See explanation
Explanation:
Potential energy here refers to energy that exists as a result of the relative position of the particles in a system.
Between figures 1 and 2 the potential energy of the system increases since the like charges repel when the distance between them is reduced.
Similarly, between 3 and 4, the potential energy of the system decreases since like charges attracts each other. Potential energy is inversely proportional to the force of attraction between the opposite charges hence potential energy decreases with decrease in distance.
The potential energy of the system decreases even more when one charge is +2 and the other is -1.

The size of an atom would be described in _______.
Answers
Answer:
atomic radius
Explanation:
so radius
Answer:
Explanation:
The average size of an atom is about 100 picometers or one ten-billionth of a meter. Almost all of the mass of an atom is in its nucleus; almost all of the volume of an atom is occupied by electrons. The number of protons (also known as its atomic number) determines the element. Varying the number of neutrons results in isotopes.

Answers
Answer: D- A seed that contains an embryo plant grows into a young pine tree.
Explanation: The embryo plant comes from a pinecone seed so it can grow into a new plant.
The stage labeled 6 is a seed that contains an embryo plant grows into a young pine tree. The correct option is D.
What is a plant embryo?Plant embryonic development, also known as plant embryogenesis, is the process that occurs after an ovule is fertilized to produce a fully developed plant embryo.
This is an important stage in the plant's life cycle, following dormancy and germination.
Embryogenesis occurs naturally as a result of ovule fertilization, giving rise to two distinct structures: the plant embryo and the endosperm, both of which develop into seeds.
In order to produce a mature embryo, the zygote goes through several cellular differentiations and divisions.
The sixth stage is a seed containing an embryo plant that grows into a young pine tree.
Thus, the correct option is D.

why is the symbol [Ar] used in the electron configuration of potassium, and what does it represent?
Answers
Answer:
To denote a stable inner configuration and it represents argon
Explanation:
The symbol [Ar] used in the electron configuration of potassium represents the inner electronic configuration of the element.
This argon atom is stable octet with completely filled shells. Most noble gases are used to write the electronic configuration of other atoms. The inner atomic orbitals of elements are similar to those of nearby noble gases.
Ar is Argon with a configuration of 1s² 2s² 2p⁶ 3s² 3p⁶So, this configuration is stable and it the inner configuration of potassium excluding the outermost orbitals.Step 6: Measuring the Volume of Air Near 40°C

The volume using the cylinder formula : V=πr²h
Further explanationCharles's Law
When the gas pressure is kept constant, the gas volume is proportional to the temperature
[tex]\tt \dfrac{V_1}{T_1}=\dfrac{V_2}{T_2}[/tex]
This experiment is an illustration of Charles's law, to determine the relationship between temperature and gas volume
If a certain amount of gas is heated, the volume will increase
So in this experiment, the temperature was changed as an independent variable and tube volume as a fixed variable
Because the tube is cylindrical, to find the volume using the cylinder formula
[tex]\tt V=\pi.r^2.h[/tex]
Meanwhile, to find the radius, you can use a caliper to measure the diameter of the tube and the result will be divided by 2

Under which conditions does a real gas behave most like an ideal gas? A. At low temperatures and high pressures B. At low temperatures and low pressures C. At high temperatures and high pressures D. At high temperatures and low pressures
Answers
Answer: D. At high temperatures and low pressures
Explanation:
At low temperature and high pressure, the kinetic energy of gas molecules is negligible and molecules will have negligible forces of attraction. So real gases will behave least like an ideal gas under such conditions.
At high temperature and low pressure, energy due to intermolecular forces becomes less important in comparison to the kinetic energy of particles. The size of molecules also become less significant than the empty space between the gas molecules. So real gases behave in a similar manner to ideal gases at high temperature and low pressure.

what is the reaction type of 3ZnS+ 2AlP = 1Zn3P2 + 1Al2S3 ?
Answers
Answer: double displacement
Explanation:
A double displacement reaction is one in which exchange of ions take place. The salts which are soluble in water are designated by symbol (aq) and those which are insoluble in water and remain in solid form are represented by (s) after their chemical formulas.
The balanced chemical equation is:
[tex]3ZnS+2AlP\rightarrow Zn_3P_2+Al_2S_3[/tex]
Thus as ions get exchanged , it is double displacement reaction.
