What polypeptide would be synthesized from the following template strand of DNA:3' CGG AGA CGG ACG 5'
The natural abundance of 13C is only 1.1%. Furthermore, its sensitivity in NMR spectroscopy (a measure of the energy difference between a spin aligned with or against an external magnetic field)
Suppose heat is lost or absorbed by the calorimeter itself would it give a higher or a lower value that the usual value or would this have remained unchanged
Problem- Formula H2O, mass in grams 7.6, molar mass 18g/mol, moles .42 mol, 1) What are the mole and how many atoms in the element
In trans-1,2-dibenzoylethylene, even though the conjugated C=O group frequency coincides directly with the expected C=C stretching fequency, we would not have expected to observe the late stretching mode in the infrared spectum. Why
A student obtained the following data from this experiment. Calculate the molar mass of this unkown liquid.
Calculate E when 770.0 g of CH3OH(g) completely reacts at a constant temperature of 300 K and constant pressure of 0.95 atm. R = 8.314 J/mol*K and R = 0.08206 atm*L/mol*K.
Plutonium-239 is a byproduct of the fission reaction used to produce energy in nuclear power reactors. It has a half-life of 24,400 years. A student determines that it will take 97,600 years for the radioactivity of a Pu-239 sample to drop to one-..
