Explain which of the following gases would be expected to behave most nearly preferably under the same conditions? H2, F2, HF. Explain
A student has prepared a 0.309 M solution of Barium hydroxide and a 0.443M solution of hydrochloric acid for you. Determine the volume of the hydrochloric acid solution will be needed to exactly neutralize 10.0 mL of the Barium chloride solution.
A solution of the weak acid, HF, and a solution of the strong acid, HCl, have the same pH. Which solution will require the most sodium hydroxide, NaOH, to neutralize
To an open beaker containing 500ml of water at 298k, 20g of sodium metal is added. the reaction proceeds quite rigorously but ultimately comes to rest after consuming all of the sodium metal and thermally reequilibrating with the surroundings. The..

determine the empirical formula for each substance.1. a dead alkaline battery is found to contain a compund of mn and
What amount of the ultimate carbonaceous BOD is remaining after this time?
If the initial pressure of the ether is 135 torr, what is its partial pressure after 1420 s? (Note, since the volume and temperature don't change, the pressure is directly related to number of moles and so the pressure can be treated similar to co..
