I got wrong answer from the first pic and i don't know why. Kindly answer the second picture that does not have a answer. Thank you!
Transcribed Image Text:Enter electrons as e".
Use smallest possible integer coefficients for ALL reactions.
If a box is not needed, leave it blank.
A voltaic cell is constructed in which the following cell reaction occurs. The half-cell compartments are connected by a salt bridge.
3B12(1) + 2A1(s) → 6Br (aq) + 2A13*
*(aq)
The anode reaction is:
2Al(s)
2A1³* (aq) x

6Br (aq)
In the external circuit, electrons migrate to
v x the Al|AP* electrode from
v x the BrBr, electrode.
In the salt bridge, anions migrate to
v x the Br"|Br2 compartment from
v x the Al|AIS* compartment.
