2NOCl(g) → 2NO(g) + Cl2(g)
At 450 K the rate constant is 15.4 atm-1s-1. How much time (in s) is needed for NOCl originally at a partial pressure of 46 torr to decay to 25.8 torr?
Li is in row 2 of the periodic table, Na is in row 3, and K is in row 4. How do their row numbers affect how their electron configurations end.
You are given solutions of HCl and NaOH and must determine their concentrations. You use 30.6 mL of NaOH to titrate 100. mL of HCl and 18.0 mL of NaOH to titrate 50.0 mL of 0.0796 M H2SO4. Find the unknown concentrations.

0.100 moles of NaOH are combined with 0.125 moles acetic acid. The mixture is taken to a final volume of 100.0 ml. What is the expected pH of the solution. Ka = 1.76 x 10^-5
What is the pH of Sodium Acetate solution before the HCL is added and after the HCL is added?
Methanol (CH3OH) reacts with oxygen to produce carbon dioxide and water. How many grams of oxygen will be required to react completely with 200 grams of CH3OH? What mass of water will be produced during the reaction?
Describe the error that has occured; that is , is the mass of the anhydrous salt remaining in the crucible reported as being too high or low? Explain.
What would be the expected CNMR, HNMR, and IR spectra for lidocaine, 2,6-dimethylaniline, and alpha-chloro-2,6-dimethylaniline?
What would happen to the A450 valure for a sample as test tube#10(is included 1ml of 0.0025M Fe(NO3)3 , 1ml of 0.0025M KSCN, and 5ml of 0.1M HNO3 ) ,if accidentally added 5 drops of disodium hydrogen phospate
For each of the following cases, identify the order with respect to the reactant, A. Case (A ----> product) 1. The half-life of A increases as the initial concentration of A decreases
