Why is the structure of FMN and Coenzyme Q important for the function of the electron transport chain
The air in a laboratory was measured with a barometer to be 7.40 x 10^2 mm Hg. What is the laboratory air pressure in atm?
As we discussed in class, we are not necessarily limited to using a minimal basis set. We may write the molecular orbitals as a linear combination of as many atomic orbitals as we wish.
use maxwell distribution of speeds to estimate the fraction of CO2 molecules at 300K that have speeds in the range 200 to 250 m/s.
Mechanism for bromobenzene + magnesium turnings + annhydrous diethyl ether + benzaldehyde + H2SO4
A feed containing 15% by weight of solids is to be concentrated to 40 % solids using a double effect backward feed evaporator. The first effect is heated by steam at 413 K.
