Why is hydride shift favored over methyl shift in rearrangement of free radicals?
takes less energy to move a hydrogen than a methyl
Why would a passing race car display more Doppler effect than a passing police siren?
The amount of Doppler shift depends on speed - the faster vehicle will show more Doppler shift.
The Doppler Effect is a phenomenon that allows one to measure an object's?
The doppler effect is the change in frequency of a wave for an observer moving relative to the source of the wave. You can measure the location and velocity of a locomotive moving towards or away from your. You can measure a star's location and velocity vector regarding the shift and color emanating from the star light. This is calculated via doppler light equations.
What do scientist do when things are to small or big to study?
Nothing is too small or too big to study. Usually if you cannot see the thing you are studying you look for it's effect on other things- for example we cant see the universe expanding but we know it happens because of Red Shift.
What is the apparent shift in measurement is called?
parallax
Why is hydride shift favored over methyl shift in rearrangement of free radicals?

Will the total number of electrons change when a specific element's electrons gain energy to shift from the ground state to the excited state?
No. The atom in this case i not ionised.
How Magnetic fields affect the alignment of electrons in an atom?
Magnetic fields can influence the alignment of electrons in an atom by exerting a force on the charged particles, causing a shift in their orientation. This can lead to changes in the energy levels and behavior of the electrons within the atom. The Zeeman effect, for example, describes how magnetic fields can split spectral lines in the presence of an external magnetic field, providing insights into the orientation of electrons.
What is the red shift of hydrogen?
The red shift depends on the relative motion of the emitting source and receiving detector. Hydrogen per se has no red shift. There is hydrogen with great red shift (in stars in galaxies far away that are moving rapidly away from us).
How do you determine the velocity of an electron?
X-rays are reflected by electrons. The shift in frequency/wavelength of the reflected X-ray compared to the original X-ray (Doppler effect) can be used to measure the speed of the electrons.
Why is it that all of the sub shells in a given shell have the same energy in the hydrogen atom whereas in a many-electron atom the sub shells in a given shell do not have the same energy?
The hydrogen atom only has one energy level (shell). The first energy level also contains only one sublevel, 1s sublevel (subshell), which can only hold two electrons. When you get to the second energy level in the second period on the periodic table, it has two sublevels, the 2s and the 2p sublevels. Both of the electrons in the 2s sublevel have the same energy. The 2p sublevel can hold 6 electrons. All of the electrons in the 2p sublevel have the same energy, which is higher than the energy in the 2s sublevel. So, as we move down the periods on the periodic table, we move from the first energy level to the seventh energy level. Each energy level contains specific numbers of sublevels, and all of the atoms within a particular sublevel have equal energy.
What advancements in technology is gaining a hydrogen reduction and how will it impact the future of energy production?
Advancements in technology, such as electrolysis and hydrogen fuel cells, are gaining traction in hydrogen reduction. This process involves using renewable energy sources to split water molecules into hydrogen and oxygen. The hydrogen can then be used as a clean and efficient energy source for various applications, including transportation and electricity generation. This shift towards hydrogen-based energy production has the potential to reduce greenhouse gas emissions and dependence on fossil fuels, leading to a more sustainable and environmentally friendly future.
Differentiate between photoelectric effect and florescence?
Photoelectric Effect is the emission of electrons by substances, especially metals, when electromagnetic radiations such as x-rays or visible light, of certain minimum frequency, fall on their surfaces. If the energy (from EM Radiations) absorbed is more than the ionization energy then electrons will be emmitted. The emitted electrons can be referred to as photoelectrons in this context.The effect was discovered by H. R. Hertz in 1887. The effect is also termed the Hertz EffectFluorescence is a luminescence that is mostly found as an optical phenomenon in cold bodies, in which the molecular absorption of a photon triggers the emission of another photon with a longer wavelength. The energy difference between the absorbed and emitted photons ends up as molecular vibrations or heat. Usually the absorbed photon is in the ultraviolet range, and the emitted light is in the visible range, but this depends on the absorbance curve and Stokes shift of the particular fluorophore. Fluorescence is named after the mineral fluorite, composed of calcium fluoride, which often exhibits this phenomenon.
How do you demonstrate the red shift and Doppler effect?
Examine the light of hydrogen emissions from a distant galaxy. Compare that spectrum with that of hydrogen in a laboratory. You'll find that spectrum is identical EXCEPT that it is shifted towards longer wavelengths.
What effect is red shift an example of?
The Doppler effect.
What are red shift and blue shift in UV spectroscopy?
The solvent in which the absorbing species is dissolved also has an effect on the spectrum of the species. Peaks resulting from n ® p* transitions are shifted to shorter wavelengths (blue shift) with increasing solvent polarity. This arises from increased solvation of the lone pair, which lowers the energy of the n orbital. Often (but not always), the reverse (i.e. red shift) is seen for p ® p* transitions. This is caused by attractive polarisation forces between the solvent and the absorber, which lower the energy levels of both the excited and unexcited states. This effect is greater for the excited state, and so the energy difference between the excited and unexcited states is slightly reduced - resulting in a small red shift. This effect also influences n ® p* transitions but is overshadowed by the blue shift resulting from solvation of lone pairs.
What would happens to high energy electrons and hydrogen held by NADH if there is no O2 present?
Without oxygen present, high-energy electrons from NADH cannot be passed down the electron transport chain for ATP production through oxidative phosphorylation. This can lead to a buildup of NADH and a decrease in the availability of NAD+ for glycolysis and the Krebs cycle. As a result, the cell may shift to less efficient processes like fermentation to regenerate NAD+ and keep glycolysis running.
