consider the results of an experiment in which nitrogen dioxide reacts with ozone at 2 different temperatures, 13 degrees Celsius and 29 degrees Celsius. If the activation energy is 29 kI/mol, but what factor does the rate constant increase with this temperature change?
laser beam to read the digital video data off a DVD disk. What is the frequency of this red colored visible light?
What is the pH of a solution resulting from the titration of 50 mL of 0.050 M acetic acid solution, CH3COOH, with 50 mL of 0.050 M NaOH solution
Then you precipitate the calcium ion in solution by adding sodium oxalate Na2C2O4. The precipitate is calcium oxalate, CaC2O4. You find that a sample of limestone weighing 128.3 mg gives 140.2 mg of CaC2O4. What is the mass % of calcium in the lim..
A 4.305-gram sample of a nonelectrolyte is dissolved in 105 grams of water. The solution freezes at -1.23°C. Calculate the molecular weight of the solute. Kf for water = 1.86°C/m.
A solution is prepared by dissolving 5.32 grams of potassium nitrite (a food preservative, as Clark Griswold would explain) into about100 ml of DI water in a volumetric flask. Enough water is then added to give a total volume of 250.0 ml. What are..
Calculate the amount of energy in the form of heat that is produced when a volume of 4.70 L of SO2 (g) is converted to 4.70 L of SO3 (g) according to this process at a constant pressure and a temperature of 1.00 bar and 25 degree celsius.
along with chemical shift arguments and resonance theory, assign all of the peaks in the 1H and 13C NMR spectra of 4-propoxybenzaldehyde. Briefly explain you reasoning.
Choose the answer which lists the atoms Pb, Sb, Ge, and Al in order of increasing atomic radius (smallest atom listed first).
For 1-Chloropropane, draw 3 eclipsed, 2 gauche, and 1 anti conformations. Assume a chloro is the same size as a methyl group.
Draw a flow chart that illustrates how you would purify an organic compound that is contaminated with inorganic solids that are water soluble
Assume that the density of the mixed solutions is 1.00 g/mL, that the specific heat of the mixed solutions is 4.18 J/(g celcius), and that no heat is lost to the surroundings. The deltaHrxn for the neutralization of NaOH with H2SO4 is -114 kJ/mol ..
the calculation of the Ksp value be affected if the endpoint of titration was surpassed (i.e. too much HCl was added)?
