Why 3 is not a valid value for the magnetic quantum number of an electron in 5d subshell? Please justification
In a particular photoelectron spectrum using 21.21 eV photons, electrons were ejected with kinetic energies of 11.01 eV, 8.23 eV, and 5.22 eV. Sketch the molecular orbital energy level diagram for the species, showing the ionization energies of th..
Calculate the solubility of KHTar in three solvent systems: pure water, 0.10 M KNO3, and 0.10 M NaNO3. The solubility of KHTar will be determined by titration of the HTar- with standard NaOH solution.
Calculate the wavelength of each of the following frequencies of electromagnetic radiation. 1105 kHz (typical frequency for AM radio broadcasting) (assume four significant figures)
In the laboratory you dissolve 13.2 g of sodium bromide in a volumetric flask and add water to a total volume of 125 mL.
A solution of H2SO4 was standardized against a sample of CaCO3 (FW = 100) weighing 0.7242g. The same required 29.90 mL of the acid and the excess acid was back titrated with 10.20mL of NaOH solution. If 1.00mL of the acid will react with 1.02 mL o..
If Sodium hydroxoide has a H+ of 4.2 x 10^ -10, then what is its OH- , pH, and pOH. If hydrochloric acid has a pOH of 11.5, then what is its pH, OH-, and H+. If potasssium hydroxoide has a pH of 2.5, then what is its H+, OH-, and pH
a 420g mixture of butane and butene is combusted in air to make carbon dioxide and water. if 555 grams of water are
Assume that the Sun and the neutron star are both solid spheres and that angular momentum is conserved during collapse.
Question- A 1.00-g sample of piperazine hexahydrate is dissolved in enough water to produce 100.0 mL of solution and is titrated with 0.500 M HCl.
Calculate the molarity of a solution of glycerol made by dissolving 66.000 mL glycerol at 15 ^circ {rm C} in enough water to make 400.00 mL of solution.
Explain why does the addition of NO2+ to acidic solution of acetanilide require to be performed at a cold temperature. Define what would be the products if this wasn't kept at a cold temperature
Calculate the energy (in eV/atom) for vacancy formation in some metal, M, given that the equilibrium number of vacancies at 404oC is 7.40E+23 m-3. The density and atomic weight for this metal are 15.9 g/cm3 and 65.20 g/mol, respectively.
