1. Ammonium chloride NH 4 Cl 2. Aluminum oxide Al 2 O 3 3. Ferric oxide Fe 2 O 3 4. Potassium carbonate 3K 2 (CO) 3 Do Now – count the atoms for each element in the compound. N = 1H = 4Cl = 1 Al = 2O = 3 Fe = 2O = 3 K = 6C = 9O = 9

Homework Achieve 3000 – Choose one of the following “Earth From Above” or “Another Earth” Announcements Chapter 16 Test on Thursday Due Pages 360 (1-8) and 368 (1-8) Homework Finish Carbon Compound Model Packet (summative grade) Review Packet due on Friday (Practice test)

3 Molecules in Living Organisms L.O. SWBAT describe the “BIG 4” organic compounds.

Molecules in Living Organisms exist everywhere can be small or large Common Elements (remember the mod squad) S, C, H, N, O, P

 Organic Compounds relating to, or derived from living matter compounds containing carbon.

Remember valence e- C atoms share 4 e- to achieve an octet (8). C can bond in many ways

Carbon Chain (Challenge) Carbon Chemistry Short Hand Write the chemical formula 1.C 4 H 10 2.C 3 H 7 OH OH

Review Carbon Structures Single Bond Double Bond Triple Bond

Carbon Chains Isomer: Two or more compounds with the same formula but different bonds and different properties.

Carbon Chains Small molecules are called monomers and when joined together they form polymers.

Small Molecules  Support the function of larger molecules. Examples Water (H 2 O) Salt (NaCl) Vitamins Minerals

Macromolecules – giant molecules made from smaller molecules.

The Big 4! Glue in!  Carbohydrates Made up of C, H, O Sugar and Starch Provide Energy Example: Glucose– C 6 H 12 O 6

 Lipids Made up of C, H, O Saturated Unsaturated Fats, oils, waxes, cholesterol

 Proteins Made up of C, O, H, N, S composed of amino acids Hemoglobin in our blood.

DNA Made up of C, O, H, N, P Chain of billions of small molecules Double helix structure A-T (Adenine-Thymine) G-C (Guanine – Cytosine)

Thumbs up Thumbs down Are the following molecules large or small? DNA – Large Water – Small (H 2 0) Carbohydrates – Large Salt – Small (NaCl)

Pair Share MoCl 2 – No ….. Mo and Cl are not essential elements to life. C 3 H 7 NO 2 S – Yes …. C H O N S are all essential elements to life. CsI – No Cs and I are not essential elements to life. Are the following molecules most likely to be found in living organisms? Why? Example: C 27 H 46 O Yes, C H O are all essential elements to life.

Summary 1.Today I learned about… 2.What are the Big 4 organic compounds? 3. Why are carbon compounds so important to understand? 4.What are some of the different molecules that are found in living organisms? 5.What elements are repeatedly found in the molecules?
