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 can't the reaction, ZnCl2 + H2 → Zn + 2HCI, occur naturally?
Llana [10]

Answer:

It is fairly obvious that zinc metal reacts with aqueous hydrochloric acid! The bubbles are hydrogen gas. ... In fact, electrons are being transferred from the zinc atoms to the hydrogen atoms (which ultimately make a molecule of diatomic hydrogen), changing the charges on both elements.

If you go from the Earth to the Moon, will your MASS change?
Solnce55 [7]

Answer:

No matter if you are on Earth, the moon or just chilling in space, your mass does not change. But your weight depends on the gravity force; you would weigh less on the moon than on Earth, and in space you would weigh almost nothing at all.

Which is not a reason why mass of an atom is expressed in atomic mass units rather than in grams?
Tasya [4]
What are your answer choices? Scientists express the weight in AMU’s so that they can easily think about the weight of the atom. If it is expressed in grams, they’re constantly dealing with a weight that’s around 10^-24 grams, which is hard to deal with.

What volume of 7.25 mol/L stock solution in needed to make 3.84 L of 8.50 mol/L solution?
Serjik [45]

Answer:

4.50 L

Explanation:

First we <u>calculate how many moles are there in 3.84 L of a 8.50 mol/L solution</u>:

  • 3.84 L * 8.50 mol/L = 32.64 mol

Now, keeping in mind that

  • Concentration = Mol / Volume

we can calculate the volume of a 7.25 mol/L solution that would contain 32.64 moles:

  • Volume = Mol / Concentration
  • Volume = 32.64 mol ÷ 7.25 mol/L
  • Volume = 4.50 L

So we could take 4.50 L of the 7.25 mol/L solution and evaporate the solvent until only 3.84 L remain.
