Assignment:
1. Please explain how ionization energy changes between the atoms when we move across the row or column in periodic table? How can we relate this to eigenstates of hydrogen atom? What is the fraction dependence of hydrogen atom eigen states that explains the ionization change across a row? How does actual dependence change from that expected from hydrogen atom? What is the physical origin of this difference?
2. In hydrogen atom energy levels (W) with different m are degenerate. Yet while filling 2Px, 2Py and 2P2 of boron, carbon and hydrogen we first fill different p orbitals with one electron before filling same p orbital with 2 electron. Explain why?
3. Ionization energy changes in second row in periodic table in a non monotonic way. Explain why ionization energy drops from Be to B and then from N to O?
A student carried out this reaction in a eudiometer in hopes of measuring the Ideal Gas Law Constant, R. The gas collected in the eudiometer displaced water (just like in your experiment). She allowed the reaction to proceed for 10 minutes and coll..
Question- A compound of C, H, and O was burned in oxygen, and 1.000 g of the compound produced 1.418 g CO2 and .871 g H2O. In another experiment, .1103 g of the compound was dissolved in 45.0 g of water. This solution had a freezing point of -.073..
Draw the condensed formulas for each of the following compounds: (a) dipropyl ether (b) 2,2-dimethyl-3-hexanol (c) 2-ethoxybutane
The Kp for the reaction is 4.3X10^-4 at 648K. Determine the equilibrium partial pressure of NH3 in a reaction vessel that initially contained 0.900atm N2 and 0.500 atm H2 at 648K
A company is considering purchasing an equipment for $53,640. Shipping and installation costs would cost another $2,857.
suppose you have an electric hot water heater for your house which is an aluminum cylinder which has a 0.56 m radius
A blood sample has an [H3O+]= 4.6 x 10^-8. Show how to determine (and then calculate) the pH, pOH, and [OH-] of this blood sample. In addition, determine if this blood sample is acidic, neutral, or basic and indicate if the pH of this sample is wi..
If 125 g XeF[2](s) reacts completely and the gas is collected in a 50.0 L flask at 300 K, what is the pressure of the gas in atmosphere. XeF[2](s) + H[2]O(l) ---> 2Xe(g) + O[2](g) + 4HF(g)
Problem- Propose a reason for why 2,4-DNP or semicarbazone derivates usually precipitate out of their ethanolic solutions.
Problem- If the water in your house has 1000.0 mg/L of calcium carbonate dissolved in it, How many grams of sodium oxalate could you mix with 100.0 mL of that water before a precipitate would form
The equilibrium constant Kc equals .0952 for the reaction at 227C CH4OH(g) CO(g)+ 2H2(g). wHAT us the value of KP at this temperature
