Answer: Oxygen, Beryllium, Lithium, & Fluorine
Explanation:
theoretically it might not be the answer be
The charge of proton and electron is equal in magnitude that is 
. The distance between electron and proton is 
or 
.
Force exerted on electron by proton is calculated as follows:
Here, k is Coulomb's constant, 
is charge on proton, 
charge on electron and r is distance between them.
Putting the values,
Now, according to second law of Newton,
Here, 
is mass of electron and a is acceleration.
Also, 
Rearranging,
Thus, the acceleration of an electron in this atom is 
.

Explanation:
4NH₃(g) + 5O₂(g) => 4NO(g) + 6H₂O(g)
Ci(NH₃) = 3.5mole/4L = 0.875M
Cf(NH₃) = 1.6mole/4L = 0.400M
Rate-1 => Δ[NH₃]/Δt = |(0.400M - 0.875M)/3min| = 0.158M/s
Rate-2 => 6(Δ[NH₃]/Δt) = 4(Δ[H₂O]/Δt) => 6/4(0.158M/s) = 0.237M/s
Rate-3 => 5(Δ[NH₃]/Δt) = 4(Δ[O₂]/Δt) => 5/4(0.158M/s) = 0.237M/s
_________________________________________________________
NOTE: When setting up comparative rate expressions for a given reaction, set the rates expressions as equal then swap coefficient values. Then solve for rate of interest and substitute givens.
example: for NH₃ and H₂O
- set rates expressions equal => Δ[NH₃]/Δt = Δ[H₂O]/Δt
- then swap and insert coefficients from given rxn ...
- solve for rate of interest ...
4NH₃(g) + 5O₂(g) => 4NO(g) + 6H₂O(g)
=> 6(Δ[NH₃]/Δt) = 4(Δ[H₂O]/Δt)
=> Δ[H₂O]/Δt = 6/4(Δ[NH₃]/Δt) = 6/4(0.237M/s) = 0.237M/s

<h3>The scientific method</h3>
The scientific method refers to systematic methods employed by scientists in their quest for discoveries and explanation of phenomena.
The scientific method includes:
- Observation and formulation of questions
- Developing a hypothesis
- Conducting experiments
- Formulation of theories based on experiments
- Conducting further experiments and research
- Formulation of laws.
Thus, the characteristics of science include:
- relies on evidence
- uses testable ideas
- leads to ongoing research
Therefore, making moral judgments or decisions is not a characteristic of science.
