The 1995 Nobel Prize in Chemistry was shared by Paul Crutzen, F. Sherwood Rowland, and Mario Molina for their work concerning the formation and decomposition of ozone in the stratosphere. Rowland and Molina hypothesized that chlorofluorocarbons (CFCs) in the stratosphere break down upon exposure to UV radiation, producing chlorine atoms. Chlorine was previously identified as a catalyst in the breakdown of ozone into oxygen gas. Using the enthalpy of reaction for two reactions with ozone, determine the enthalpy of reaction for the reaction of chlorine with ozone. 1. ClO + O3 -> Cl + 2O2 DeltaH of rxn = -122.8 kJ 2. 2O3 -> 3O2 DeltaH of rxn= -285.3 kJ 3. O3 + Cl -> ClO + O2 DeltaH of rxn = ?
The isothermal compressibility of graphite is 1.56 × 10-7 bar-1. At what pressure is density equal to density of diamond?
If 0.00936 mol neon gas at a particular temperature and pressure occupies a volume of 210. mL, what volume would 0.00793 mol neon occupy under the same conditions? What mass of neon gas is required to fill a 4.44-L container to a pressure of 1.30 a..
How is it possible that hard water can also be very saline ie The River Murray in South Australia? If sodium is added to soften hard water, then wouldn't the presence of salt in hard water 'soften' the water naturally
what is the frequency of the photons emitted by hydrogen atoms when they undergo transistions from n=5 to n=3
A 0.021 mol sample of a weak acid, HX, is dissolved in 575 mL of water and titrated with 0.41 M NaOH. After 29 mL of the NaOH solution has been added, the overall pH = 6.074. Calculate the Ka value for HX.
Assuming that no heat is lost to the cup or the surroundings, what will the final temperature of the water be? The specific heat capacity of iron = 0.449 J/g°C and water = 4.18 J/g°C.
Determine the number of moles of oxygen that would be needed to completely combust 0.0350 moles of benzene
Determine how much Ammonia would be formed if 187 grams of calcium carbonate CaCO 3 are formed?
A solution is made by dissolving 0.679 mol of nonelectrolyte solute in 871 g of benzene. Calculate the freezing point and boiling point of the solution.
An unknown amount of magnesium metal reacts with 100.0 mL 0f 0.100M aqueous hydrochloric acid. The final solution is acidic, and titrated to an endpoint using 0.150 M aqueous sodium hydroxide. The endpoint was neutralized after the addition of 16...
Describe why this is based on the wavelength range that is transmitted. What color would you see if you mixed the two solutions with ?max = 520 and ?max = 610?
A molecule can be polar or nonpolar depending upon the nature of the bonds and the shape of the molecule. For a molecule that has different outer atoms the molecular symmetry will decide the polarity.
