1. AP CHEMISTRY unit 1: Chemistry Fundamentals

2. Intro to AP Chemistry September 3 & 4th, 2015 ■Summer Assignment Turn In ■Syllabus ■Check out text books ■Safety Contract ■Test Information ■Calendar ■Start Preassessment /Summer Quiz

3. Syllabus Read through the Syllabus tonight and email me any questions that you have Items of note: ■I recommend purchasing an AP Chemistry review book for you to keep at home ■You will need some form of lab notebook- a bound record of experiments. College admissions officers will sometimes ask to see your lab notebook in order to award credit ■There will be changes that need to occur to the details in the syllabus - I will try to keep you as up to date as possible! But lets all be flexible

4. Safety Contract- signed page due tomorrow ■Read and sign the safety contract ■Have your parents/guardians read and sign the safety contract ■There is also a place on the contract to indicate that you and your family have read the syllabus

11. Friday – September 11, 2015 Problem Set 1 Due Quiz 1 Start Percent Composition / Percent Yield Practice Next Week: Empirical Formulas, Percent Composition, Review Limiting Reactant, Gravimetric Analysis, Quiz 2

12. Friday – September 11, 2015 Today: Review Problem Set #1 Quiz 1 Review Percent Composition & Percent Yield Start Percent Composition / Percent Yield Practice Next Week: Empirical Formulas, Combustion Analysis, Review Limiting Reactant, Gravimetric Analysis, Quiz 2(Friday)

13. Problem Set #1 Review ■Naming Ionic Compounds (Positive Ion + Negative Ion) –Binary: First Element Second Element+ide Example: NaBr Sodium Bromide –Polyatomic: First Element Polyatomic Ion Example: NaOH Sodium Hydroxide –Transition Metal: First Element (Roman Numeral of Charge) Second Element+ide Example: CoCl 3 Cobalt (III) Chloride Example: Fe(OH) 2 Iron (II) Hydroxide

14. Problem Set #1 Review ■Naming Covalent Compounds (non metals) –Prefix+First Element Prefix+Second Element * never use mono for first element Example: CO 2 Carbon dioxide B 2 Br 4 diboron tetrabromide ■Naming Acids -Binary Acids: first word has prefix hydro+ root name of non-metal+ic second word is acid Example: HCl Hydrochloric acid -Acids with Polyatomic Ions: suffix –ate turns to –ic / -ite turns to –ous second word is acid Example: H 2 SO 4 Sulfuric acid Example: H 2 SO 3 Sulfurous acid

15. Problem Set Review ■Average atomic Mass –Average atomic mass is the mass of [each isotope multiplied by its abundance] added together ■Molar Mass –Mass of each element in the compound added together

16. Percent Yield Percent Composition

17. Monday – September 14, 2015 Due Today: Lab – Mass / Mole Percent Composition / Percent Yield Future Due Dates: Problem Set 2: Friday 9/18 Quiz 2: Friday 9/18 Test 1: Monday 9/21 ■Learning Target: –Calculate Molecular and Empirical Formulas AP Standard 1.A.2.b: “Chemical Analysis provides a method for determining the relative number of atoms in a substance which can be used to identify the substance or determine its purity. “

18. Review Law of Definite Proportions ■A compound is always composed of the same elements at fixed proportions by mass Sample Problem: Sodium chloride, NaCl, contains 39% Na (sodium) and 61% Cl (chloride) by mass. If you have a 150-g sample of NaCl, how many grams of sodium and chloride are there in the sample? To check your answer, the sum of the total number of grams of sodium and chloride should be equal to 150 grams. Law of Multiple Proportions ■When two elements combine to form more than one compound, the mass of one element, which combines with a fixed mass of the other element, will always be ratios of whole numbers.
