Indicate whether it occurs at the cathode or anode, tell if each is voltaic or electrolytic cell.?
(A) For each half-reaction, indicate whether the reaction occurs at the cathode or the anode. Assume it is a voltaic (galvanic) cell. (1) Sn -> Sn+2 + 2e- (2) Cu+2 + 2e- -> Cu (3) Zn -> Zn+2 + 2e- (B) Indicate whether the item in the list describes a voltaic cell or a electrolytic […]
A steady current of 1.00 amperes is passed through an electrolytic cell AgNO3…?
Question: A steady current of 1.00 ampere is passed through an electrolytic cell containing a 1 molar solution of AgNO3 and having a silver anode and a platinum cathode until 1.54 grams of silver is deposited. (a)How long does the current flow to obtain this de¬posit? (b)What weight of chromium would be deposited in a […]
Is a fuel a Voltaic cell or an Electrolytic cell?
In electrolytic cell, current of 4A is passed thru XCl for 20 min, and made 1.15g of metal X. What is X?
In an electrolytic cell using inert electrodes, a current of 4.00 A is passed through a molten binary salt with the formula XCl for 20.0 minutes. 1.15 g of metal X is produced at the cathode. What is the metal X? (a) Li (b)Na (c)K (d)Rb (e)Cs I tried to use ne=IT/F with F=9.65×10^4 c/mol, […]
galvanic or electrolytic cell??
in which type is it neccesary to keep the reactants separate and why??…what are the two key differences between the two cells?
Does an ELECTROLYTIC CAPACITOR store electricy when in an DC circuit only?
I have an HID xenon conversion kit installed in my motorcycle.. I hope to save electricity of my battery by having a capacitor. Does it help conserve electricity? I mean the does the capacitor conserve electricity when i’m using my HID Xenon bulb?
Electrolytic cell (finding time)?
an electrolytic cell is used to plate silver from a silver nitrate solution onto an electrode. How much time (in seconds) is required to deposit 8.0g of silver if the current is kept constant at 5.0 amperes? Assume 100% current efficiency (F=96480C/mole-)
How do ultra capacitors work? How are they different from electrolytic capacitors?
Also id like to know how ultracapacitors compare with fuel cells, also what specific applications do ultracapacitors have in the automobile industry. Thank you
Electrolytic Cell help?
Draw and label an electrolytic cell suitable for electrolysing molten CaCl2. Write down the anode and cathode reactions, and specify the products of the electrolysis. Would it be possible to obtain calcium metal from the electrolysis of aqueous CaCl2? Explain. — Now this is what I’ve got so far: (Ca^2) calcium ions migrate towards the […]
AP Chem free response question about electrolytic cell?(please help)?

If a question says electrochemical cell, how do you know if the two half rxns are for electrolytic or galvanic
So if they give you two half rxn, and it says they are an electrochemical cell, how do you know if it is electrolytic (therefore -E total), or should be the opposite (+) E total?
