(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...

1. Zinc has been heavily used in the metal finishing industry and the typical wastewater from this industry contains Zn". When this untreated wastewater is discharged to the nature, zinc can be precipitate out with water as zinc hydroxide due to its low solubility product constant. Providing the value of solubility product constant of zinc (II) hydroxide as 3.0x10-16 (a) Write a chemical equation to represent the dissolution of zinc (II) hydroxide (2 point) (b) Determine...

the first displacement, B the second, and C the third. We can estimate from the diagram that the vector sum R is about 10 m, 40° west of north. The angles of the vectors, measured counterclockwise from the +x axis, are 58, 216, and 270°. We have to find the components of each.
