2 Examination Outline & Review Chemistry, Grade 11 Academic Examination Date: Exam Duration: Equipment Required: Exam format: Wednesday, June 20, 9:00 a.m. 1.5 Hours pencils, pens, eraser, liquid paper, calculator Part A: Multiple Choice (~35 marks, ~ 40 minutes) Part B: Short Answer/Calculations (~ 40 marks ~ 45 minutes) Chapter/Sections Chapter (inclusive) Topics & Sections to Review in preparation for exam Topics Limiting Reagents and Reagents in Excess (definitions) Writing & Balancing chemical equations Types of Nuclear Reactions/Balancing Nuclear Reactions: REMEMBER: Nuclear particles/rays (alpha, beta, gamma) Stoichiometry Problems involving masses apply the 4-step process. REMEMBER n = m/m Calculating Limiting and Excess Reagents REMEMBER: A) If information is given on only ONE of the reagents, assume this is the limiting reagent B) If information is given on all the reagents, you must first decide which reagent is in excess and which is the limiting reagent; you always use the limiting reagent, since it determines the amount of product formed! + Calculating the Percent Yield of a Chemical Reaction Chapter 6 6.2, 6.3, 6.5, ( *6.4) Chapter 7 7.1, 7.3, 7.5, 7.6 (*7.4) Using Intermolecular forces to explain solutions Determining Molar Concentration (C = n/v) & % concentration Preparing STANDARD solutions Preparing Solutions by dilution: REMEMBER C i V i = C 2 V 2 * General knowledge about water contaminants Factors that affect the solubility of solids, gases, liquids The solubility Chart for Ionic Compounds Writing Net Ionic Equations Writing Flow charts to show Sequential Qualitative Chemical Analysis Stoichiometry Problems involving Solutions General knowledge about waste water treatment
