The ozone layer is about 20 km thick, has an average total pressureof 10 mm Hg(1.3 * 10^-2 atm ) , and has an average temperature of 230 K. The partial pressure of ozone in the layer is only about 1.2 * 10^-6 mm Hg( 1.6 * 10^-9 atm ).
How many meters thick would the layer be if all the ozone contained in it were compressed into a thin layer of pure O3 at STP?
I know you have to use the PV= nRT formula and Dalton's partial pressure, but i dont know to to integrated Daltons Partial pressure law into this question.
Knowing that the arenium ion intermediate has positive charge on the ortho and para carbons, draw each resonance structure - one which shows the positive charge on the ortho carbon and one which shows the positive charge on the para carbon. You wi..

0.5865 g sample of lactic acid (HC3H5O3) is burned in a calorimeter whose heat capacity is 4.812 kJ/ oC. The temperature increases from 23.10oC to 24.95oC.Calculate the heat of combustion of lactic acid a. per gram b. per mole.
NaOH + CO2 -> Na2CO3 + H2O. If the average human body discharges 745 g of CO2 per day, how much NaOH is needed each day for each person in the spacecraft.
how many moles of AlCl3 is that b.) How many moles of NaOH is that c.) Which is your limiting reagent d.) How much (in grams) solid Al(OH)3 is formed e.) What is the concentration of NaCl in the Erlenmeyer flask (total volume = 50.00 mL)
Cyclohexane can be used as a solvent for freezing point depression measurements. When 1.07 g of naphthalene (MW = 128.17 g/mol) is mixed with 51.29 g of cyclohexane, the freezing point of the resulting solution is 3.29 °C.
What effect does adding an enzyme to a reaction have on this? On delta G? What are the roles of delta G in biochemical reactions (list two)?
What was the concentration of the original hydroxylamine solution? What is the pH at the equivalence point? Which indicators should be used to detect the endpoint of the titration?
Complete the following table by calculating the missing entries. In each case indicate whether the solution is acidic or basic. pH pOH [H+] [OH -] acidic or basic
In an experiment, at this temperature, 1.10 mol of H2 and 1.10 mol of F2 are introduced into a 1.08-L flask and allowed to react. At equilibrium, all species remain in the gas phase.
The structure of olivine [M2SiO4(whare M=Mg,Fe)] can be viewed as a ccp arrangment of oxide ions with Si(IV) in tetrahedral goles and the metal ions in octahedral holes
Recall "living" carbon samples show 15.3 d/min*g (carbon). note: CaCO3 is 12.00% carbon, and 14C has a half-life of 5730yr.
