Energy is released when an electron transitions from one energy level to another. In contrast, the same amount of energy is needed to carry out the process, the other way around, from the bottom elevation to the upper one.
What occurs when an electron transitions from one energy level to another?
- The energy of the electron drops when it changes levels, and the atom releases photons. The electron emits a photon when it transitions from a greater to a lower energy level. The energy emitted is precisely the energy that is lost when an electron moves to a level with less energy.
- An atom's electrons have negative energy. The electron must be given energy in order to be removed from the hydrogen atom, as shown by the negative sign. The quantity of energy in the atom will rise by supplying the electron with energy. Similar to how a ball on Earth chooses to rest in valleys rather than hills, the electron wants to spend the majority of its time at a lower energy level.
- For a brief period of time, the electron remains in an excited state. The energy required to bring the electron to its lower-energy state will be released when the electron transitions between excited and unexcited states.

Explanation:
Multiplication comes first in BODMAS
Hope it helps
Basically, because the skater will never use some kind of a boost, they will rely purely on forces. At the top of a slope, their kinetic E is zero, and their Potential E is as high as it will be.
The skater will not be able to ever get higher that the initial height without some kind of force helping it.
Al203 is the formula for aluminum oxide
Answer:
[H+]=3.2x10^-6 M 3.2 x 10^-3 mM 3.2 uM
Explanation:
b. Doesn't realy matter but uM would not use exponent of 10
c. 10 times
d. log base 10 2.56 =0.41 log 10^-3 = -3 -3+0.41= -2.59=pH2.59
