Electron transfers between energy levels.

<h3>Explanation</h3>

An atom contains an infinite number of energy levels. An electron can exist within any one of them, but not in between. Electron can move from one level to another. However, those levels differ in energy. Energy has to conserve.

  • An electron loses energy when it moves to a level of lower energy. The energy is released as radiation. The frequency of the radiation depends on the energy difference. Those radiations combine to produce an emission spectrum.
  • An electron gains energy when it moves to a level of higher energy. This transfer happens only if there's an external source of energy. For example, directing a beam of white light on the atom. The beam of light would excite the electron. Again, the frequency of the radiation depends on the energy difference. Only frequencies that corresponds to transfer will be absorbed. Those radiation will eventually be released in all directions. As a result, strength of some of the radiations will be weakened. A continuous spectrum with those frequencies weakened is an absorption spectrum.

Identify the reactants in the equation: 6C0, + 6H2O - CHUO+ 60,
Effectus [21]

Answer:

The correct answer is d. 6H20 + 6CO2.

The reactant in the chemical reaction 6H2O + 6CO2 ---> C6H12O6 + 6O2 is 6H20 + 6CO2. Remember that the reactant is always at the left side of the equation. So the correct answer is 6H20 + 6CO2 since it's in the left of the equation. I hope this answer helped you.

Mg2OH has how many unique elements?<br> A. <br> 4<br> B. <br> 2<br> C. <br> 3<br> D. <br> 5
frutty [35]

Answer:

Magnesium hydroxide has 3 unique elements.

Explanation:

Long story short, 2 is the balancing compound in structure to make up hydroxide, therefore 1 compound would be left to create Mg(2O)H.

(This is only an opinion of mathematical science to me, I don't have complete understanding of this subject either, good luck.)

Which half reaction can occur at the abode in a voltaic cell?
Digiron [165]
The oxidation half-reaction occurs at one electrode (the anode), and the reduction half-reaction occurs at the other (the cathode). When the circuit is closed, electrons flow from the anodeto the cathode.
