Intermolecular Forces
What is the primary intermolecular force in methanol (CH₃OH)?
Hydrogen Bonding
What is it called when a gas turns into a liquid?
Condensation
What is the formula of the ionic compound formed from aluminum and oxygen?
Al₂O₃
As IMF increase, does boiling point increase or decrease?
Increase
When a solid turns into a liquid, or a liquid turns into a gas, what value is increasing in the system?
Entropy (disorder)
What crystalline solid would you classify table salt as?
Ionic
Which substance has the lowest boiling point?
a. CI₄
b. CBr₄
c. CH₄
d. CCl₄
c. CH₄
What is it called when a gas turns into a solid?
Deposition
If one unit cell of an unknown element contains only a body centered and face centered atoms on all sides, how many atoms are there per unit cell? (This question is very confusing without a picture, so if you'd like me to draw one please let me know!)
4
If a substance has strong IMF, does it have high or low vapor pressure?
Low Vapor Pressure
What is it called when a solid turns into a gas?
Sublimation
If the formula of an ionic bromide of element X is XBr, what is the formula of the oxide of X?
X₂O
Is surface tension affected by IMF? Why or how?
Yes, a substance with strong IMF has greater surface tension because of how strongly molecules at the surface attract each other.
On a phase diagram, what is the unique temperature and pressure at which a substance’s solid, liquid, and gas phases all coexist in equilibrium called?
The Triple Point
What does it mean when a substance is amorphous?
The atoms of the substance are arranged more like the atoms in a liquid, but they cannot flow past each other.
