The world needs a new source of energy, an unspillable source.

Electrolytic Cells problem?

1. Aluminum is manufactured by the Hall-Heroult Process which produces aluminum from aluminum oxide in an electrolytic cell. The net reaction is: Al3+ + 3e- –> Al(s) You need to design a cell that will produce Al at the rate of 1 kg per hour. How many amps must your power supply produce? …Is 1984 […]

Chemistry help, please! Electrolytic cells!?

In an electrolytic cell, Cu2+ will A- Migrate to the negative electrode B- Be reduced at the positive electrode C- Migrate to the positive electrode. D- be reduced at the negative electrode. Thanks in advance.

Help with electrolytic cells ?

what does it mean that the ions go against a gradient ? the anions are still going towrds the anode and the cations still towards the cathnode. and why do we need an external battery i know the reaction is not spontaneous but why? is it because of the gradient? but what causes the gradient […]

Electrolytic and Galvanic Cells? – plz help!!?

Electrolytic and Galvanic Cells? Two half cells in a galvanic cell consists of one iron (Fe(s)) electrode in a solution of iron(II) sulphate (FeSO4(aq)) and a silver (Ag(s)) electrode in a silver nitrate solution. a) Assume that the cell is operationg as a galvanic cell. State the oxidation half-reaction, the reduction half-reaction, and the overall […]

Electrolytic Cells + Amperes?

Commercial electrolytic cells for producing aluminum operate at 5 volts and 100,000 Amperes. How long does it take to produce 1000 kilograms of aluminum? If electricity costs 9 cents per kilowatt hour, what is the cost of producing exactly 1 pound of aluminum?

electrolytic cells? fuel cells? confused!?

So, im writing a research paper and i did some research on hydrogen use in fuel cells. But i’m confused. What exactly is a fuel cell and what is it used for? and is it the same as an electrolytic cell? whats that? thank you so much for any answers. my confusion is getting frustrating
