Using standard reduction potentials from the ALEKS Data tab, calculate the standard reaction free energy ΔG0 for the following redox reaction. Be sure your answer has the correct number of significant digits.

Engineer, During the transmission of electricity over long distances, an alternating current is passed over aluminium cables at high voltages and low current. .i) Give two reasons why is alternating current  (a.c) used in preference to direct current (d.c) ?. ii) Give two reasons why are aluminium cables preferred to copper for long distance transmission of electricity?

Two 1.6 kg masses are 1.0 m apart (center to center) on a frictionless table. Each has +10 μC of charge.

(a) What is the magnitude of the electric force on one of the masses?

(b) What is the initial acceleration of the mass if it is released and allowed to move?

An electron experiences an initial acceleration of 1.80 x 10⁵ m/s² east when placed a certain distance from a +2.00 µC charge. Determine the magnitude of the electric field at the point where the electron was placed.
