The UV light responsible for tanning skin has an average wavelength of 360 nm. Calculate the total energy (in kJ) absorbed by a person exposed to this radiation for 2.0 hours, given that there are 2.0 x 10^16 photons hitting earth's surface per square centimeter per second and the exposed body area is 0.38 m^2. You can assume that half of the energy is absorbed by the body and the other half is reflected.
What are the concentrations of H2SO4 and H2SO3 in a 25ml solution titrated with .1M NaOH. The first endpoint is reached after 37.89ml of NaOH are added (pH=7) and the second endpoint is reached after 43.57ml of NaOH are added (pH=9.8).
Following the equation for the combustion of 2C3H6O+8O2----->6CO2+6H2O+853.6 kcal. How much heat will be given off if 0.48 mol of acetone is burned completely?
What is the ground state electron configuration for the boron atom? What term symbols can arise from this electron configuration?
Starting Materials: Sebacoyl chloride, 1,6-Hexanediamine, Methyl chloroform, Sodium Carbonate monohydrate, Why is it necessary to have two immiscible solvents to make the nylon string?
What is the emprical formulae of the compound whose composition by mass is 1.32g of carbon dioxide contain 0.36g of carbon.
What is the enthalpy change (in kJ) for burning 73.0 g of methyl alcohol? 2)A reaction that is used to propel rockets is N2O4(l) + 2N2H4(l) --> 3N2(g) + 4H2O(g)
The empirical formula of a solid is AB2 and it dissolves to form the cation A2+ and the monoanion B-.Solid AB2 is added to water and allowed to reach equilibrium.
Alkenes can be converted to alcohols by reaction with mercuric acetate to form a ?-hydroxyalkylmercury(II) acetate compound, a reaction called oxymercuration. Subsequent reduction with NaBH4 reduces
the pressure of a sample of helium in a 1.00-liter container is .988 atm. What is the new pressure if the sample is placed in a 2.00 L container?
If one were to perform carbon dating on living clams instead of getting a zero age ( they are in fact living) one would get an age of approximately 400 years old for these living clams.
Estimate the equilibrium constant for the weak base C6H5CH2NH2, if a 4.53×10-1 M aqueous solution of C6H5CH2NH2 has a pOH 4.84 (make an exact calculation assuming that initial concentration
Determine the heat of formation of sulfuric acid, H2SO4 (l) from the following thermochemical equations: S8(s) + 8 O2(g)-->8SO2(g) H= -2374.6 kJ S8(s) + 12O2(g)-->8SO3(g) H=-3165.8 kJ H2O(l)+SO3(g)-->H2SO4(l) H=-132.3 kJ 2H2(g)+O2(g)-->2H2O(l) H=..
