What is the pH change when adding 0.15 moles of HCl to a 1 L buffer containing 1.0 M acetic acid and 1 M sodium acetate?
assume two 200.0-l tanks are to be filled separately with gases helium and hydrogen. find mass of each gas is required
In the following conditions calculate the moles of hydrogen and the pressure in each flask where the volume is negligible. Each flask is originally 275K with .455 mols of hydrogen gas and .7atm of pressure. Then one flask is heated to 500K while t..
Determine the equilibrium constant for the following reaction at 298 K. SO3(g) + H2O(g) ? H2SO4(l) ?G° = -90.5 kJ
What is the exact alkalinity of a water that contains 0.6580 mg/L of bicarbonate, as the ion, at a pH of 5.66? No carbonate is present.
Titration of 664 mg of a pure organic carboxylic acid, H2A, showed a rapid change in pH at 40.00 mL and at 80.00 mL of 0.100 M NaOH titrant. When 40.00 mL of NaOH was added, the pH was 5.85, and at 60.00 mL of NaOH the pH was 8.08. What is the mol..
Calculate the standard enthalpy of the reaction, Delta(H) rxn}, for the thermite reaction: 2Al(s) + Fe2O3(s) ----> 2Fe(s) + Al2O3(s) Elements in their standard state have an enthalpy of formation value of zero

Derive the rate law expression for the chlorination of vinyl chloride based on this mechanism.
A biochemist is thrilled with her discovery of a new enzyme. In order to characterize this new enzyme, she uses osmotic pressure. A solution containing 0.190 g. of this enzyme in 187. mL of solution has an osmotic pressure at 298 K. of 1.18 torr.
An insulated tank is divided into two equal parts. Both halves contain the same ideal gas but one is at 300K and 2 bar while the other one is at 1 bar.
You are given solutions of HCl and NaOH and must determine their concentrations. You use 26.6 mL of NaOH to titrate 100. mL of HCl and 21.4 mL of NaOH to titrate 50.0 mL of 0.0796 M H2SO4. Find the unknown concentrations. NaOH
