Two tiny conducting spheres are identical and carry charges of -18.8 µc and +46.5 µc. they are separated by a distance of 2.47 cm. (a) what is the magnitude of the force that each sphere experiences, and is the force attractive or repulsive? n

Acertain half-reaction has a standard reduction potential e_red^0 = -0.94 v. an engineer proposes using this half-reaction at the cathode of a galvanic cell that e must provide at least 1.00 v of electrical power. the cell will operate under standard conditions. a. is there a minimum standard reduction potential that the half-reaction used at the anode of this cell can have? b. is there a maximum standard reduction potential that the half-reaction used at the anode of this cell can have?
