In addition to mass balance, oxidation-reduction reactions must be balanced such that the number of electrons lost in the oxidation equals the number of electrons gained in the reduction. This balancing can be done by two methods: the half-reaction method or the oxidation number method. The half-reaction method balances the electrons lost in the oxidation half-reaction with the electrons gained in the reduction half-reaction. In either method H2O(l), OH?(aq), and H+(aq) may be added to complete the mass balance. Which...

ANSWER ALL PLEASE
Question 43 2 pts The rms voltage across and the rms current through a single circuit element connected to an ac generator are, respectively, Vrms = 131 volts and Ims = 37 A. The angular frequency of the generator id w = 78. It is observed that the current leads the voltage by 90°. The element that is connected to the ac generator is either a capacitor, an inductor, or a resistor (only one of the three)....
