A buffer solution consists of a 1.00 L aqueous solution containing 0.0080 mol of benzoic acid, and 0.0080 mol of sodium benzoate.
Establish the pH region for this buffer solution at 25 °C.
(Note: K = 6.3 x 10- for CH=COOH(aq))

Americium-241 undergoes fission to produce three neutrons per fission event. if a neutron-absorbing material is mixed in with this sample so that the rate of neutron production drops down to 1.8 neutrons per fission event, which will be effective at achieving a critical mass? check all that apply. remove a deflective shield surrounding the sample. remove absorbent material mixed in with the sample. compress the sample of americium-241.

To find the enthalpy of a reaction in the lab, you measured the of the reactants and the change during the reaction.
