Answer:
I interpret the answers as being nonmetallic and metallic.
Explanation:
Nonmetals are in groups 14 - 18. Electronegativity is referred to as the want to attract electrons to an atom. Noble gases (group 18) have eight valence electrons in their outer subshells and are therefore atomically stable. Elements with only 7 valence electrons are very electronegative because they desire to obtain an electron to reach stability more than a group 2 element would (they are more likely to drop electrons by giving away in order to reach atomic stability of a group 18 element). This coincides with electron configuration, which is a very lengthy topic to cover. You can conduct more research if you would need it.
B. The theory might be modified if necessary.
C. Bernoulli will come up with another hypothesis.
D. Bernoulli's principle will be called "Bernoulli's hypothesis."
Bernoulli's principle is a theory given the name "principle" because _____.
A. it is actually more like a hypothesis
B. nearly all scientists agree that it is correct
C. it is one of the first things you would learn about in college
D. you can't provide evidence for it, but scientists know that it is correct
Answer:
B. The theory might be modified if necessary.
B. nearly all scientists agree that it is correct
Explanation:
B. The theory might be modified if necessary.
The Bernoulli's principle relates the speed of fluid to their pressures. It simply states that when the speed of fluids increases there is a drop in pressure.
Supposing we find new evidence about how the principle works, the normal scientific thing to do is to modify the existing principle. New information and observations about a principle would only provide a modification to the existing one. An example is the Dalton's atomic theory, which was centered on the atom being the smallest indivisible particle: the theory was later modified when new ideas about the atom surface.
B. nearly all scientists agree that it is correct
Before a hypothesis is adopted to the context of scientific principle, the ideas behind it must have tested and must be repeatable. Different sources will verify the authenticity of such scientific claim to see if such can be adopted. Therefroe, nearly a large numbr of scientists must agree that it is correct.

Explanation:
There are three types of interactions involved between the particles when solution are formed.
1 : Solute - solute interaction:
2 : Solute - solvent interaction:
3 : Solvent - solvent interaction:
1 : Solute - solute interaction:
It is the inter-molecular attraction between the solute particles.
2 : Solute - solvent interaction:
It involve the inter-molecular attraction between solvent and solute particles.
3 : Solvent - solvent interaction:
It involve the intermolecular attraction between solvent particles.
Solutions are formed if the intermolecular attraction between solute particles are similar to the attraction between solvent particles.
Exothermic process:
The process will exothermic when solute solvent bonds are formed with the release of energy and energy required to brake the solute-solute particles and solvent solvent particles are less.
Endothermic process:
The process will be endothermic when energy required to break the solute-solute particles and solvent solvent particles are higher than energy released when solute solvent bonds are formed .
Solution formation involves three particle interactions: solute-solute, solvent-solvent, and solute-solvent interactions. Breaking solute-solute and solvent-solvent interactions requires energy, so these are endothermic processes. Solute-solvent interaction formation releases energy, making it an exothermic process.
When a solution forms, three main types of interactions between particles are involved: solute-solute interactions, solvent-solvent interactions, and solute-solvent interactions. The formation of a solution is essentially a sort of balance between these interactions.
Solute-solute interactions are the attractions between particles (atoms, molecules, or ions) within the solute. The breaking of these attractions is an endothermic process, as it requires energy to be put into the system to overcome these attractions.
Solvent-solvent interactions are the attractions between particles within the solvent. Like solute-solute interactions, the breaking of solvent-solvent interactions is also an endothermic process.
Solute-solvent interactions occur between particles of the solvent and solute when a solution is formed. This is the point at which the solvent 'dissolves' the solute. The formation of these new attractions releases energy, making it an exothermic process.

When Elisya blows harder with the bubble blower, she increases the air pressure and thus the bubble's size due to resistance against the surface tension of the water. Additionally, the soap bubble's film thickness changes, altering light path differences and possibly the perceived color of the bubble.
When Elisya blows harder on the soup with the bubble blower, the soup water may experience changes due to increased air pressure. This air adds stress to the surfaces of the water which can cause a bubble to form as the surface tension of the water attempts to decrease the surface area.
The surface tension of the water inside the soap bubble tries to contract the bubble into the smallest possible surface area. When Elisya blows more air into the soap bubble, she is effectively increasing the volume of the air inside the bubble. This results in an increased bubble size, as the internal air pressure works against the surface tension trying to minimize the bubble's surface area.
Also, the formation of soap bubbles has to do with the properties of thin films and light interference which are evident when we see distinct colors on the soap bubbles. When Elisya blows harder through the soap bubble blower, the thickness of the bubble's film changes, altering the path length difference and interferences of light, which could potentially change the colors we perceive in the bubble.
