Question

A voltaic cell is constructed in which the anode is a Zn Zn²+ half cell and the cathode is a H, H+ half cell. The half-cell compartments are connected by a salt bridge. (Use the lowest possible coefficients. Use the pull-down boxes to specify states such as (aq) or (s). If a box is not needed, leave it blank.) The anode reaction is: The cathode reaction is: The net cell reaction is: In the external circuit, electrons migrate - Vthe Zn|Zn²+ electrode C V the H2/H* electrode. In the salt bridge, anions migrate the Zn/Zn2+ compartment - the HHcompartment.
The answer for last 2 parts should be either (from and to) or (to and from)

Answer 1

# Anode : 20/2n2+ Half cen cathole: H2 1H+ half ceu The Half cell compartments are connected by a Salt bridge: o Oxidation occurs at anode & Reduction occurs at Cathode. The anode reaction 13 → 2n(s) –> En att + 2e Oxidation The cathode reaction is → 12 Hyde) + 24 --> H2 (8) Reduction - The net cell reactim is> 2n 6+ 2H+64 -> 2nat+ H20) Ogn the external circuit electrons migrutes from the 2n/2n 27 electrode to the H2/H+ electrode On the salt bridge anion migrate to the 20/2n2+ compartment from the H7H* compartment # Anode: cr lcp 3t halt cell Cathode: F1 F2 halt cell The Halt-ceu compartments are connected by a 1 salt bridge A The anode reaction is → cris) -> cr gert 3e x2 2Cr (3) → 2Creet+ 6el Oxidation

The cathode reaction By F2 (g) +20 3F2 (g) +60 > 2F Part →6 F(aq) --X3 Reduction - The net cell reaction is 26r(3) +372(8) ► 2Cr3+(22) + 6F (aq)] o 9n the external efrcuit, eletron migrates to the FuFz electrode from the cr/Cr3+ electrode In the salt bridge, anim migrates from the Fultz electrodė ito! the erlCr3+ compartment. NOTE ; On external circuit, electrons migrates from 9n salt bridge, anih migrates from Anode to cathode. - cathode to anode.
