    All matter is subject to attractive forces, though we could ignore these when we talked about gases.

    Sometimes these attractive forces are the ionic or covalent bonds that were explored previously, but these are not the only types of attractive forces. In this chapter we will introduce additional types of attractive forces. Some attractive forces are much weaker than those we’ve looked at previously. These are called intermolecular forces, and we will look at these in section 9.1. In section 9.2 we will look at some stronger bonds, both reviewing what we saw earlier and introducing some new possibilities.

    Attractive forces are important to understand, because they are the reasons why matter will exist in condensed states such as solids and liquids. Attractive forces are also responsible for solutions forming (and for the substances that form when solutions are mixed together). In section 9.3 we will describe the phase transitions between different physical states. In section 9.4 we will discuss why solutions form based on attractive forces. And in section 9.5 we will revisit double replacement reactions with our new understanding of attractive forces.

    Prior to starting chapter 9 you will want to make sure you are familiar with a few things introduced in previous chapters. The early sections of this chapter will assume you remember some of the concepts related to bonding and molecular polarity that were discussed previously. Section 9.5 builds on the concepts of predicting reactions that we last saw when first introducing chemical reactions. Please review these previous sections if necessary prior to starting this chapter.
