Chapter 1-3 Objectives
Chapter One – Chemical Foundations
1. Students will be able to explain the terms matter, pure substance (element/compound), and mixture (homogeneous/heterogeneous) by giving real-life examples and by drawing examples at the molecular level.
2. Students will be able to differentiate between chemical and physical changes.
3. Students will be able to identify separation techniques as chemical or physical changes.
4. Students will be able to read any laboratory instrument to the proper decimal place and with the appropriate uncertainty.
5. Students will be able to explain the difference between accuracy and precision in terms of scientific instrumentation.
6. Students will be able to convert between units using conversion factors (metric conversions must be memorized).
7. Students will be able to identify the number of significant figures, certain digits, and doubtful digits in an experimental quantities.
8. Students will be able to follow significant figure rules when completing calculations.
Chapter Two – Atoms, Ions, or Molecules
1. Students will be able to describe significant contributions (experiments, theories, ideas, etc.) made in atomic theory history – Democritus, Aristotle, alchemy, Boyle, Stahl, Priestley, Lavosier, Proust, Dalton, Gay-Lussac, Avogadro, Thomson, Millikan, Chadwick, Bequerel, and Rutherford.
2. Students will be able to write nuclear symbols for atoms/ions.
3. Students will be able to determine when atoms/ions are isoelectric.
4. Students will be able to calculate average atomic weights using natural abundances and be able to explain the meaning of a molar mass versus an atomic weight.
5. Students will have a general understanding of the organization of the periodic table (metals/nonmetals/metalloids; groups/periods)
6. Students will be able to name ionic compounds, molecular compounds, and acids. (Note: all polyatomic ions must be memorized and all metal ions with only one charge must be memorized.)
Chapter Three – Stoichiometry
1. Students will be able to explain how a mass spectrometer is able to compare relative masses (special attention to what relative means here).
2. Students will be able to calculate weighted average atomic masses using natural isotopic abundances.
3. Students will be able to convert between atoms/molecules, mass, liters, and moles of any substance. (Molar volume at STP and room conditions should be memorized. Molar masses should be rounded to the hundredths place. Avogadro’s number should be used to 4 significant figures.)
4. Students will be able to differentiate between empirical and molecular formulas by giving examples of each as well as explaining how these terms are used differently for ionic vs. molecular compounds.
5. Students should be able to determine the empirical formula of a compound if given the mass percent, mass composition or mole composition of the compound OR if given experimental data (mass of CO2 and H2O produced).
6. Students should be able to determine the molecular formula of a compound if given the empirical formula as well as the molar mass of the compound.
7. Students will be able to balance chemical equations in terms of moles of reactants and moles of products.
8. Students will be able to complete “three-step mole method” problems. i.e. Students should be able to convert mass/number particles/volume of one substance to a mass/number particles/volume of another substance if given the proper chemical equation.
9. Students should be able to determine the limiting reactant if given amounts of two reactants and amount of product made.
10. If given amount of reactant and amount of product made, students should be able to calculate the percent yield.
Density Lab
1. Students will be able to arrange data to be collected into an organized data table.
2. Students will be able to record data to the appropriate number of significant figures and follow sig fig rules in calculations.
3. Students will be able to record mass data accurately.
4. Students will be able to predict how errors made in lab could affect their calculated result.
Stoichiometry Lab
1. Students will be able to design an experiment in order to determine the correct ratio of reactants between NaClO and Na2S2O3.
2. Students will be able to explain how number of trials (amt of data) affects the reliability of their results.
3. All objectives from Density Lab still hold true.
