The reaction for the decomposition of dinitrogen monoxide gas to form an oxygen radical is: N2O--->N2 + O2. If the activation energy is 250 kj/mol and the frequency factor is 8.0 x 10^11 s^-1, what is the rate constant for the first order reaction at 1000K
calculate the molarity of acetic acid in a vinegar sample knowing that 5.00 mL of vinegar requires 43.50mL of 0.105M NaoH to just reach the phenolphtalein endpoint in a tritration
At room temperature (20), milk turns sour in about 65 hours. In a refrigerator at 3, milk can be stored three times as long before it sours. What is the activation energy of the reaction that causes the souring of milk?
Consider the molecules CsO2, Na2O, K2O2, MgO, and H2O2 and answer the questions below. If there is more than one answer, give both separated by a comma with no spaces. Order doesn't matter.
A beaker with 130 mL of an acetic acid buffer with a pH of 5.00 is sitting on a benchtop. The total molarity of acid and conjugate base in this buffer is 0.100 M.
How many liters of flouridated drinking water would a 70 kg person have to consume in one day to reach this toxic level? How many kg of sodium flouride would be needed to treat a 7.49x 10^6 -gal reservior?
Write out the Michaelis-Menten model for an enzyme catalyzed reaction. State at least two assumptions that must be made for enzymes that follow the Michaelis-Menten model.
Although Pd (II) complexes with monodentate O-donor ligands are not as plentiful as those with P- , S- and As-donor Ligands
A reaction mechanism involving three steps is shown below. Identify all of the catalysts in the following mechanism.
If 290. mL of 0.130 M KOH are mixed with 200. mL of 0.430 M KOH, what is the molarity of the final solution?
Explain the significance of the chromic acid test. What would you observe in the case of a positive result? Do you expect 9-fluorenol to give a positive or negative result? What about the 9-fluorenone?
Methyl orange is an indicator that changes color over a range from pH =3.1 to pH =4.4 . What is Ka of methyl orange
We are asked to construct an energy level diagram (molecular orbital) for the molecule SO. We are then asked to comment on the ionic species of SO - bond order, bond distance etc. So far so good.
