The intermolecular distance of CO is 113.1 pm. the molecular mass of 12C is exactly 12 g/mol. Explain the molecular mass of 16O is 15.995 g/mole. Find out the value of the rotational energy of 12C16O molecule described by J=0 and by J=1.
if 40.0 kJ of energy is absorbed by 500.0 g of water at 10.0 degrees celcius what is the final temperature of water?
In metallic magnesium explain what fraction of the 'molecular orbits' contained in the valence band plus the conduction band is occupied by electrons? Explain
you mix 242 grams of NaCl with enough water to form 500 mL of solution. What is the final molarity?
The half-life for the reaction at 550C is 81.3 seconds. How long does it take for 89% of phosphine sample to decompose?
A closed container is filled with oxygen. The pressure in the container is 375kPa . What is the pressure in millimeters of mercury
What are the resonance structures and intermediates in the formation of bromoacetanilide from the reaction of acetanilide and bromine liquid with acetic acid

A chemist dissolves 0.9 g of an unknown monoprotic (one acidic H) acid in water. She finds that 14.6 mL of 0.426 M NaOH are required to neutralize the acid.
A mixture of gases contains 1.75 g of N2, 4.84 g of H2, and 3.48 g of NH3. If the total pressure of the mixture is 5.73 atm, what is the partial pressure of each component
An equilibrium mixture contains .870 mol I2, and .290 mol H2 in a 1.00 L flask. I found the equilibruim constant to be .172 which is correct.
After filtration, the remaining NaCO3 solution needed 0.004moles of H Cl for neutralization. Calculate the number of moles of NaCO3 remaining after filtration., therefore deduce the number of moles of BaCl2 which reacted with the NaCO3 solution.
The Henry's Law constant for CH3Br gas in water at 25 oC is 0.159 mol/L-atm. Calculate the solubility of CH3Br in water at 25 oC in moles/L if the partial pressure of CH3Br in the headspace above a water sample is 1.71 atm.
