Write a brief passage describing a neutral atom of nitrogen-14 (N-14). Describe the number of protons, neutrons, and electrons i
2 answers:
Answer: This element contains 7 protons, 7 electrons, and 7 neutrons.
Explanation:
In an atom, there are 3 subatomic particles: protons, electrons, and neutrons.
- Protons: They have a positive charge and are located in the nucleus.
- Electrons: They possess a negative charge and are surrounding the nucleus.
- Neutrons: They carry no charge and are found in the nucleus.
Atomic number represents the total count of protons or electrons in a neutral atom.
Atomic number = number of protons = number of electrons
The mass number is calculated as the overall count of protons plus neutrons present in the atom.
Mass number = Number of protons + Number of neutrons
Atomic mass is derived from the total mass of each isotope multiplied by its natural fractional abundance, which also relates to the number of protons and neutrons in the atom.
Given data:
The element has the formula
Atomic number = Number of electrons = Number of protons = 7
Mass number = 14
Number of neutrons = 14 - 7 = 7
Atomic mass of nitrogen = 14.01 amu
Thus, this element has 7 protons, 7 electrons, and 7 neutrons.

Answer:
The particle's velocity is calculated to be 2 m/s,
Explanation:
Kinetic energy refers to the energy an object possesses due to its movement. The formula for kinetic energy is:
Where:
m = the mass of the object
v = the object's velocity
A particle with mass m has a kinetic energy that is double its mass.
Since the velocity is measured in m/s, we determine that the particle's speed is 2 m/s.
Answer:
Benzoyl Chloride
Explanation:
Friedel-Craft Acylation is a reaction used to incorporate electrophiles (especially carbonyl groups) into the double bonds of aromatic compounds.
This scenario involves synthesizing benzophenone using benzene and benzoyl chloride.
Mechanism:
Step 1: Initially, benzoyl chloride reacts with a Lewis acid to create an electrophile known as oxo(phenyl)methylium.
Step 2: The second stage involves benzene participating in an electrophilic substitution reaction, where the electrophile is added.
Step 3: Finally, the aromatic nature of benzene is restored by releasing a proton.
