Toluene has contaminated a city's drinking water supply. An activated carbon system will be designed to remove toluene to below regulatory levels. If equilibrium is achieved between activated carbon and aqueous-phases and the concentration of toluene in the aqueous-phase is 0.010 mg/L, what will be the concentration of toluene sorbed to the activated carbon? The Freundlich parameters for toluene and the particular type of activated carbon are: K= 159 mg/g (L/mg)^1/n = 0.54. Express your answer in units of mg...

Water flows at 20 cm3/sec through a long straight tube that has an inner diameter of 1 cm. As the water flows, a toxin leaches from the tube into the water. At the inner surface of the tube, the toxin attains its saturation concentration, Csat = 2 mM. Fortunately, upon entering the water the toxin also irreversibly degrades into a non-toxic compound; this degradation follows first-order kinetics. Toxin Diffusivity D = 10-5 cm2/sec Toxin mass transfer coefficient k = 1.38...

A contaminant degrades at a rate o f0.0035 min-1. The initial concentration is 1.5 mg/L. The regulatory limit is 1ppb. a. Find the half-life of the contaminant. b. Find the concentration of the contaminant one hour after the reaction started. c. How long will it take until the contaminant reaches the regulatory limit?

The integrated rate law allows chemists to predict the reactant concentration after a certain amount of time, or the time it would take for a certain concentration to be reached. The integrated rate law for a first-order reaction is: [A]=[A]0e−kt Now say we are particularly interested in the time it would take for the concentration to become one-half of its initial value. Then we could substitute [A]02 for [A] and rearrange the equation to: t1/2=0.693k This equation calculates the time...

6. (1) A water treatment plant applies chlorine for disinfection so that 10 mg/L chlorine is achieved immediately after mixing. The volume of water treated each day is 25,000,000 gal. What is the mass of chlorine needed by this plant every day? (2) The disinfection takes place in a contact tank which is a CSTR at steady state. Chlorine concentration in the contact tank is constant at 3 mg/L. Effluent of this contact tank will enter drinking water distribution systems...

If you start with 0.350 mol of dinitrogen pentoxide in a 2.0 L volume, how many miles will remain after 10 minutes? How long will it take for you to have 0.125 moles of reactant left? What is the half-life of dinitrogen pentoxide?" *Please show all work. * if it's out of...

1) Use Henry's law to determine the molar solubility of helium at a pressure of 1.9 atm and 25 ∘C. Henry’s law constant for helium gas in water at 25 ∘C is 3.70⋅10−4M/atm. 2) A 2.800×10−2M solution of NaCl in water is at 20.0∘C. The sample was created by dissolving a sample of NaCl in water and then bringing the volume up to 1.000 L. It was determined that the volume of water needed to do this was 999.2 mL...
