The principle buffer system in human blood involves the weak acid, carbonic acid (H2CO3), and its conjugate base, bicarbonate ion (HCO3-),H2CO3(aq) + H2O(l) » H3O+(aq) + HCO3-(aq)
An equilibrium between carbonic acid, carbon dioxide and water is also established,
H2CO3(aq) » CO2(g) + H2O(l)
Humans unaccustomed to high altitudes tend to breathe much more rapidly (at least initially) because the partial pressure of O2(g) in air is much lower compared with that at low altitudes. Will rapid breathing at high altitudes tend to produce: (1) blood acidosis (blood pH lower than normal) or (2) blood alkalosis (blood pH higher than normal)? Explain your reasoning.
We are asked to construct an energy level diagram (molecular orbital) for the molecule SO. We are then asked to comment on the ionic species of SO - bond order, bond distance etc. So far so good.
Explain why it is important to use crucible tongs when you transfer the heated crucible
Caculate the wavelength of light( in nanometers) that is absorbed when the electron in a He+ ion goes from the n=2

Celsius is allowed to expand into an evacuated vessel of 2.50 L volume. Does the gas do work? Explain
What is the Volume of 0.75 mol of Benzene (C6H6) at 20.7 degrees C. The density of Benzene is 0.879 g/mL
Briefly comment on whether or not this experiment shows that you can successfully model the packing of atoms in a liquid by randomly packing
The density of acetic acid vapor at the normal boiling point, 118.5 degrees C, is given by 3.15 g/L (normal boiling point is the boiling temperature at P = 1 atm). a) calculate the fraction of the vapor that is monomer and the fraction that is dime..
