1. If one prepared a gas-phase Be3+ ion with its electron in a 4f orbital, it would take the same amount of energy to remove that electron as it does to ionize a ground state H atom. Justify or Refute.
2. If 300 nm light with a certain intensity on a metal surface causes the metal to emit a stream of electrons, then 45- nm light of the same intensity will cause the metal to emit the same number of electrons per unit time, but the emitted electrons will be traveling at a lower speed. Justify or Refute.
3. If a neutral gas-phase atom has a partially filled p subshell in its ground state, all its other subshells are either completely filled or completely empty. Justify or Refute.
As a result of a chemical spill, benzene is evaporating at the rate of 1 gram per minute into a room that is 6 m * 6 m * 3 m in size and ahs a ventilation rate of 10m^3/min. Compute the steady-state concentration of benzene in the room.
Calorimetry is a method used to measure enthalpy, or heat, changes that occur during chemical processes. Two common calorimeters are constant-pressure calorimeters and constant-volume (or "bomb") calorimeters
All of the light is absorbed by the sample. Explain what the overall quantum yield moles reacted is/moles photons for the photochemical process?
Initially, .500 atm of H2 and .500 atm I 2 are mixed in an evacuated 1.0 L flask. The system is allowed to come to equilibrium and it is found tocontain 0.318 atm HI. What is the equilibrium partial pressure of I2 for the reaction shown below?
What is the Kc for the following equilibrium CO2+H2=CO+H2O if CO=0.24M, H2O=0.38m, CO2=0.30M and H2O=3.3*10-2M
What is the molarity of a nitric acid solution if 43.53 mL 0.1000 M KOH solution is needed to neutralize 20.00 mL of the acid solution
Calculate the volume of oxygen,measured at STP, produced by the decompistion of 2.87 g of potassium chlorate.
Presume that methane is an ideal gas the specific heat capacity of water to be constant as well as equal to 4.184 J/g/K over this temperature range as well as the density of water to be 1.0 g/cm3. The combustion of methane is given byCH4 + 2 O2? C..
Would the presence of a nitro group in the 4- and 4'- positions in benzophenone increase the frequency of the carbonyl stretch or decrease it? Explain using resonance structures.
