 Handout: CHE 111 General Chemistry for NCE One Students

Course Overview 

This course introduces foundational principles of chemistry, emphasizing conceptual understanding, problem-solving skills, and practical applications. Designed for future teachers, it equips students with the knowledge and pedagogical tools to effectively teach chemistry at the secondary level.  

Key Topics 

1. Introduction to Chemistry 

   - Matter, physical/chemical properties, and classification (elements, compounds, mixtures).  

   - Scientific method, measurement units (SI), and lab safety protocols.  

2. Atomic Structure  

   - Subatomic particles (protons, neutrons, electrons), atomic number, mass number.  

   - Atomic models (Dalton, Rutherford, Bohr), isotopes, and electron configurations.  

3. Periodic Table  

   - Organization (periods, groups), trends (atomic radius, electronegativity, ionization energy).  

   - Predicting chemical behavior (metals, nonmetals, metalloids).  

4. Chemical Bonding 

   - Ionic, covalent, and metallic bonds; Lewis structures; VSEPR theory.  

   - Intermolecular forces (hydrogen bonding, van der Waals).  

5. Stoichiometry 

   - Mole concept, balancing equations, limiting reactants, percent yield.  

6. States of Matter

   - Properties of gases, liquids, solids; phase changes; gas laws (Boyle, Charles, Avogadro).  

7. Thermochemistry  

   - Energy changes (ΔH), calorimetry, Hess’s Law, enthalpy diagrams.  

8. Acids and Bases  

   - pH scale, titration, buffer solutions, Brønsted-Lowry theory.  

Learning Objectives  

By the end of this course, students will be able to:  

1. Explain atomic structure and periodic trends.  

2. Predict bonding types using Lewis/VSEPR theories.  

3. Perform stoichiometric calculations (moles, mass, volume).  

4. Analyze gas behavior using kinetic molecular theory.  

5. Apply thermochemical principles to energy changes.  

6. Conduct acid-base titrations and interpret pH data.  

Recommended Study Tips  

- Regular Practice: Solve numerical problems daily (e.g., stoichiometry, gas laws).  

- Concept Maps: Visualize relationships (e.g., periodic trends, bonding).  

- Group Study: Discuss topics with peers to deepen understanding and practice teaching.  

- Labs: Engage actively in experiments to connect theory with practice.  

- Seek Help: Clarify doubts early with instructors or online resources (e.g., Khan Academy).  

Assessment Methods  

- Exams (60%): Theory and calculations.  

- Lab Reports (20%): Experiment documentation and analysis.  

- Quizzes/Assignments (15%): Weekly problem sets.  

- Participation (5%): Engagement in discussions and activities.  

Conclusion

This course lays the groundwork for mastering chemistry concepts and fostering effective teaching strategies. Consistency, curiosity, and collaboration are key to success!
