Unsaturated

Front

Which type of compound has the lowest melting point?

Back

Molecular compounds

Front

What is sublimation?

Back

Sublimation is when a solid changes directly into a gas, due to weak dispersion forces.

Front

Which of the following dissolves in water: Potassium Chloride (KCl), Hexane (C6H14), Methane (CH4), or Sand (SiO2)?

Back

Potassium Chloride (KCl) dissolves in water.

Front

What does the triple point of a phase diagram represent?

Back

The triple point shows where a gas, solid, and liquid exist at equilibrium.

Front

Define solubility.

Back

Solubility is the ability of a substance to dissolve in a solvent at a given temperature and pressure.

Front

What is the difference between saturated, unsaturated, and supersaturated solutions?

Back

Saturated: maximum solute dissolved; Unsaturated: less than maximum solute; Supersaturated: more than maximum solute.

Front

What type of bond is present in ionic compounds?

Back

Ionic bonds are formed by the electrostatic attraction between oppositely charged ions.

Front

What is the significance of the melting point in substances?

Back

The melting point is the temperature at which a solid becomes a liquid.

Front

What are molecular compounds?

Back

Molecular compounds are formed when atoms share electrons through covalent bonds.
