Consider a 100 mL aqueous standard solution containing 100 μg/L of iodomethane that is stored in a well sealed 1 L flask (i. e., 900. mL of air). The following data is provided for iodomethane;

Po = 53,700 Pa, Cw Sat = 0.0977 mol L-1, KH = 542 Pa m3 mol-1

a) Calculate the concentration of iodomethanein the water and headspace of the bottleat equilibrium at 25°C.

b) If the bottle is opened after equilibration and all of the air in the headspace is flushed out and replaced by fresh air, what will the concentration of iodomethane be in the aqueous solution after the equilibrium is re-established?

c) Calculate the fraction of iodomethane present in the liquid water of a cloud aerosol characterized by VH2O(l)= 0.10 mL per 100. L air. How will your answer change if the temperature is 5°C?

If 34.2 grams of lithium react with excess water, how many liters of hydrogen gas can be produced at 299 kelvin and 1.21 atmospheres? 2 li (s) + 2 h2o (l) yields 2 lioh (aq) + h2 (g)

The formation of a solid, also known as a is an indication of a chemical change. precipitate particulate particle powder

Many reactions take place in aqueous solution. when potential reactants are mixed, a reaction will occur if there is some driving force that favors the formation of products. it is often convenient to categorize reactions in terms of these driving forces: precipitate formation, in which an insoluble solid is formed, weak electrolyte formation, as in a neutralization reaction involving water, or transfer of electrons, as in a redox reaction. these reactions can be represented by full molecular equations, which contain all species in the reaction mixture, or by net ionic equations, which show only the species that actually undergo a change. the latter does not contain the spectator ions, which do not undergo a net change or do not take part in the reaction. part a when the following two solutions are mixed: k2co3(aq)+fe(no3)3(aq) the mixture contains the ions listed below. sort these species into spectator ions and ions that react. drag the appropriate items to their respective bins. view available hint(s) spectator ions ions that react part b what is the correct net ionic equation, including all coefficients, charges, and phases, for the following set of reactants? assume that the contribution of protons from h2so4 is near 100 %.ba(oh)2(aq)+h2so4(aq)→ express your answer as a chemical equation. view available hint(s) nothing provide feedback
