electrolyte would form other byproducts instead of the intended products of the copper permanganate electrolysis. This could lead to inefficient and unpredictable results in the process.
The balanced equation for the reaction between aluminum and copper oxide is: 2Al + 3CuO → 3Cu + Al2O3. This reaction produces copper and aluminum oxide.

Electrolysis
Factors that can affect the electrolysis of molten copper chloride include the current applied, the concentration of copper ions in the electrolyte, the temperature of the electrolyte, and the composition of the electrodes used in the electrolysis process. Additionally, factors such as the purity of the copper chloride and the presence of impurities in the electrolyte can also impact the efficiency of the electrolysis process.

Inert electrodes simply serve as electrical conductors and are unchanged by the cell processes. Active electrodes change during the cell reactions. An example of inert electrodes is platinum in the electrolysis of water. The platinum remains unchanged and the water is split into hydrogen and oxygen. An example of active electrodes is in the electrolysis of copper sulfate solution with copper electrodes. The anode copper is converted into copper ions in the solution, and metallic copper builds up on the cathode. The term active electrode is also used in eeg measurement, here as the opposite to passive electrode. Electrodes are the pads attached to the skin to get readings, and active ones don't need a conductive paste to get a good signal.

Copper cloride is the word equation for copper and clorine hope this helps:)
The balanced equation for the reaction between aluminum and copper oxide is: 2Al + 3CuO → 3Cu + Al2O3. This reaction produces copper and aluminum oxide.

Then use electrolysis to transfer all the copper from the impure anode to the cathode.
The chemical formula (not equation) of copper(II) sulfate is CuSO4.
Copper oxide (CuO) reacts with hydrogen gas (H2) to form copper (Cu) and water (H2O). The word equation for this reaction is: copper oxide + hydrogen gas → copper + water.
