The preparations of two aqueous solutions are described in the table below. For each solution, write the chemical formulas of the major species present at
equilibrium. You can leave out water itself.
Write the chemical formulas of the species that will act as acids in the 'acids' row, the formulas of the species that will act as bases in the 'bases' row, and the
formulas of the species that will act as neither acids nor bases in the 'other' row.
You will find it useful to keep in mind that NH, is a weak base.

During a panic attack, a person
hyperventilates (exhaling more CO2(g)
than normal. Will this chemical equilibrium
shift? If so, in what direction? Will the
blood pH stay the same, increase, or
decrease? Justify your reasoning and
draw a concentration-time curve that
represents this change.

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 m/d, exposure for 10 hours per day, and an inhalation PF of 9.1x102 kg•d/mg. Express your answer in µg/m³. А. Calculate the concentration of 1,2-dichloroethane in groundwater that will result in a hazard quotient of 1, based on drinking 2 L of water per day for a lifetime and an oral RfD of 0.012 mg/(kg d). Express your answer in ppb. В.arrow_forward
