A hypothetical Fresnium (Fn) is placed in a solution of 1 M fresnium nitrate, and a standard copper reference electrode is also placed in the solution. In order to get a positive voltage reading, the copper electrode must be connected to the-pole of the voltmeter, and the fresnium metal to the + pole. The voltage meter reads +0.63 volts. Write out the reaction equation, and then calculate the standard reduction potential of Fresnium.
