Date: 9/28-29/11HW: 2.9 CTG, pg. 168 #1-8 • LO: • Define organic as it applies to chemistry • Write and balance equations for combustion reactions • SC • Combust a material present in fruit rinds • Represent the combustion of hydrocarbons as a chemical equations • Learn the formulas and proper names for simple hydrocarbons • Make 2-dimentional drawings showing the chemical bonding structure in simple hydrocarbons • Classify materials as organic or inorganic • Explore various definitions of the term “organic” • Do Now: • 2.8 Quiz • Copy LO and SC on new left side page • WDYS/WDYT pg. 162 • Agenda • Do Now • Investigate • Summary
Investigate • Demo #1-3 • #4-6 as a class
Chem Talk-Read pg. 164-66 • What caused the flames with the fruit? • What does organic mean? • Ethylene (C2H4) gas, responsible for ripening the fruit • A molecular compound of carbon
Chem Talk • What is inorganic? • Where do you find organic compounds? • The opposite of organic. A compound not based on carbon • Everywhere! Largest area of chemistry • Plants, animals, gasoline, sugar, medicines, etc
Chem Talk • What is the difference between “organic” in chemistry and “organic” in food? • Organic food simply refers to totally natural, with no man-made interference.
Chem Talk • What are hydrocarbons? • What is combustion? • Composed of only carbon and hydrogen • Fuel, gas, kerosene, candle wax, propane, natural gas • Burning of hydrocarbons • Combined with oxygen • Generates heat and carbon dioxide
Chem Talk • What does combustion look like in a chemical equation? • This equation isn’t balanced! • Remember conservation of mass tells us what we start with we must end with!
Summary • Checking Up Questions-pg. 166 #1-3 • Essential Questions-pg. 167 • How do you know? • Why do you believe? • Why should you care? • LO and SC reflections
