The complexes [Mn(H2O)6]2+, [Fe(H2O)6]3+, [MnCl4]2-, and [FeCl4]- all have magnetic moments of nearly 5.92 BM. What does this tell you about the geometric and electronic structures of these complexes? Why is the spin-only formula so precise in these cases?
predict the products from the reaction of the following compounds with excess h2cro4 in the presence of sulfuric acida.
Hydrochloric acid B) Ammonium Hydroxide 2) Identify the geometry of the iron(III) complex in water and the complex ions produced in the above reactions
An electron in the n2= 5 level of an H atom emits a photon of wavelength 1282.17 nm. To what energy does the electron move. Is the photon in the visible region.
Consider the reaction HgS + O2 → SO2 + Hg. If 200.0 grams of HgS reacted with 150.0 grams of O2, what is the limiting reagent.
An aqueous solution containing 15.6 g of an unknown molecular (nonelectrolyte) compound in 109.5g of water was found to have a freezing point of -1.9 degrees C.
A sample of a gas weighs 2.006 g and has a volume of 1060.0 mL at 795.0 torr and 32.0 degrees Celsius. What is its molar mass?
slower than Friedel-Crafts alkylation of benzene and gives a mixture containing mostly o- and p-tert-butyltoluene. d. slower than Friedel-Crafts alkylation of benzene and gives mostly m-tert-butyltoluene.
Calculate a final molarity (M) for a solution if 10. mL of Part "d" is diluted to 0.20 L with pure water. 11 g. Discuss the miscibility of ethylene glycol in water using London dispersion, dipole-dipole, hydrogen bond interactions
What is the final pressure in atm of a 3.05 L system initially at 724 mm Hg and 298 K, that is compressed to a final volume of 2.51 L at 273 K?
use the bond dissociation energies of h2 435 kjmol and of y typical carbon-carbon bond 347 kjmol to decide which bond
Choose the stronger of each pair of acids, respectively, and explain why: a) HBrO3 or HBrO b) HBrO2 or HIO2 A. a) HBrO because Br has a lower oxidation state (fewer number of O atoms around it) in HBrO than in HBrO3
