Which best explains what happens when an electron moves from an excited state to the ground state? The electron absorbs energy a

s it moves to a lower energy level. The electron absorbs energy as it moves to a higher energy level. The electron releases energy as it moves to a higher energy level. The electron releases energy as it moves to a lower energy level. ANSWER IS : The electron releases energy as it moves to a lower energy level.

Answer and

Explanation

I believe the correct answer would be the last option. When an electrons moves from an excited state to the ground state, it would release energy. An electron in the excited state would mean that it contains high kinetic energy so to move to a lower state some of these energy should be released.

<u>Answer:</u> The value of K_p is 324

<u>Explanation:</u>

We are given:

Initial pressure of S_8(g) = 1.00 atm

The chemical equation for the conversion of S_8(g) to S_2(g) follows:

                  S_8(g)\rightleftharpoons 4S_2(g)

<u>Initial:</u>          1

<u>At eqllm:</u>    1-x       4x

We are given:

Equilibrium partial pressure of S_8(g)=0.25atm

Evaluating the value of 'x', we get:

\Rightarrow (1-x)=0.25\\\\\Rightarrow x=1-0.25=0.75

The expression of K_p for the above reaction follows:

K_p=\frac{(p_{S_2})^4}{p_{S_8}}

p_{S_2}=4x=(4\times 0.75)=3atm

p_{S_8}=0.25atm

Putting values in above expression, we get:

K_p=\frac{3^4}{0.25}\\\\K_p=324

Hence, the value of K_p is 324

Need help asap! A 200 L balloon is blown up inside at 100 K. It is then taken outside in the hot sun and heated to 400K. What is
liq [111]
<h2>Answer</h2>

The volume will be<u> 50 L</u>

<h2>Explanation</h2>

From Kelvin Law of Temperature, we know that

V_{1} T_{1} =V_{2} T_{2}

We know that

V_{1} = 200 L

T_1 = 100 K

T_2= 400 K

So,

V_{2} = V_{1} T_{1}/T_{2}

V_{2} = 200*100/400

V_{2} = 50 L

The answer of the givern question is 50L

An atom that has 13 protons and 15 neutrons is isotope of the element A.) nickel B.) silicon C.) aluminum D.) phosphorus. Why?
joja [24]

An atom that has 13  protons and 15  neutrons  is isotope  of Aluminium (answer C)

<u><em>Explanation</em></u>

  • Isotope  is a form of the same element with   the equal number of protons but difference number  of neutrons  in  their nuclei.
  • In other words isotope has the same  atomic number but different mass  number.
  • Atomic  number of a element is determined by number of  protons of an element.

  • from the  periodic table   Aluminum in atomic number 13 therefore  it has 13 protons  <em>therefore an atom that  has 13  protons and 15 neutrons is   a isotope  of Aluminium. </em>
