The M+ values for ?-chloroacetyl chloride, ?-chloro-2,6-dimethylacetanilide, and lidocaine are 112, 197, and 234 m/z, respectively. For each of these three chemicals, state how the "parity rule" is (or is not) obeyed by the MS data. If this question cannot be answered for a chemical, state briefly why not (for example, what additional data would be needed or why the situation is ambiguous).
Ethylene glycol (EG) is a commonly used automotive antifreeze. Calculate the boiling point and the freezing point of the 25% EG solution if Kb=0.512oC/m and Kf=1.86oC/m for water. Molar mass of EG=60.05 g/mol.
Two scientists are experimenting with pure samples of isotope X, a highly radioactive substance. The first scientist has a sample with a mass of 20 grams.
Study of a first-order reaction, In the study of a first-order reaction, A--->B, it is found that A/Ao=0.125 after one hour. The system initially consisted of 0.20 mole of a gaseous A at 25 degrees C and 1 atm
Suppose that you are climbing a high mountain and the oxygen partial pressure in the air is reduced to 75 torr. Estimate the percentage of the oxygen carrying capacity that will be utilized,
If a solution is made by mixing 20.0 mL 0.3 M NaCH3COO with 30 mL 0.4 M CH3COOH, calculate the pH of the solution? For acetic acid, K = 1.76 x 10-5.

what is the minimum rate that fresh air has to be supplied to the room so that the concentration of CO2 in the room doesn't exceed 0.500% by mole? Assume the room is well mixed, and the volume of the solid dry ice does not change.
Write the reactions for the preparation of the diaonuim salt for the coupling of the salt with the sodium salt of 2-napthol.
What is the volume of Ammonia gas is dissolved in 40.0 mL of 15.0 M NH 3 solution at STP and Determine what is the vapor pressure of a solution made by dissolving 65.4grams ammonia in 259 grams of H 2 O at 55.0 ºC?
Draw any one of the skeletal structure of a secondary alkyl bromide with a molecular formula C6H13Br and two stereogenic centers.
There are conventions for naming and constructing the formulas for acids and bases just as there are for other types of compounds. There are 3 main rules for naming acids.
The compound, an eight-carbon alkane, serves as the 100 octane standard for gasoline. It has five methyl groups, one quaternary carbon, tests negative for C-C double bonds and gives four monochloro substitution products
