2 Al₂O₃ = 4 Al + 3 O₂
4 moles Al ----------> 3 moles O₂
11.0 moles Al -------> ?
O₂ = 11.0 * 3 / 4
= 8.25 moles of O₂
hope this helps you and have a great day!
Answer:
so
Explanation:
so what i should do any way thanks for the points
Reduction
Explanation:
At the cathode, the copper electrode will be reduced and probably discharged if is preferentially selected based on the activity series of elements.
- In an electrolytic cell, reduction occurs at the cathode and oxidation reaction occurs at the anode.
- The discharge of ions at electrodes involves the a gain of electrons called reduction at the cathode
- At the anode, a loss of electrons occurs and this process is called oxidation.
- Making the copper the cathode electrode in this cell, ensures that it undergoes reduction.
