100

What are hydrates and how do we name them? 

Water molecules , by using greek prefixes. 

200

What does the word dissociate mean? 

When an ionic compound is placed it water it dissociates, meaning the cations and anions break apart to their individual ionization states. If something dissociates in solution, it is also considered to be soluble in that solution. 

300

Rank the 3 types of intermolecular forces from strongest to weakest

1) H-bonds -Strongest 

2) Dipole-dipole

3) london disperion / Van der Waal - Weakest

400

What is the relationship between polarity and electronegativity? 

The greater the difference in electronegativity between two bound elements, the greater the polarity of the compound
