Physical Science Chapter 8 Lesson 1 Questions

Front

What are the three processes that can occur when substances dissolve?

Back

Dissociation, Dispersion, and Ionization.

Front

Before a solution can form, the attractions that hold the solute together and the solvent together must be ______.

Back

overcome.

Front

Hydrogen chloride, HCl, is a molecular compound in which a hydrogen atom and a chlorine atom share a pair of ______.

Back

electrons.

Front

The process in which an ionic compound separates into ions as it dissolves is called ________.

Back

Dissociation.

Front

When you place a piece of hard candy on your tongue, the sweet taste spreads throughout your mouth by _______.

Back

dispersion.

Front

Define Dissociation in the context of solutions.

Back

Dissociation is the process by which an ionic compound separates into its individual ions when dissolved in a solvent.

Front

What is Dispersion in the context of solutions?

Back

Dispersion is the process of spreading out particles throughout a medium, such as when a solute spreads in a solvent.

Front

What is Ionization in the context of solutions?

Back

Ionization is the process by which a neutral molecule gains or loses electrons to form ions.

Front

What is the role of energy in the dissolution process?

Back

Energy is required to overcome the attractions between solute and solvent particles during dissolution.

Front

Explain the term 'solvent'.

Back

A solvent is a substance that dissolves a solute, resulting in a solution.
