Unit 4 - Properties of Matter - Honors Chem Final Exam Review

Front

What is the formula for calculating density?

Back

Density = Mass / Volume

Front

What are physical properties of matter?

Back

Physical properties can be observed without changing the identity of the substance, such as color, density, and melting point.

Front

What are chemical properties of matter?

Back

Chemical properties describe a substance's ability to undergo chemical changes, such as flammability and reactivity.

Front

How do you determine the density of an object?

Back

To determine density, measure the mass of the object and divide it by its volume.

Front

What is the significance of intermolecular forces in substances?

Back

Intermolecular forces determine the physical properties of substances, such as boiling and melting points.

Front

Which type of compound has the strongest intermolecular forces?

Back

Ionic compounds generally have the strongest intermolecular forces due to the attraction between charged ions.

Front

What is the difference between polar and nonpolar covalent bonds?

Back

Polar covalent bonds have unequal sharing of electrons, while nonpolar covalent bonds have equal sharing.

Front

What is malleability?

Back

Malleability is the ability of a substance to be deformed or shaped under pressure without breaking.

Front

What is conductivity?

Back

Conductivity is the ability of a substance to conduct electricity or heat.

Front

What happens during a chemical reaction?

Back

During a chemical reaction, substances undergo a transformation to form new substances.
