The annual production of cl2 is about 45 million 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). (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.

The melting point of sulfur is 115 °c and its boiling point is 445 °c. what state would sulfur be in at 200 °c?

Lab reagent, hypothesis test.a reference solution used as a lab reagent is purported to have a concentration of 5 mg/dl. six samples are taken from this solution and the following concentrations are recorded: (5.32, 4.88, 5.10, 4.73, 5.15, 4.75) mg/dl.these six measurements are assumed to be an srs of all possible measurements from solution.they are also assumed to have a standard deviation of 0.2, a normal distributin, and a mean concentration equal to the true concentration of the solution.carry out a significance test to determine whether these six measurements provide reliable evidence that the true concentration of the solution is actually not 5 mg/dl.
