1,2-Dichloroethane is a volatile organic compound that was once added to gasoline along with the heavy metal lead. At many former gasoline storage sites, the unsaturated soil and groundwater are still contaminated with 1,2-dichloroethane. One of the concerns with volatile organic compounds in the unsaturated zone of soil is that they can diffuse into buildings and contaminate the air. Calculate the concentration of 1,2- dichloroethane in air that will result in a carcinogenic risk of 104, based on a breathing rate of 11.3 m³/d, exposure for 10 hours per day, and an inhalation PF of 9.1x10-² kg•d/mg. Express your answer in µg/m³. A.

A buffer system works to keep pH within a narrow range. Buffer systemsare critical in all living cells/tissues. If pH were to measurably shift in a cell,what category of biological molecules would be most impacted, andwhat term refers to the resulting loss of their functional shapes? A buffer is a substance that, when it ionizes in water, creates a buffersystem. The substance and one of its ions represent a weak acid and aweak base. These form a pH-controlled equilibrium. Based on thedefinitions of acid and base, if [H+] increases, which would combine withthe H+, preventing a pH shift? If [H+] decreases, whichwould release H+ to counter a pH change? Check the one characteristic below that is important in a buffer system. maintains a neutral pH prevents pH from dropping prevents pH from rising minimizes change in p
A solution of sodium acetate is prepared using 0.56 mol L-1 NaOH as the solvent. The pKapKa of acetic acid is 4.75 . The concentration of sodium acetate after mixing, before any reaction takes place is 0.44 mol L-1 . Calculate the equilibrium concentrations of all acid species: [ CH3COOH ], [ CH3COO- ], the pH and the pOH in the solution. Some assumptions may not work, on the other hand, if you do not make the correct assumptions first, the quadratic formula will give you the wrong answer.
