When a solid dissolves in a liquid to form a solution, solid particles become evenly dispersed among liquid particles.
<h3>What are solutions?</h3>
Solutions are formed when a solute particle dissolves in another substance known as a solvent.
Usually, solutions are formed when solids dissolve in liquids.
The solid is the solute while the liquid is the solvent.
When a solid dissolves in a liquid, solid particles become evenly dispersed among liquid particles.
Therefore, solutions are formed when solute particles dissolve in solvents.

The 02 is a solid. I hope thus helped you :)
Answer:
C. They don't react with other elements to form compounds
Explanation:
The elements in Group 18 of the periodic table are called "inert", or noble gases.
These elements have their valence shell (the outermost shell of the atom) full of electrons, so they do not gain/give off electrons, and therefore, they do not react with other elements, so they do not form compounds.
In fact, normally the elements try to gain/give off electrons in order to fullfill their outermost shell (the valence shell). For instance, an atom that has 1 electron only in its valence shell, try to "give away" this electron in order to have its outermost shell completed. On the other hand, an atom which has 7 electrons in its valence shell tries to "gain" one electron in order to fullfill the valence shell.
Noble gases, instead, have already 8 electrons in their valence shell, so their valence shell is already completed, therefore they do not react with other elements, and therefore they are called "inert".
Answer:
1 marcomolecules are:- A macromolecule is a very large molecule, such as a protein. They are composed of thousands of covalently bonded atoms. Many macromolecules are polymers of smaller molecules called monomers.
2 polymers are:- a natural or artificial chemical compound consisting of large molecules

Answer:
S (Sulfur)
Explanation:
Electronegativity increases as you go up and right on the periodic table, excluding the noble gases on the rightmost column because they have zero electronegativity. S is the farthest right out of all the elements listed in the question excluding Ne.
