(A) Methane (B) Ethane (C) Butane (D) All the gases will condense at the same pressure.

10. Section II o oFree Response o o105 minutes o o50% of the exam grade o o“2 major parts” o oGiven information: 1. 1. Periodic Table 2. 2. Equation Sheet 3. 3. Reduction Potential Table

11. 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.

12. Section II o oQuestions #1-3 1. 1. Quantitative section 2. 2. CAN USE a calculator 3. 3. Each question is worth 10 points o oQuestions #4-7 1. 1. Short Essays/Problems 2. 2. Each question is worth 4 points 3. 3. CAN USE a calculator

13. 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

24. 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)

25. 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.

26. 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.

27. 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)
