A 7.00% solution by mass of an enzyme in water has an osmotic pressure of 20.0 torr at 291 K. Calculate the molar mass of this enzyme. (Assume that the density of the solution is 1.00 g/mL.)
A disulfide bridge forms between two cysteine residues. d. Disulfide bridges can exist between two amino acid residues on the same chain. e. Disulfide bridges are formed by an irreversible oxidation reaction.
Describe the bonding in N3- (Azide ion) in terms of an molecular orbital picture in which each terminal N atom is sp hybridized with one hybrid orbital accommodating one lone pair of electrons
Zinc metal reacts with yellow crystals of sulfur in a fiery reaction to produce a white powder of zinc sulfide. A chemist determines that 65.4 g of zinc reacts with 32.1 g of sulfur. How many grams of zinc sulfide could be produced from 12.0 g of ..
If 86.0 mL of .150 M HCL is needed to neutralize all the NH3 from a 2.25-g sample of organic material, calculate the mass percentage of nitrogen in the sample.
Nitration of chlorobenzene (C6H5Cl) occurs- faster than nitration of benzene and gives a mixture containing mostly o-and p-chlorobenzene
Nitric acid can be produced by the reaction of gaseous nitrogen dioxide with water. 3 NO2(g) + H2O(l) -→ 2 HNO3(l) + NO(g) If 927 L of NO2 gas react with water, what volume of NO gas will be produced? Assume the gases are measured under the same c..
