Discover the properties and uses of palladium, a metal that can be pounded into thin sheets and is crucial in catalytic converters. Learn how solid palladium can absorb hydrogen in its crystal lattice structure. This lesson will cover classifying reactions, with practice notes and homework assignments on pages 27-30. Don't miss out on celebrating Traditions Day tomorrow!

Warm up 12/19/13 • Question: How many molecules are in a mole of water? • Answer: • 6.02 x1023 molecules. • Goal: I will learn to classify reactions.
ELEMENT OF THE DAY • 46 – Palladium – Pd • Palladium, like gold, can be pounded into thin sheets less than 1,000 atoms thick. • Palladium is also used in catalytic converters, which turn unburned fuel into CO2 and water, making exhaust much cleaner. • Solid palladium metal can actually absorb hydrogen. The crystal lattice of palladium atoms leaves enough space for hydrogen atoms to get into the empty spaces.
