Which of the following best describes how an electron moves when it absorbs or releases exact amounts of energy?

Chemistry

Answer: The correct option is B.

Explanation: As the electron moves from lower energy level to higher energy level, it absorbs some amount of energy. When the electron returns back from this higher energy level to the lower energy level, it emits the exact  amount of energy it has absorbed.

As every orbital has its characteristic energy value, whenever electrons absorb or emit energy, they move to different energy level that is they occupy different orbitals and hence we can say that the electron moves between orbital levels.

Why does the sun seem to change position in the sky?
Blababa [14]

The first major contributor to the Sun's apparent motion is the fact that Earth orbits the Sun while tilted on its axis. The Earth's axial tilt of approximately 23.5° ensures that observers at different locations will see the Sun reach higher-or-lower positions above the horizon throughout the year.

hope this helps ^^

In tne equation below identify the bronsted lowry acid bronsted lowry base conjugate acid conjugate base
Ad libitum [116K]

Answer:

  • <em>Brønsted-Lowry acid: HNO₂</em>
  • <em>Brønsted-Lowry base: NH₃</em>
  • <em>Conjugate acid: NH₄⁺</em>
  • <em>Conjugate base: NO₂⁻</em>

Explanation:

The equation is:

                 HNO_2(aq)+NH_3(aq)\rightarrow NH4^+(aq)  + NO2^-(aq)

<em>Brønsted-Lowry acids</em>  are H⁺ donors.

<em>Brønsted-Lowry bases</em> are H⁺ acceptors.

Thus, on the left side, <em>HNO₂</em> is the acid and <em>NH₃ </em>is the base.

The <em>conjugate acids</em> and <em>conjugate bases</em> are on the right side of the equation.

The <em>conjugate acid</em> is the spieces that is formed after a base accepts the proton; thus it is <em>NH₄⁺</em>. A <em>conjugate acid</em> contains one more H atom and one more + charge than the base that formed it.

The <em>conjugate base</em> is the species that is formed after the acid donates its proton; thus, <em>NO₂⁻</em> is the <em>conjugate base</em>. A <em>conjugate base</em> contains one less H atom and one more - charge than the acid that formed it.

Summarizing:

  • Brønsted-Lowry acid: HNO₂
  • Brønsted-Lowry base: NH₃
  • Conjugate acid: NH₄⁺
  • Conjugate base: NO₂⁻

What do voltage-gated ion channels open in response to?.
Pavlova-9 [17]

Answer:Voltage-gated channels open (activate) in response to changes in membrane potential because the electric field acts on the channel to change its protein conformation (or state). It is voltage-gated sodium (Na+) channels that initiate action potentials and voltage-gated K+ channels that cause them to end.
