Molecular Shape
This molecular shape has a central atom with 4 substituents and 0 lone pairs
What is tetrahedral?
If the central atom contains this, then you know it's a polar molecule even if you do not know its elemental composition
What is a lone pair of electrons?
The attractive force that enables salt to dissolve in water
What is ion - dipole forces?
When molecules in a substance have a stronger attraction to each other, more of this is needed to convert the substance into a gaseous phase
What is heat energy?
If calcium carbonate has a solubility in water of 15 mg/L, then this is the type of solution that forms when 30 µg of calcium carbonate is added to 0.5 kL of water
What is an unsaturated solution?
This molecular shape has a central atom with 2 substituents and 0 lone pairs
What is linear
These two molecular shapes are always polar molecules
What are bent and triangular pyramidal?
The attraction between HCN molecules
What are dipole - dipole forces?
Molecules attracted to each other by induced dipole - induced dipole forces tend to have this type of boiling point compared to molecules attracted to each other by dipole - dipole forces (assuming similar size and shape)
What is a lower boiling point?
The percent concentration of a solution made of 8.5 g NaCl and 122.3 g H2O
What is 6.5%?
This molecular shape has a central atom with 3 substituents and 0 lone pairs
What is triangular planar (trigonal planar)?
Another way of saying "polar molecule" is by saying a "molecule that contains a ____"
What is a dipole?
The attraction between water molecules
What are hydrogen bonds?
Larger nonpolar atoms and molecules tend to have this type of boiling point compared to smaller nonpolar atoms and molecules
What is a higher boiling point?
This many molecules of sucrose are in 1.0 L of a 0.50 M aqueous sucrose solution
What are 3.0×1023 molecules?
This molecular shape has a central atom with 4 substituents and 1 lone pair
What is triangular pyramidal (trigonal pyramidal)?
Carbon dioxide contains this type of bond and is this type of molecule
What are polar bonds? And what is a nonpolar molecule (linear, AB2)?
The attraction between carbon dioxide molecules
What are induced dipole - induced dipole forces?
The following substances from highest to lowest boiling point: water, magnesium oxide, diatomic oxygen, and carbon dioxide
What is magnesium oxide, water, carbon dioxide, and diatomic oxygen?

What is 1.7 M?
This molecular shape has a central atom with 3 substituents and 1 lone pair
What is bent?
Dichlorine monoxide contains this type of bonds AND is this type of molecule
What are a nonpolar bonds? And what is a polar molecule (bent, AB2E2)?
A polar molecule can induce this in a nonpolar molecule due to proximity
What is a temporary dipole?
