1. The Great Peanut Race

2. The Great Peanut Race 2 Beakers (A & B)
Each beaker has ~ 150 mL of liquid
How many packing peanuts can each beaker hold?

3. The Great Peanut Race Explanation Water – polar covalent
Acetone – non-polar covalent
Packing peanuts – non-polar covalent

4. LIKE DISSOLVES LIKE Polar molecules dissolve polar molecules
Water & methanol
Non-polar molecules dissolve non-polar molecules
Acetone & packing peanuts
Oil & kerosene

5. Real World Applications
Cleaning Clothes
Polar stains can be dissolved with a polar solvent (cleaner)
Non-polar stains can be dissolved with a non-polar solvent (cleaner)
Cleaning Dishes & Oil Spills
Grease/oil is non-polar and soap has a non-polar hydrophobic tail
micelle
