General Chemistry Course Outline and Key Topics (Grade 11, SCH 3U)

Course Overview

Introduction to General Chemistry

This course provides a comprehensive introduction to chemistry, focusing on the properties of chemicals, chemical bonds, reactions, quantitative relationships, solutions, solubility, and atmospheric chemistry. Students will develop analytical skills and explore the impact of chemical reactions on society and the environment.

• Scientific Investigation Skills: Emphasis on inquiry, research, planning, recording, analysis, interpretation, and communication.

• Career Exploration: Identification of chemistry-related careers and contributions of scientists.

Matter, Chemical Trends, and Chemical Bonding

Atoms & Elements

This unit explores the fundamental properties of elements and their organization in the periodic table, as well as the nature of chemical bonds.

• Atomic Number & Mass Number: Atomic number is the number of protons in an atom; mass number is the sum of protons and neutrons.

• Isotopes & Radioisotopes: Isotopes are atoms of the same element with different numbers of neutrons; radioisotopes are isotopes with unstable nuclei.

• Isotopic Abundance & Relative Atomic Mass: The average mass of an element's isotopes, weighted by their abundance.

• Periodic Law & Trends: Elements are arranged by increasing atomic number; trends include electronegativity, atomic radius, and ionization energy.

• Lewis Diagrams: Visual representations of valence electrons.

• Ionic and Covalent Bond Formation: Ionic bonds form between metals and nonmetals; covalent bonds form between nonmetals.

• Physical Properties of Compounds: Comparison of ionic and molecular compounds.

• Formulae and Nomenclature: Rules for naming and writing chemical formulas.

Example: Sodium (Na) forms an ionic bond with chlorine (Cl) to produce sodium chloride (NaCl).

Chemical Reactions

Types and Properties of Chemical Reactions

This unit covers the identification, classification, and balancing of chemical reactions, as well as their societal and environmental impacts.

• Balancing Chemical Equations: Ensures conservation of mass; each element has the same number of atoms on both sides of the equation.

• Types of Reactions: Includes synthesis, decomposition, single displacement, double displacement, combustion, and acid-base reactions.

• Predicting Products: Using reactant properties and reaction types to determine products.

• Combustion: Complete combustion produces CO2 and H2O; incomplete combustion produces CO and/or C.

• Acid and Base Formation: Reactions that produce acids or bases.

Example: $\mathrm{CH_4 + 2O_2 \rightarrow CO_2 + 2H_2O}$ (complete combustion of methane)

Quantities in Chemical Reactions

The Mole Concept and Quantitative Relationships

This unit focuses on quantitative analysis in chemical reactions, including the mole concept, stoichiometry, and limiting reagents.

• Law of Definite Proportions: Elements combine in fixed ratios to form compounds.

• Avogadro’s Number: $6.022 \times 10^{23}$ particles per mole.

• Mole Concept: The mole is a unit for counting particles in chemistry.

• Molar Mass: Mass of one mole of a substance (g/mol).

• Percentage Composition: The percent by mass of each element in a compound.

• Empirical and Molecular Formula: Empirical formula shows simplest ratio; molecular formula shows actual number of atoms.

• Stoichiometry: Quantitative relationships in balanced equations.

• Limiting Reagents: The reactant that determines the maximum amount of product.

Example: $\mathrm{n = \frac{m}{M}}$ (number of moles = mass / molar mass)

Solutions and Solubility

Properties and Quantitative Analysis of Solutions

This unit examines the formation, properties, and concentration of solutions, as well as water quality and titration.

• Properties of Water: Water is a universal solvent due to its polarity.

• Solution Formation: Dissolving process depends on solute-solvent interactions.

• Factors Affecting Solubility: Temperature, pressure, and nature of solute/solvent.

• Precipitate Formation: Insoluble products formed in double displacement reactions.

• Ionic Equations: Show ions involved in reactions.

• Arrhenius Theory: Acids produce H+ ions; bases produce OH- ions in solution.

• Degree of Ionization: Extent to which a substance ionizes in water.

• Solution Concentration: Expressed as molarity ($\mathrm{M = \frac{n}{V}}$).

• Titration: Technique to determine concentration of a solution.

Example: $\mathrm{C = \frac{n}{V}}$ (concentration = moles / volume)

Gases and Atmospheric Chemistry

Gas Laws and Environmental Impact

This unit explores the properties of gases, gas laws, and the impact of human activities on air quality.

• Chemical Components of Earth's Atmosphere: Nitrogen, oxygen, argon, carbon dioxide, and trace gases.

• Kinetic Molecular Theory: Explains gas behavior based on particle motion.

• Gas Laws:

  • Boyle’s Law: $\mathrm{P_1V_1 = P_2V_2}$ (pressure and volume inversely related)

  • Charles’s Law: $\mathrm{\frac{V_1}{T_1} = \frac{V_2}{T_2}}$ (volume and temperature directly related)

  • Gay-Lussac’s Law: $\mathrm{\frac{P_1}{T_1} = \frac{P_2}{T_2}}$ (pressure and temperature directly related)

  • Combined Gas Law: $\mathrm{\frac{P_1V_1}{T_1} = \frac{P_2V_2}{T_2}}$

  • Ideal Gas Law: $\mathrm{PV = nRT}$

  • Dalton’s Law of Partial Pressures: $\mathrm{P_{total} = P_1 + P_2 + ...}$

• Avogadro’s Hypothesis: Equal volumes of gases at same temperature and pressure contain equal numbers of particles.

• Molar Volume: Volume occupied by one mole of gas at STP (22.4 L).

• Air Quality: Effects of technology and human activity; initiatives to reduce pollution.

Example: $\mathrm{PV = nRT}$ (ideal gas law)

Assessment and Evaluation

Methods and Categories

Assessment is based on provincial curriculum expectations and achievement levels. Strategies include feedback, goal setting, evaluation, and reporting. Major evaluations may include assignments, debates, exams, laboratory investigations, presentations, projects, quizzes, reports, and tests.

• Term Evaluation: Application/Making Connections (25%), Communication (25%), Knowledge/Understanding (25%), Thinking/Inquiry (25%)

• Final Evaluation: Culminating Activity (10%), Exam (20%)

Learning Skills and Academic Integrity

Work Habits and Responsibilities

Learning skills such as responsibility, organization, independent work, collaboration, initiative, and self-regulation are assessed and reported. Academic honesty is required; plagiarism and cheating result in consequences. Students must manage assignments and deadlines responsibly.
