a. Carbon monoxide is a poisonous gas for the reason that if binds strongly to hemoglobin, preventing the transport of oxygen by blood. The bond in a 12C16O molecule has a force constant of k=1860 N/m. Compute the vibrational frequency (v) of the molecule as well as energy separation between two neighboring vibrational energy levels.
b. Forecast the vibrational frequency of 13CO16 given that the force constants of isotopes are the same.
c. Define why the force constant value isn't affected by isotopic substitution.
How many moles of iron(III) hydroxide are needed to react with excess nitric acid to produce 67.0 g iron(III) nitrate
Using the fact that on the surface of the Earth, where g is constant, 1 kg has a weight of 2.2 lbs, find your mass in kg. C) Convert your height in feet and inches into meters (1 ft = 30.48 cm; 1 in = 2.54 cm).
explain why rutherford expected all alpha particles to go through the gold foil undisturbed.
Use Kirchoff's law to calculate ?vapH , the molar enthalpy of vaporization, of a substance at 218.15 K, given that its standard enthalpy of vaporization is ?vapH=32.45 kJ mol at 25.0ºC.

A 47 kg sample of water absorbs 348 kJ of heat. If the water was initially at 28.7 C what is its final temperature.
Show how to produce 2-methoxy-1-butanol from the epoxidation of 1-butene. The reaction was carried out in methanol.
Compounds in a and b were named incorrectly. On a sheet of paper draw the molecule that fits the given description. From the structure you drew determine the correct IUPAC name. Write the correct IUPAC name in the blank.
the rate constant for the second order -reaction is NOBr(g)------>NO(g)+1/2Br2(g) is 48 L/mol*min at a certian temperture. How long will it take for 90.0% of a .0200M solution of NOBr to decompose
The two following compounds are called crown ethers and they are used to protect alkali metal ions in some reactions. The oxygen atoms in each are joined -(CH2)2- or -(CH2)3- groups.
53.5 g of an ideal gas of molecular weight = 10.5 g/mol is confined at a pressure of 50 kPa. The density of the gas is 0.164 g/L. Compute the temperature of the gas in degrees Celsius.
