When a solution forms, what interactions between particles are involved? Which are exothermic? Which are endothermic? please explain

Answers

Answer 1
Answer:

Answer:

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 .
Answer 2
Answer:

Final answer:

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.

Explanation:

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.

These models show the electron structures of two different nonmetal elements.Which element is likely more reactive, and why?A.) Element 1 is more reactive because it has fewer electron shells and is toward the top of its group on the periodic table.B.) Element 1 is more reactive because it has more electrons in its valence shell and is farther to the right on the periodic table.C.) Element 2 is more reactive because it does not have a valence shell close to the nucleus, so it will attract electrons.D.) Element 2 is more reactive because it does not have a full valence shell, so it will attract electrons.
