Working Like a Chemist

How Atomic Theory Evolved

  • Evidence, theories, and the evolving atomic model

    I can explain how evidence and paradigms drove the evolution of atomic theory.

Working Safely and Measuring Well

  • Safe laboratory protocols and WHMIS

    I can work safely in the chemistry lab and interpret WHMIS labels.

  • Collecting and analysing data

    I can choose and apply appropriate techniques and technologies to collect and analyse chemistry data.

  • Measurement uncertainty and significant figures

    I can express and use measurement uncertainty and report data with correct significant figures.

Argument, Design, and Decisions

  • Evaluating phenomena with argumentation

    I can build a scientific argument using claim, evidence, and reasoning.

  • Designing a controlled experiment

    I can design an experiment that identifies and controls its major variables.

  • Communicating plans, data, and results

    I can communicate my chemistry plans, data, and results clearly and conventionally.

  • Risks and benefits of applying chemistry

    I can analyse from multiple perspectives the risks and benefits of applying chemical knowledge.

The official wording · 8 outcomes
1.1
the role of evidence, theories, and paradigms in the development of scientific knowledge and how it evolves as new evidence comes to light
1.2
apply knowledge and understanding of safe laboratory protocols and procedures
1.3
apply appropriate techniques, procedures, and technologies for collecting and analysing data to solve problems
1.4
use uncertainty in data measurement and data processing
1.5

1.6

1.7

1.8

Key ideas

  1. Scientific theories are tested against evidence and revised, restricted, or replaced when they no longer fit.

  2. WHMIS 2015 pictograms and labels warn of the hazards of a chemical and how to handle it.

  3. A scientific argument links a claim to evidence through reasoning.

  4. The atomic model evolved through Dalton, Thomson, Rutherford, Bohr, and the quantum mechanical model.

  5. General safety guidelines apply to every activity; specific hazards apply to particular experiments.

Watch out for

  • Thinking older atomic models were simply 'wrong' - each was the best fit for the evidence of its time.
  • Thinking safety rules only apply to 'dangerous-looking' chemicals - every activity has protocols.
  • Thinking a claim alone is an argument - it needs evidence and reasoning.

Stoichiometry

The Mole and Mole Conversions

  • The mole, molar mass, and conversions

    I can convert among mass, moles, particles, and gas volume using molar mass and Avogadro's number.

  • Percent composition and empirical/molecular formulas

    I can find percent composition and empirical and molecular formulas, including for hydrates.

Reaction Stoichiometry

  • Mole ratios and stoichiometric calculations

    I can use mole ratios and dimensional analysis to solve reaction stoichiometry problems.

  • Predicting single-replacement and precipitate reactions

    I can predict whether single-replacement and double-displacement reactions will proceed.

Limiting Reagent and Percentage Yield

The official wording · 6 outcomes
2.1
perform mole-mass-particle-volume calculations for pure substances
2.2
perform mole-mass-particle-volume calculations for pure substances
2.3
analyse chemical reactions to solve problems requiring stoichiometry
2.4
analyse chemical reactions
2.5
determine the percentage yield of a chemical process
2.6
determine the percentage yield of a chemical process

Key ideas

  1. A mole is 6.02 x 10^23 particles (Avogadro's number); molar mass is the mass in grams of one mole.

  2. The coefficients in a balanced equation give the mole ratio of reactants and products.

  3. The limiting reagent is the reactant that runs out first and caps how much product forms.

  4. Average atomic mass is the weighted mean of an element's isotope masses by their abundance.

  5. The Law of Conservation of Mass means atoms and mass are conserved in a balanced equation.

Watch out for

  • Thinking a mole is a mass - it is a count of particles.
  • Using the mass ratio instead of the mole ratio from the coefficients.
  • Thinking the reactant present in smaller mass is always the limiting one - compare moles by the ratio.

Unit 3 · 8 skills

Structure, Bonding, and Properties

Bonding, VSEPR, and Polarity

Intermolecular Forces and Properties

  • Types of intermolecular forces

    I can identify and compare the strength of the intermolecular forces between molecules.

  • Physical properties of ionic, molecular, and metallic substances

    I can compare the physical properties of ionic, molecular, and metallic substances.

Solubility Equilibrium

  • Solubility as a dynamic equilibrium

    I can describe solubility equilibrium and explain what changes solubility.

  • Solubility curves and precipitate prediction

    I can use solubility curves and generalizations to calculate solubility and predict precipitates.

3.6

3.7

3.8
apply the concept of solubility equilibrium in calculations and generalizations

Key ideas

  1. Bonding is a continuum: nonpolar covalent to polar covalent to ionic, set by electronegativity difference.

  2. Van der Waals forces include London dispersion, dipole-dipole, and hydrogen bonding, in increasing strength.

  3. In a saturated solution the rate of dissolving equals the rate of crystallizing - a dynamic equilibrium.

  4. Ionic bonds transfer electrons (metal + non-metal); covalent bonds share them; metallic bonds pool valence electrons.

  5. London dispersion forces exist between all molecules; dipole-dipole forces act between polar molecules.

Watch out for

  • Thinking bonds are strictly ionic OR covalent - most fall along a continuum.
  • Thinking covalent bonds break when a molecular substance boils - the intermolecular forces break.
  • Thinking a saturated solution is inactive - dissolving and crystallizing continue at equal rates.

Organic Chemistry

Naming and Classifying Organic Compounds

Structural Formulas, Isomers, and Reactions

4.5

4.6

Key ideas

  1. Carbon forms four covalent bonds and can bond to itself in chains, branches, and rings.

  2. A structural formula shows how atoms are connected in a molecule.

  3. Carbon can form single, double, and triple bonds, adding to structural variety.

  4. Condensed and line-structural formulas are shorthand for the full structural formula.

  5. Carbon-carbon bonds are strong, giving organic compounds relatively low reactivity and many stable structures.

Watch out for

  • Thinking carbon forms only single bonds - it also forms double and triple bonds.
  • Thinking a molecular formula is the same as a structural formula - the structural formula shows connections.
  • Thinking 'organic' means 'living' - it means carbon-based compounds.
