Unit 1 · 16 skills

Thermochemistry

Designing experiments and gathering evidence

Reasoning and working as a team

Energy in chemical reactions

The official wording · 16 outcomes
1.1
design an experiment identifying and controlling major variables

1.6
apply and assess methods of predicting heats of reaction
1.7
propose alternative solutions to a given practical problem, identify the potential strengths and weaknesses of each
1.8

1.9

1.10
write and balance chemical equations for combustion reactions of alkanes
1.11
define endothermic reaction, exothermic reaction, specific heat, enthalpy
1.12
calculate and compare the energy involved in changes of state and that in chemical reactions
1.13
calculate the changes in energy of various chemical reactions using bond energy, heats of formation and Hess
1.14
illustrate changes in energy of various chemical reactions, using potential energy diagrams
1.15
determine experimentally the changes in energy of various chemical reactions
1.16
compare the molar enthalpies of several combustion reactions involving organic compounds

Key ideas

  1. Identify the independent variable (e.g. amount of reactant), dependent (temperature change), and controls.

  2. Hess's law: the total enthalpy change is the sum of steps, regardless of path.

  3. Complete combustion of a hydrocarbon gives carbon dioxide and water.

  4. Control heat loss, mass of water, and starting temperature.

  5. Heats of reaction can be predicted from bond energies or standard heats of formation.

Watch out for

  • Changing several variables at once.
  • Adding enthalpies without accounting for reaction direction.
  • Forgetting water as a product.

Unit 2 · 8 skills

From Solutions to Kinetics to Equilibrium

Solutions, kinetics, and equilibrium

The official wording · 8 outcomes
2.1
develop appropriate sampling procedures
2.2
implement appropriate sampling procedures
2.3
compile and organize data, using appropriate formats and data treatments to facilitate interpretation of the data
2.4
describe and apply classification systems and nomenclatures used in the sciences
2.5
identify and discuss the properties and situations in which the rate of reaction is a factor
2.6
define the concept of equilibrium as it pertains to solutions
2.7
explain solubility, using the concept of equilibrium
2.8
explain how different factors affect solubility, using the concept of equilibrium

Key ideas

  1. Sampling means selecting representative measurements over time.

  2. For rates, sample at regular time intervals.

  3. Enough samples capture the trend without bias.

  4. A good sampling plan makes the data representative.

  5. Carry out the planned sampling consistently.

Watch out for

  • Sampling too infrequently to see the trend.
  • Biased sampling.
  • Irregular sampling intervals.

Unit 3 · 17 skills

Acids and Bases

Prediction and safe technique

3.3
select and use apparatus and material safely
3.4

3.7
interpret patterns and trends in data, and infer or calculate linear and non-linear relationships among variables
3.8
identify new questions or problems that arise from what was learned
3.9
select and use appropriate numeric, symbolic, graphical, and linguistic modes of representation
3.10
work co-operatively with team
3.11
describe various acid-base definitions up to the Brønsted-Lowry definition
3.12
predict products of acid- base reactions
3.13
compare strong and weak acids and bases using the concept of equilibrium
3.14
calculate the pH of an acid or a base given its concentration, and vice ve
3.15
describe the interactions between H+ ions and OH- ions using Le Châtelier
3.16
determine the concentration of an acid or base solution using stoichiometry
3.17
explain how acid-base indicators function

Key ideas

  1. A hypothesis proposes a testable acid-base relationship.

  2. A line of best fit summarizes the trend in scattered data.

  3. Arrhenius: acids produce H+ and bases produce OH- in water.

  4. A prediction states the expected measurement (e.g. the titration volume).

  5. Interpolation reads a value within the data range; extrapolation beyond it.

Watch out for

  • Making a prediction with no basis.
  • Forcing a line through every point.
  • Thinking acids and bases only exist in water.

Unit 4 · 14 skills

Organic Chemistry

Investigating organic chemistry

Organic compounds

The official wording · 14 outcomes
4.1
define and delimit problems to facilitate investigation
4.2
identify limitations of a given classification system and identify alternative ways of classifying
4.3
identify and apply criteria, including the presence of bias, for evaluating

4.12
classify various organic compounds by determining to which families they belong
4.13
write and balance chemical equations to predict the reactions of selected organic compounds
4.14
describe processes of polymerization and identify some important natural and synthetic polymers

Key ideas

  1. Delimiting a problem narrows it to a specific, answerable question.

  2. Organic compounds are represented by molecular, structural, and condensed formulas.

  3. A well-defined problem states the variables and scope.

  4. A structural formula shows how the atoms are connected.

  5. Broad problems must be broken into manageable parts.

Watch out for

  • Leaving a problem too broad to investigate.
  • Confusing molecular and structural formulas.
  • Not stating the variables.
