A 1.00 L buffer solution is 0.150 M in HC7H5O2 and 0.250 M in LiC7H5O2. Calculate the pH of the solution after the addition of 100.0 mL of 1.00 M HCl. The Ka for HC7H5O2 is 6.5 x 10-5.
Draw the electron-dot formula for each of the following molecules or ions: a) HCCH (ethyne); b) CS2 (C is the central atom); c) NO^+
Calculate the binding energy per nucleon (in MeV) for P-32 (atomic mass = 31.9739 u). mass H = 1.007825 u and mass n = 1.008665 u.
We want to change the volume of a fixed amount of gas from 725ml to 2.05L while holding the temperature constant. To what value must we change the pressure if the initial pressure is 110kpa
Consider an ideal gas which is allowed to expand slowly under constant temperature conditions. Derive an expression for the heat change for such a process, explaining any key stages in the derivation.
Determine what would you use to prepare 10 ml of 0.2M CaCl 2 from the 20M stock solution and find out which solution is with pH > 7, but is not an Arrhenius base in the strict sense?
You dilute it with 25mL of water and 10mL of H2SO4. You titrate the solution with 19.80 mL of KMnO4. The (MnO4)- is reduced to (Mn) 2+ by the unknown solution. a) What is the equivalent weight of (MnO4)- for the experiment
Based on the given chemical equation, how many grams of aluminum are needed to react with 0.6 moles of hydrochloric acid? Al + HCl yields AlCl3 + H2
A solution is initially 0.050M in acetate, CH3COO- (Kb = 5.6 x 10^-10). 10.0mL of 0.10 M HCl is added. Calculate Ka for the conjugate weak acid of CH3COO-
