Graph the relative energy vs. torsion angle around the indicated bond like we did for ethane and butane in class. Depict the molecular Newman Projection for each local minimum and maximum. Of Ethylbenzene
Determine the compounds Cl2, HCl, F2, NaF and HF which compound has a boiling point closest to that of argon. Define
The radius of a potassium atom is 235 pm. Determine the density of potassium in g/cm3.
The vapor pressure of pure ethyl bromide at this temperature is 400.0 torr. Assuming an ideal solution, what is the molecular mass of the compound?
Given Radon has a density of 9.73 g/L, How many cubic Nanometers of radon would you need if you wanted 43.780g of radon?
What is the change in energy, Delta E, in kilojoules per mole of hydrogen atoms for an electron transition from n=8 to n=2? Express your answer in kilojoules per mole to three significant figures.
The only difference is the H+-ATP stoichiometry. Given that the pH on the outside of the xeno-mitochondrial membrane is 6.014,
Consider the following reaction: CO(g)+2H2(g)-->CH3OH(g) Kp=2.26x10^4 Calculate deltaGrxn for the reaction at 25 C at equilibrium and when: PCh3OH = 1.1 atm, PCO = PH2 = 1.3*10^-2 atm. I got the correct original deltaG, it's -24.8 KJ
Draw the amine from the following: A Hofmann degradation of a primary amine forms an alkene that gives butanal
HCl by mass and has a density of 1.20g/ml .How much concentrated solution would you take to prepare 2.75L of 0.430 M HCl by mixing with water?
What is the equivalent mass of metal that is dissolved in sulfuric acid during hydrogen release if 2.27 g metal reacts with 30 ml 33 w/w% H2SO4 (density 1.25 g/cm^3,
A sample of neon effuses from a container in 77 seconds. The same amount of an unknown noble gas requires 157 seconds. identify the gas.
Restricting yourself to straight-chain (unbranched) compounds, draw the structures of the possible constitutional isomers of pentene. There are two "variables" -- the position of the double bond; and cis/trans isomerization at that double bond.
