You have successfully purified a protein to homogeneity. From gel permeation chromatography studies, you determine that the protein has a molecular weight for 235,000 daltons.
write a electrn configuration for an octahedral complex, write the electron configuration for [RhCl6]^-3 in terms of MO labels for ground electronic state.
Draw the monobromination product that would be obtained from the radical bromination of methylcyclohexane? which product would obtained in greatest yield?
A 2.89 g sample of solid calcium carbide (CaC2) reacted with water to produce acetylene gas (C2H2) and aqueous calcium hydroxide.
Hydrazine, N2H4, is used as a rocket fuel. In the reaction below, if 80.1 g of N2H4 and 92.0 g of N2O4 are allowed to react, which is the limiting reactant?
Write the unbalanced equation for the formation of ozone gas from oxygen gas. (Include states-of-matter under SATP conditions in your answer.)
Calculate concentrations of OH- and the pH of each basic solution. Since NaOH donates on OH- ion for each NaOH molecule, the OH- concentration is equivalent to the NaOH molarity. The pOH is calculated as -log[OH-] and the pH is calculated as 14-pO..
Volume increases isothermally? Two pure gas species are mixed at constant temperature? Temperature increases isobarically? Pressure increases isothermally?
Consider 1 mole each of gaseous He and N2 at the same temperature and pressure. The diameter of N2 is 1.7 times that of He. State which gas (if any) has the greater value for: a) ; b) crms; c) average translational energy ; d) Z1; e) Z11; f) de..
