Evaluate the z-component of the angular momentum and the kinetic energy of a particle on a ring that is described by the (unnormalized) wavefunctions e^iΦ ,e^-2iΦ ,cosΦ ,(cosφ)e^iΦ , (sinφ)e^-iΦ
Hex-1-ene, 2-methylpent-2-ene, 2,3-dimethylbut-2-ene, (Z)-hex-2-ene, (E)-hex-2-ene Which one has the highest boiling point and why
a solution formed by dissolving 166.6 grams of common table sugar in 686.2 ml of h2o. compute the vapor pressure at 25
What will be the value of E cell and E0 cell when the Cu/Zn battery has "run down" I.e., reached equillibrium? Also will the concentrations of Zn2+ and Cu2+ be large or small when the battery has "run down"? Does this make sense?
What volume will 1.56 liters of a gas at 27°C and 745 mmHg of pressure occupy at 100°C and 700 mmHg of pressure?
Calculate the [Zn2+] in a solution of ZnC2O4 held at a pH of 3.00. Remember C2O4^2- is a weak base so you must consider other equilibria. (Ksp(ZnC2O4)=7.5X10^-9, Kb1=1.8X10^-10, Kb2=1.8X10^-13).
Determine the percent yield if a student decomposes H 2 O to Form hydrogen (H) and oxygen(O). If the student starts with 34.7 grams of H2O and collects 20.0 grams of oxygen,
If the outer electron in a Sn- ion is removed by absorbing a photon of visible light having an energy of 4.829E-19 J, what is the amount of leftover energy that goes into the kinetic energy of the ejected electron?
The concentration of each gas once equilibrium is reached. The new equilibrium concentrations if the volume is suddenly halved (still at 298K)
An unknown compound contains carbon, hydrogen, oxygen, and sulfur atoms. When a 10.00 mg sample of the unknown compound was combusted, it produced 16.27 mg of CO2, 5.55 mg of water, and 7.90 mg of SO2. What is the empirical formula of the unknown ..
What kinetic energy must the electrons have in order to resolve a protein molecule that is 3.80 nm in diameter? Take the mass of an electron to be 9.11× 10-31 kg.
A spherical fat cell has a diameter of 2.47 micrometers. The fat cell contains three copies of the protein azurin. What is the molar concentration of azurin within the fat cell
