two naturally occurring isotopes with atomic weights 184.9530 and 186.9560. What is the percent abundance of the lighter isotope
Let us assume that we are working with a vesicle created from a biological membrane and wish to determine whether the various proteins are integral or peripheral and exposed to which side of the membrane
Calculate the % yield of Al2(SO4) from the reaction: 2Al(OH)3(s) + 3H2SO4(aq) -> Al2(SO4)3(s) + 6H2O(l) given that 205 g of Al(OH)3 react with 751 g of H2SO4 to yield 252 g Al2(SO4)3.
A student measures the conductivity of an Fe2(SO4)3 solution and determines it to be a strong electrolyte. The student incorrectly lists the species in solution as O-2, S-2, Fe+3. Give the correct list of species in the solution.
Initially a mixture contains 0.795 mol each of N2 and O2 in an 8.00 L vessel. Find the equilibrium composition of the mixture at 3900 degrees Celcius.
Draw the following protein molecule, Need to draw the following molecule (using the lewis condensed line structure).
The pKb values for the dibasic base B are pKb1 = 2.1 and pKb2 = 7.8. Calculate the pH at each of the following points in the titration of 50.0 mL of a 0.75 M B(aq) with 0.75 M HCl(aq).
Blood alcohol content (BAC) is often reported in weight-volume percent (w/v%). For example, a BAC of 0.08% corresponds to 0.08 g CH3CH2OH per 100 mL of blood. In Ontario, and the rest of Canada, the maximum legal BAC for fully licensed drivers is ..
