An electron is excited from the n = 1 ground state to the n = 3 state in a hydrogen atom. Which of the following statements is/are true? Correct the false statements to make them true. a. It takes more energy to ionize (completely remove) the electron from n = 3 than from the ground state. b. The electron is farther from the nucleus on average in the n = 3 state than in the n = 1 state. c. The wavelength of light emitted if the electron drops from n = 3 to n = 2 will be shorter than the wavelength of light emitted if the electron falls from n = 3 to n = l. d. The wavelength of light emitted when the electron returns to the ground state from n = 3 will be the same as the wavelength of light absorbed to go from n = 1 to n = 3. e. For n = 3, the electron is in the first excited state.

Solution Summary: The author explains that an electron is excited from the ground level to the excited state of n=3 in a hydrogen atom.
An electron is excited from the n = 1 ground state to the n = 3 state in a hydrogen atom. Which of the following statements is/are true? Correct the false statements to make them true.
a. It takes more energy to ionize (completely remove) the electron from n = 3 than from the ground state.
b. The electron is farther from the nucleus on average in the n = 3 state than in the n = 1 state.
c. The wavelength of light emitted if the electron drops from n = 3 to n = 2 will be shorter than the wavelength of light emitted if the electron falls from n = 3 to n = l.
d. The wavelength of light emitted when the electron returns to the ground state from n = 3 will be the same as the wavelength of light absorbed to go from n = 1 to n = 3.
e. For n = 3, the electron is in the first excited state.
My question is whether HI adds to both double bonds, and if it doesn't, why not?

A certain half-reaction has a standard reduction potential Ered +1.26 V. An engineer proposes using this half-reaction at the anode of a galvanic cell that
must provide at least 1.10 V of electrical power. The cell will operate under standard conditions.
Note for advanced students: assume the engineer requires this half-reaction to happen at the anode of the cell.
Is there a minimum standard reduction
potential that the half-reaction used at
the cathode of this cell can have?
If so, check the "yes" box and calculate
the minimum. Round your answer to 2
decimal places. If there is no lower
limit, check the "no" box..
Is there a maximum standard reduction
potential that the half-reaction used at
the cathode of this cell can have?
If so, check the "yes" box and calculate
the maximum. Round your answer to 2
decimal places. If there is no upper
limit, check the "no" box.
yes, there is a minimum.
