Document Summary
Generates electricity and accumulates electricity reversible chemical reactions a + and terminal flow of electrons to power everything in the car. 6 small energy producing units called cells with 2 sets of electrodes and 8 overlapping metallic plates. Balance the following redox reaction in acidic solution. Summary: balancing redox reactions: assign oxidation states a)determine element oxidized and element reduced, write ox. Redox reactions involve the transfer of electrons from one substance to another. Therefore, redox reactions have the potential to generate an electric current. To use that current, we need to separate the place where oxidation is occurring from the place where reduction is occurring. Current is the number of electrons that flow through the system per second. 1 a of current = 1 coulomb (c) of charge flowing by each second. 1 (cid:373)ole of e = (cid:1013)(cid:1010),(cid:1008)(cid:1012)(cid:1009) coulo(cid:373)(cid:271)s of (cid:272)harge. 1 a = 6. 242 x 1018electrons per second.
