6) A cloud droplet at 5 km (P = .54 atm) absorbed sulfur while in equilibrium...
(8 pts) Carbon dioxide in the atmosphere dissolves in water to establish an equilibrium that can increase the acidity of aqueous solutions in the environment. This equilibrium is CO2(g) = CO2 (aq), Kn= 3.1 x 10-2 at 25°C. Kh is called the Henry's law constant, which relates the solubility of the gas CO2 in the aqueous solution, [CO2), to the partial pressure of CO2 over the solution, p(CO2): [CO2] (M)= Kn · p(CO2) (atm) During the preceding decades, the atmospheric...
6. Given a total dissolved lead concentration of 2.0x10-5 M, a total dissolved NTA concentration of 2.0x10-2 M, and a pH of 12.3 (note extreme pH) a. Under these conditions, what is the dominant form of NTA? b. Write an equation for total dissolved NTA and for total dissolved Pb. What assumptions can you make? c. Calculate the predicted [Pb2+], considering NTA complexation only? d. What is the [Pb2+] as predicted by the solubility of Pb(OH)2(s) at pH 12.3? e....
(6 pts.) 1. The air pressure in the inner tube of a tire on a typical racing bike is held at a pressure of 115 psi (pounds! per square inch). Convert this pressure to atm and mm Hg. (3 pts. each) The atmospheric pressure is 0.978 atm. Determine the pressure of the enclosed gas in each of the cases depicted below. Gas Gas (6 pts.) 3. A 5.90 L bottle contains 1070 g of oxygen at 25.0°C. Calculate the pressure...
5. What was the purpose of the NaNO3 solution in this experiment? 6. Could a solution of NaCl be used instead of NaNO3? 7. What was the purpose of FeSO4 solution in this experiment? 8. Could a solution of FeCl, be used instead of FeSO4? 9. Could a solution of NaSO4 be used instead of FeSO4? 10. Calculate the standard cell potential for the spontaneous redox reaction between a Pb(s)/Pb(NO3)2(aq) half-cell and a Ag(s)/AgNO3(aq) half-cell. Which metal would be oxidized?...
