For the reaction 2NO + Cl2 = 2NOCl, if the change in Molarity is CL2 is 2.41 x 10 -2 M in one second, How do you find the rate of formation of NOCl
Describe how you would prepare 150.0 mL of a pH = 5.00 buffer solution from a solution of 0.200-M aniline, C6H5NH2, a weak base
In the laboratory a student finds that it takes 96.8 Joules to increase the temperature of 14.3 grams of solid diamond from 24.0 to 38.1 degrees Celsius.
Compute the expected pH when 0.5mL of 0.1 M HCL is added to 30.0mL pure water. Do the same computation when the same amount of HCL is added to 30.0mL of your original .05M buffer. Compare the compute pH to the actual measured pH.
