Journal Entry:

What (aq) mean in a chemical reaction? What would substance labeled with aq look like if you saw it?

Learning Intentions

• You will review practice problems to calculate the limiting reactant, as well as the theoretical and percent yields for a chemical reaction.

• You will learn about hydrogen bonding found in water and be able to represent molecules with hydrogen bonding through diagrams that indicate location of hydrogen bonding.

• You will learn how hydrogen bonding gives rise to the unique properties of water.

• You will learn how ionic interactions with dipoles are important in the solubility of ionic compounds in polar solvents.

Closing Task:

Content Standards being covered:

Dipole forces result from the attraction among the positive end and negative ends of polar molecular. Hydrogen bonding is a strong type of dipole-dipole force that exists when very electronegative atoms (N, O, and F) are involved. (EK 2.B.2)

The solubility of a substance can be understood in terms of chemical equilibrium (EK 6.C.3)
