Give the corresponding atomic orbital designations (that is 1s, 3p, and so on) for electrons with the following sets of quantum numbers: 4,2, -1, -1/2
Find the flux, J, of oil droplets through the water to the top surface. The sink is 18 cm deep, and the concentration of oil on the plate is 0.1 mol/cm3. Assume that there is no oil at the top of the sink when you start. The diffusion coefficient ..
Analysis with an elaborate instrument indicates that substance A contains two elements. Substance B and substance C react to give a new substance D
if a sample of 4.17 L of ethane gas at 725 C is cooled to 175 C at constant pressure, what is the new volume?
How many moles of HF (ka= 6.8 X 10^-4) must be present in 0.200L to form a solution with a pH of 3.25
Use qualitative molecular orbital theory to explain why Na2O2 is diamagnetic and KO2 is paramagnetic (use the appropriate diagram from the notes. Use MO to explain the nature of the oxygen-oxygen bond in the complex anions). What is the oxygen-oxy..
A spring loaded piston cylinder device is initially filled with 0.2 lbm of an R-134a liquid vapor mixture whose temperature is -30 deg F and whose quality is 80 percent. The spring constant in the spring force relation F=kx is 37 lbf/in
Describe the bonding in NCl- using a molecular orbital description. Assume the molecular orbital levels are ordered as in N2. What is the NCl- bond order? How any unpaired electrons are present?
You and your lab partner take melting points of the same sample. You observe a melting point of 101-107°C, while your partner observes a value of 110-112°C. Explain how you can get two different values with exactly the same sample.
Acid rain is caused in part by burning coal that contains sulfur impurities. The sulfur is converted first to SO2, which reacts with oxygen and atmospheric moisture to produce sulfuric acid, H2SO4. If a particular coal contains 2.9% sulfur (by mas..
What is the theoretical yield for this reaction under the given conditions? What is the percent yield for this reaction under the given conditions?
How can diacetylmorphine be ionised in the blood and what will the effects of this be on the molecule in circulation? (I assume that it will be more soluble?)
What is the minimum amount of work the fish must do to compress his swim bladder. Derive the appropriate equation.
