In the Zeeman effect, the energy levels of hydrogen are split by a magnetic field. Each state with a different value of m_l has a different energy. The differences in energy between adjacent values of m_l are all equal. The Zeeman effect is observed as a splitting in the spectral lines of hydrogen in the presence of a magnetic field. What is the greatest number of lines that a single spectral line can be split into by a magnetic field? a)2 b)3 c)4 d)5 e)6
Calculate the concentrations of all species in a 1.62 M Na2SO3 (sodium sulfite) solution. The ionization constants for sulfurous acid are Ka1=1.4x10^-2 and Ka2=6.3x10^-8.
Calculate the percent population of the first 10 rotational energy levels for HBr (rotational constant B = 8.46cm^-1) at 298K?
You performed these reactions in an acidic solution(diluting with 0.1MHNO3). This is because iron forms an insoluble hydroxide even when these solutions do not contain excess hydroxide ion (i.e. even in slightly acidic solutions)
Determine the pressure change when a constant volume of gass at 1.00 atm is heated from 20.0 C to 30.0C.
in the fermentation of glucose wine making a volume of 780 gas was produced at 37 and
Oleum or fuming sulfuric acid available commercially in concentrations ranging from 20 to 99.9% sulfur trioxide.
A solution is prepared by mixing 70.0 mL of 0.010 M BaCl2 and 175 mL of 0.080 M K2SO4. What are the concentrations of barium and sulfate ions in this solution? Assume only SO42- ions (no HSO4? ) are present.
Which of the following solutions has the highest osmotic pressure? A. 1.0 M K3PO4 B. 2.0 M LiBr C. 4.0 M C6H12)6 D. all have the same osmotic pressure
How many hours will it take to produce 47.0 kg of Al metal by the reduction of Al3+ in an electrolytic cell using a current of 487 amps
The lid is tightly sealed on a rigid flask containing 3.50 L H2 at 17 °C and 0.913 atm. If the flask is heated to 71 °C, what is the pressure in the flask?
The heat lost by the boiling water is equal to the heat gained by the room-temperature water. How much heat was transferred in this process
