Vinegar dissolve in water but oil does not because vinegar is polar like water, but oil is nonpolar and the correct option is option C.
The dissolving process depends on the polarity of the substances involved. Water is a polar molecule, meaning it has a positive and negative end, while vinegar contains acetic acid, which is also polar. Since both water and vinegar are polar, they can mix and dissolve in each other easily.
On the other hand, oil is nonpolar, meaning it lacks a positive and negative end. Because of this, oil cannot dissolve in water, which is polar. Instead, oil and water will separate into distinct layers. This phenomenon is due to the "like dissolves like" rule, where polar substances dissolve best in polar solvents and nonpolar substances dissolve best in nonpolar solvents.
Thus, the ideal selection is option C.

b.twice the sum of the pressures that are exerted by the individual gases.
c.the sum of the pressures that each gas would exert if they occupied twice the volume.
d.the sum of the pressures that each gas would exert if they occupied half the volume.
Answer: The correct option is (a).
Explanation:
If two gases are present in a container, the total pressure in the container is equal to the sum of the all the individual pressures exerted by the individual gases in a container.
Individual pressure exerted by the individual gas in a container is called partial pressure of that individual gas.
So, total pressure of gas in container is:
Where = Total pressure exerted by the gases in the container.
= Partial pressure of gas 'a'
= partial pressure of gas 'b'
The answer is a, because the question is referring to partial pressures. Partial pressures are a mere sum, no halving or doubling of anything is necessary.
So, A

B)nuclear binding C)energy
D)nuclear forces
Answer:The correct answer is 'nucleons'.
Explanation;
An atom is a structural unit of matter.It consist of three subatomic particles: electrons, protons, and neutrons.
Protons and neutrons are located at center of an atom where whole mass of an atom is concentrated that is in the nucleus of a atom.
Protons and neutron being located in nucleus are also known as nucleons.
Where as electrons revolve around the nucleus in different orbits inside an atom.
Hence, the correct answer is 'nucleons'.
b. 3.0
c. 0.20
