Calculate pCu at the equivalence point in the titration of 20.0 mL of 0.0161 M CuSO4 with 0.0100 M EDTA at pH 8.00.
The below table lists pressure and volume measurements for air in a cylindrical piston of an air compressor. The variables may be assumed related by: PV^k=C
celcius have enough energy to overcome the activation energy barrier for a particular reaction, what is the activation energy for this reaction
Why E2 is favored over SN2, Sn2 requires a strong nucleophile while E2 requires a strong base. But relatively compared if you have a very strong base the E2 is preferred. Why is it so?
The mole fraction of benzene in the solution is 0.590. Assumeing ideal behavior, calculate the mole fraction of toluene in the vapor above the solution.
A 75.0-mL volume of 0.200 NH3 is titrated with 0.500 M HNO3 . Calculate the pH after the addition of 19.0 mL of HNO3
Calculate the pH of a buffer made from mixing 10.0 mL of 0.100M NaC2H3O2 and 10.0 mL of 0.100M Hc2H3O2. a) Calculate the pH of the buffer when 5.00 mL of a 0.0100M HaOH is added.
A chemist produces 460 mL of oxygen gas at - 43 °C and constant pressure. To what Celsius temperature must the oxygen be warmed in order for it to have a volume of 600 mL?
Dolomite is a mineral consisting of calcium carbonate (CaCO3) and magnesium carbonate (MgCO3). When dolomite is strongly heated, its carbonates decompose to their oxides (CaO and MgO) and carbon dioxide is expelled.
A 50 mL sample of 0.10 M HCl is mixed with 100 mL of 0.20M NH3. What is the resulting pH? (Kb for NH3 = 1.8 x 10-5).
