The blood buffer system is made up of H2CO3 and HCO3. Describe with the use of equations how this system responds to added H3O and to added OH.
For drug development, it is crucial to optimize the half-life of elimination of the drug so that the drug has long enough to act but not enough time to cause harmful side-effect.
a 12.6 g sample of NH4NO3 is dropped into a constant-pressure calorimeter containing 175 g of water at 23.5 C. What temperature will the water reach, assuming that the calorimeter container does not gain or lose any heat?
If 2.50 g CuSO4 are dissolved in 8.0 x 102 mL of 0.25 M NH3, what are the concentrations of Cu2+, Cu(NH3)42+, and NH3 at equilibrium
When 190.0 mL of 0.360 mol are added to 190.0 mL of 1.00×10?2 M AgNO3 (aq), what percentage of the Ag+ is left unprecipitated?
Determine deltaHvap for a compound that has a measured vapor pressure of 24.3 torr at 273 K and 135 torr at 325 K.
What is the single-particle collisional frequency (for diatomic Nitrogen)at sea level, with 341 and 1.0 atm. The corresponding single-particle collisional frequency is reported as 10^10 s^-1.
"Air" bags for automobiles are inflated during a collision by the explosion of sodium azide, NaN3. The equation for the decomposition is 2NaN3(s) ? 2Na(s) + 3N2(g). What mass of sodium azide would be needed to inflate a 9.8-L bag to a pressure of 2...
