Exam #1  covers the material in Chapters 1 & 2, all ALE's for Chapters 1 & 2 (i.e. ALE's 1 - 9), and labs 1- 3 Scroll down this page for a links to a practice exam (short answer questions), Multiple Choice Practice Questions, dimensional analysis practice, matter and measurement practice and inorganic nomenclature practice for exam 1. 

Bring the following with you to the exam:

Exam #1 consists of two parts:

  • Part 1 (~30 points).  ~10 multiple choice questions

  • Part 2 (~70 points).  ~10 questions involving the analysis of data, calculations and chemical nomenclature.

Stuff to concentrate on while reviewing:

  1. Terms/Concepts
    1. Density
    2. Precision, accuracy
    3. Scientific method
    4. Matter, substance, mixture, homogeneous, heterogeneous
    5. Physical and chemical properties, and changes
    6. Element, atom, compound, molecule, isotope
    7. Atomic number, atomic mass
    8. Proton, neutron, electron
  2. Skills/Background Knowledge
    1. Metric units of grams, meters, liters, oC, K
    2. Metric prefixes mega, kilo, centi, milli, micro, nano
    3. Significant figures, rounding off
    4. Scientific notation
    5. Symbols and Names of the common elements and ions
  3. Problem solving abilities
    1. Metric conversions

    3. Percent error
    4. Molecular mass
    5. Percent composition
    6. Average atomic mass
  4. Naming & writing formulas. Click here for a list of the common symbols and ions that you should know

Specific concepts and skills to concentrate on when studying

  • Understand these Concepts. Chapter 1: 1-8 on page 32. Chapter 2: 1-3, 4 (only Rutherford's gold foil experiment), 5-8 on page 77

  • Master These Skills. Chapter 1:  1-4 on page 32.  Chapter 2: 1-7 on page 77.

  • All ALE's for Chapters 1 & 2 (i.e. ALE's 1-9)

  • Labs 1-3, especially how to do all calculations, error analysis questions, how to calculate % error, the use of standard deviation to measure precision, the graphing of data and interpreting graphs. Be able to the % water in a hydrate from experimental data and from the formula of a hydrate.

  • Letter from Dalton activity (not used this quarter)

  •  Significant Figures Tutorial and Practice Problems; Chemical Nomenclature Flowchart;  Naming Compounds Handout and Practice Problems
