Starting with 1.20 mL of an alcohol (MW 88, d = 0.8114 g/mL) and 3 mL of glacial acetic acid (MW 60, d=1.06 g/mL), calculate the theoretical yield in moles. (3 digits after decimal point)
At a certain temperature, the solubility of cadmium fluoride, CdF2, is 0.162 mol/L. Calculate its solubility product constant for this temperature.
Calculate the pH of a solution prepared by mixing 20.0 mL of 0.01 M HCl with 100.0 mL of 0.10 M HCN. For HCN, Ka = 1.0 x 10- 10. Assume that the volumes are additive.
which is known to change the activation energy of the process by 1.5 kJ. What will the rate of the reaction be with the catalyst when [A] = 0.0757 M at 315 K? Assume that the Arrhenius factor for this reaction has been determined to be 0.673 s-1.
State the selection rule for infrared-active molecules. Also, give an example of a molecule that is IR-active and identify an IR-active bond in the molecule, as well as where one would find its transition what frequency
considering the energetics of change of H and change of S values of solute/solvent interation, solvent/solbent interactions and aolut/solvent interactions
Household vinegar is 5.0% acetic acid (CH3COOH). IF you have 240.0 mL of vinegar, how many molecules of CH3COOH would there be?
Each of the measurements below describes length. Rank them from longest length to shortest length. 1x10^4cm, 1mile, 50in, 10m
the thermite reaction is performed using 8.6g Fe2O3 and 1.8g powdered Al metal. which reactant is in excess and by how much?
A 494 mL sample of hydrogen gas was collected over water at 25°C and a pressure of 753 torr. If the pressure of water vapor is 24.0 torr at 25.0°C, what mass of hydrogen gas (g) was collected? Do not enter units with your answer.
When 1 mol of HF is added to 1kg of water, the freezing point decreases by 1.9 C, but when 1 mol of HBr is added, the freezing point decreases by 3.7 C. Which is more highly separated into ions, HF or HBr
400 M formic acid (HCOOH) solution freezes at -0.758 degrees C. Calculate the Ka of the acid at that temperature. (hint: assume that molarity is equal to molality. Carry out your calculations to three sig figs and round off to two for Ka).
If 10.00 mL of 0.050M KI solution is mixed with 40.00 mL of other reagents what would be diluted concentration of KI
