THE EXAM!   Monday, May 2,2016 8:00 am   WE have 245 Days to Get Ready for a 3,4 or 5

WHAT I NEED TO KNOW ABOUT THE EXAM! WWhat is the exam format? HHow is it graded? WWhen will I know how I did? HHow well does everybody score?

What is the exam format?   Two major sections   Section I is multiple choice (90 minutes)   Section II is free response (105 minutes)

Section I 60 Multiple Choice Questions covering all topics (only 50 will be part of your score) 50% of the exam grade 4 choices (letters a-d) per question Periodic Table and Equation Sheet NO calculator 90 minutes for this part

Section I Grading  Score is based on number correct  And ONLY number correct!  NO PENALTY FOR GUESSING!

MULTIPLE CHOICE Example #1 Which element forms an oxide that is a molecular solid?molecular solid a)sodium b)argon c)carbon d)silver

MULTIPLE CHOICE Example #2 Which of the following particulate diagrams best shows the formation of water vapor from hydrogen gas and oxygen gas in a rigid container at 125°C?

MULTIPLE CHOICE Examples #’s 3-5 Questions 3–5 refer to three gases in identical rigid containers under the conditions given in the table below.

MULTIPLE CHOICE Examples #’s The average kinetic energy of the gas molecules is (A) greatest in container A (B) greatest in container B (C) greatest in container C (D) the same in all three containers 4. The density of the gas, in g/L, is (A) greatest in container A (B) greatest in container B (C) greatest in container C (D) the same in all three containers 5. If the pressure of each gas is increased at constant temperature until condensation occurs, which gas will condense at the lowest pressure? (A) Methane (B) Ethane (C) Butane (D) All the gases will condense at the same pressure.

Section II o oFree Response o o105 minutes o o50% of the exam grade o o“2 major parts” o oGiven information: Periodic Table Equation Sheet Reduction Potential Table

Section II Grading   Quantitative Problems & Essays with various point values   Grading protocol (rubric) established & partial points awarded for each part.   “Conditional grading” is in effect.

Section II o oQuestions # Quantitative section CAN USE a calculator Each question is worth 10 points o oQuestions # Short Essays/Problems Each question is worth 4 points CAN USE a calculator

Section II o oProblems 1-3   Topics vary, examples are Equilibrium Stoichiometry Kinetics Gas laws Thermodynamics Electrochemistry   Conditional Grading in effect   Sig Figs “Count” on 1 problem

Example of Q’s Free Response Example Problem

Section II o oProblems 4-7   Problems are “essays” Get to the point by using key terms   Must do both all of them   Topics vary, examples are Structure and Properties of Matter Chemical Reactions and Rates Thermodynamics Lab Procedures Equilibrium

Example of Q’s B Free Response Example Problem #6 Example Test #3

Example of Q’s 4-7

Who grades the exams? (AP Chemistry Reading)   Chief Reader   Question Leader   Table Leader (2-4/Q)   Reader (8-10/TL)   (Aids)

When are the exams graded? Dates: 7 Days in early-June Venue: Salt Lake City, UT Readers: 300+ College and High school teachers are readers. They must teach AP Chemistry or equivalent courses in their institutions

When will I know how I did? You and I will get your results in early July You and I will get your results in early July

AP SCORE COMPARISON AP SCORE COMPARISON Year Mr. Morrow ’s 2015 Mr. Morrow's Average AP Score Mean # of students 122,651132,777125,856149, , % of my students score a 3 or higher

Equation Section   Equation writing   Three statements   For each you must write a balanced equation (1 point for reactants and 2 points for products; 1 point for balancing)   There is a follow up questions for each equation (1 point)

Equation Section Directions o oProvide a balanced chemical equation o oEquations should only show the reacting substances o oAnd then an additional question will be asked about the equation/reaction o oThe majority of the credit for a response will be earned for writing the balanced equation oThe oThe remaining credit will be earned for correctly answering the question that follows each reaction, which will require the student to focus more on the meaning of the reaction.

Equation Section o oA solution of nickel (II) bromide is added to a solution of potassium hydroxide. oIdentify oIdentify the spectator ions in the reaction mixture.

Equation Section oA oA solution of acetic (ethanoic) acid is added to solid calcium carbonate. o oWhat visual evidence would be seen that indicates a chemical reaction has occurred? o o(If (If hydrochloric acid replaces acetic acid will the reaction occur slower or faster. Explain)
