Prepare a molecular orbital energy level diagram for NO, showing clearly how the atomic orbitals interact to form MO's
a) How does the diagram illustrate the difference in electronegativity between N and O?
b) Predict the bond order and number of unpaired electrons
c) NO+ and NO- are also known. Compare the bond orders of these ions with the bond order of NO. Which of the three would you predict to have the shortest bond? Why?
Draw the structure of the one alkene which upon treatment with O2 followed by Zn and acid, would give rise to formaldehyde and cyclohexanone
Calculate the lattice energy for the hypothetical ionic compound M2X from the information given below. IE1(M) = 424 kJ/mol M(s) => M(g) ?Ho = 84.3 kJ/mol ?Hof(M2X) = -888.3 kJ/mol X2(g) => 2X(g) ?H = 231 kJ EA1+EA2 (X) = 476 kJ/mol IE1 (X) = 271 k..
Calculate the mass of ethylene glycol (C2H6O2) that must be added to 1.00 kg of ethanol (C2H5OH) to reduce its vapor pressure by 10.0 torr at 35 °C. The vapor pressure of pure ethanol at 35 °C is 1.00 × 10^2 torr.
How many liters of CO2 are formed at STP by the complete combustion of the propane in a container with a volume of 14.0L and a pressure of 4.5atm at 24?C?
The amount of carbon dioxide in a gaseous mixture of CO2 and CO can be determined by passing the gas into an aqueous solution that contains an excess of Ba(OH)2
A mixture of liquid hydrogen and water (99.99 mole %) is in equilibrium with hydrogen gas and water vapor at 25°C. Assuming ideal solution behavior, calculate the system pressure and the molar composition of the gas phase.
The volume of potassium permanganate required to titrate 10 mL of the new hydrogen peroxide (mL):20mL (c) Calculate the concentration of H2O2 from the volume of KMnO4 used and the stoichiometry of the reaction (MW of H2O2 is 34.01).
a smaller amount of A would remain in the water than if the solution were extracted with one 50mL portion of diethyl ether.
calculate the atomic mass of an element with a measure specific heat of 0.14 J/(g C). Express your answer in atomic mass units to two significant figures.
What concentration of Benzoyl peroxide (k_d = 1.45 * 10^(-6) L/mol-s, 60 deg C) would be needed to polymerize a 1.00 M solution of styrene to a molecular weight of 2500
The mixture did not rotate the plane of polarized light before. How had the mold changed the solution to become optically active?
