the radius of a helium atom is 32pm and its mass is 6.55 x 10-24g. what is the density of the atom in grams per cubic
Question- Why doesn't CpCr(CO)3H insert into simple olefins, such as but-1-ene, whereas Cp2ZrHCl does easily? The chromium complex is 18 electron, whereas the zirconium complex is 16 electron. And the Zirconium is d0, and I believe the chromium is..
Explain why is the concentration of solidCdC2O4 considered a constant. Explain why is the saturated solution ofCdC2O4 heated to 55- 60 degrees Celsius before titration with the KMnO4 solution
If you had a high-energy xenon particle beam and wanted to make gold, what element would you bombard
A piece of lithium metal was added to a flask of water on a day when the atmospheric pressure was 757.5 Torr. The lithium reacted completely with the water to produce 250.0 mL of hydrogen gas, collected over the water at 23°C, at which temperature..

If you add 12.1 g of tris base to a solution,then add enough HCl to the solution so that the pH is 7.9.How much HCl did you add to bring this pH?
Consider a bonding electron in a diatomic molecule from the molecular orbital point of view. If the probabilities of finding the electron in atomic orbitals Wa and Wb are 0.25 and 0.75, respectively, what is the LCAOwavefunction for the electron (..
One constitutional isomer of C2H4O2 has a pka of 40 while another has a pka of 5. Show lewis structures for each isomer and assign correct pka while succinctly explaining why the disparity in pka values.
A low-melting solid A was isolated, which combustion analysis showed had composition C9H10O. The substance gave a precipitate when treated with 2,4-dinitrophenylhydrazine solution.
Explain triose phosphate isomerase catalyzes the conversion of dihydroxyacetone -P to glyceraldehyde-3-P. The standard free energy change, D G°', for this reaction is +7.6 kJ/mol. Thus the observed free energy change (D G) for the reaction in eryt..
