  7. 7. Chemical Properties <ul><li>PEANUT BUTTER </li></ul><ul><li>Delicious </li></ul><ul><li>Goes well with toasted, raisin swirl bread </li></ul><ul><li>Gets stale and old if left open on the counter </li></ul><ul><li>Many of the chemical properties of Peanut Butter are unknown at this time </li></ul><ul><li>Probably because no one cares enough </li></ul><ul><li>LEAD </li></ul><ul><li>Rarely found pure in nature </li></ul><ul><li>Usually combines with zinc, copper and silver </li></ul><ul><li>Becomes covered in an oxide film when exposed to moist air </li></ul><ul><li>Reacts vigorously with fluorine (F) at room temperature </li></ul><ul><li>Reacts well with chlorine (Cl) when warmed </li></ul>Yes, this is a molecule of peanut butter. … I don’t care if it’s made entirely of lead! … IT’S PEANUT BUTTER!
  8. 8. Uses of the Element <ul><li>LEAD </li></ul><ul><li>Lead Oxide (PbO) is created when lead makes contact with the air, making this element useful in containing sulphuric acid </li></ul><ul><li>Used extensively in car batteries, projectiles, electrodes in the process of electrolysis, glass for computer and television screens, sound absorber </li></ul><ul><li>Other compounds used in paint, insecticides, storage batteries </li></ul><ul><li>Alloys are used in solder, pewter, bullets, antifriction lubricants, plumbing </li></ul><ul><li>PEANUT BUTTER </li></ul><ul><li>When placed with jelly on a sandwich, it tastes good </li></ul><ul><li>When eaten directly, it leaves a foul aftertaste </li></ul><ul><li>COOKIES! </li></ul><ul><li>Especially used in making fun of lead, because their abbreviations are so close </li></ul><ul><li>What a coincidence </li></ul><ul><li>Who would’ve thought? </li></ul><ul><li>Oh, wait, me. </li></ul>
  9. 9. Common Compounds <ul><li>PbO- Lead Oxide- insoluble to sulphuric acid </li></ul><ul><li>PbF(2)- Lead Fluoride- poisonous </li></ul><ul><li>PbCl(2)- Lead Chloride- poisonous </li></ul><ul><li>2 fluorides, 2 chlorides, 2 bromides, 1 iodide, 1 hydride, 4 oxides, 1 sulfide, 1 selenide, 1 telluride </li></ul><ul><li>PbJ- Peanut Butter ‘n’ Jelly Sandwich- used in elementary school lunches </li></ul><ul><li>PbB- Peanut Butter ‘n’ Bananas- used in elementary school lunches </li></ul><ul><li>PbP- Peanut Butter Pancakes- used in Mrs. Mizak’s kitchen </li></ul><ul><li>PbC- Peanut Butter ‘n’ Crackers- delicious after school snack </li></ul>
  10. 10. Interesting Bits of Information <ul><li>Lead had been mentioned in the Book of Exodus </li></ul><ul><li>Alchemists attributed lead to the planet Saturn, as being the oldest element on earth </li></ul><ul><li>Lead can be purified from galena, which can be mined in Australia, which mines 19% of the world’s galena, which is cool because they have kangaroos </li></ul><ul><li>Lead is one of four metals that have extremely damaging effects on the human body </li></ul><ul><li>Lead is pyrophoric when divided into a fine powder, making it a fire hazard </li></ul><ul><li>Peanut butter has 190 calories </li></ul><ul><li>17 grams of fat </li></ul><ul><li>NO CHOLESTEROL! </li></ul><ul><li>160mg of sodium (Peaches, go have a party) </li></ul><ul><li>7g of carbohydrates </li></ul><ul><li>6g of protein </li></ul><ul><li>2% calcium (Kristina, you may have a party as well) </li></ul><ul><li>4% iron (I don’t know who’s doing iron, but y’all should have a party together. That’d be GROOVY) </li></ul>
