When aqueous solutions of potassiumfluoride and nitric acid are mixed, an aqueous solution of potassiumnitrate and hydrofluoric acid results. Write the net ionic equation for the reaction.
Household ammonia, NH3 is a weak base. 10.00mL of ammonia was titrated with 0.1683 mol/L HCL 22.74 mL was required to reach the equivalence point. Calculated the PH after 0.00mL, 6.52mL, 11.37mL, 28.28mL, of hydrochloric acid solution are added.

An ammonia/ammonium buffer solution contains 0.19M NH3 and 0.61M NH4+. The Kb value of ammonia is 1.8 x 10^-5 . Calculate the pH of this buffer.
How much heat (in kJ) is released when 15.0 L of CO at 85 degrees C and 112 kPa reacts with 18.5 L of H2 at 75 degrees C and 744 torr?
Each mole of cyclohexene reacts with four moles of H2O2 to give adipic acid. You added about 3.6 grams of H2O2 to your reaction mixture (12 grams of a 30% solution were added). Calculate the mass of H2O2 required to react with 2.00g of cyclohexene..
Which of the available reagent(s), if any, will oxidize Fe(s) while leaving Cu(s) unreacted? If none of the available reagents can be used for this purpose, then identify another reagent from the table that could be used. For each reagent you've i..
