Final Exam Review II_General Chemistry I

Front

What is a characteristic property of metallic solids?

Back

Metallic solids exhibit high thermal and electrical conductivity, variable melting points, and variable hardness, but they are not brittle.

Front

What is the oxidation number of sulfur (S) in H2SO4?

Back

The oxidation number of sulfur in H2SO4 is +6.

Front

Is oxygen a diamagnetic or paramagnetic substance?

Back

Oxygen is a paramagnetic substance due to the presence of unpaired electrons.

Front

How do you calculate molality (m) of a solution?

Back

Molality (m) is calculated as moles of solute per kilogram of solvent.

Front

How do you calculate molarity (M) of a solution?

Back

Molarity (M) is calculated as moles of solute per liter of solution.

Front

What is the formula for calculating the number of atoms in a face-centered cubic unit cell?

Back

Front

What is the significance of the molecular orbital diagram in determining magnetic properties?

Back

The molecular orbital diagram helps identify the presence of unpaired electrons, which determines if a substance is diamagnetic or paramagnetic.

Front

What is the difference between molarity and molality?

Back

Molarity is moles of solute per liter of solution, while molality is moles of solute per kilogram of solvent.

Front

What does it mean for a substance to be paramagnetic?

Back

A paramagnetic substance has unpaired electrons and is attracted to a magnetic field.

Front

What does it mean for a substance to be diamagnetic?

Back

A diamagnetic substance has all paired electrons and is slightly repelled by a magnetic field.
