The annual production of Cl2 is about 45 millions tons per year. Assume that a typical plant is operational 90 % of the year. The operating voltage of a cell is 3.4 V (considerably higher than the equilibrium voltage). Required:
a. Write down the half-cell reaction for the oxidation chloride to form chlorine.
b. Determine the total current worldwide needed to gener- ate the global supply of Cl2.
c. Calculate the electrical power needed to produce the global supply of chlorine using electrolysis.

good for her? ? where is the question?

the first american roller coaster was the mauch chunk switchback railway, built in the mountains of pennsylvania in the mid-1800s. the track, originally built to send coal to a railway, was reconfigured as a "scenic tour."

see the picture for the vector

the magnitude of the vector by pythagorean theorem

r = √( (-10)^2 + (3)^2 ) = √109

magnitude = √109 units

the direction angle between vector and x-axis is

tan^(-1)(3/10) = 16.699

so the direction is approximately 16.7 degrees north of west
