Unit 4 Theme – The Madness of Fritz Haber
Question of the Day How many drops of water can you fit on a penny?
Justify – TPS Why do so many drops of water fit on a penny?
Lecture 4.1 – Intermolecular Forces and the Dissolving Process
Today’s Learning Targets LT 4.1 – I can discuss how ionic solids dissolve due to the random molecular motion of the water molecules. LT 4.2 – I can identify a compound as containing hydrogen bonding, dipole – dipole forces, and Van der Waals forces. LT 4.3 – I can compare and contrast various intermolecular forces and relate them to the dissolving process of a solid.
What do solids, liquids, and gases look like?
I. Solids Atoms in a solid hold a very fixed position. They are said to be vibrating in place.
II. Liquids Atoms in a liquid are further spread out from one another. They flow freely within the solution and are moving in a random motion.
III. Gases Atoms in a gas are in constant random motion.
