Course Description:
This course introduces students to the fundamental concepts in chemistry. It explores the structure of the atom, bonding between atoms/particles, the concept of the mole, redox reactions, kinetic theory and energetics. A laboratory component will be used to aid in the understanding of these topics.
Course Rationale:
CHEM 101 seeks to enlighten students about the historical development of the structure of the atom and the forces that keep subatomic particles together. It also looks at the importance of intramolecular and intermolecular forces of attraction and how these are linked with the kinetic theory of matter. It further deepens students’ knowledge of the mole concept and introduces the concept of energetics.
General Objectives:
At the end of this course, participants will be able to: Content:
1. Understand the theory of atoms
2. Appreciate that the forces of attraction between particles influence the properties and behavior of matter
3. Understand the mole concept
4. Understand redox reactions
5. Understand the kinetic theory
6. Understand concepts associated with energy changes
Unit Objectives
Understanding the theory of atoms
At the end of this unit, students should be able to:-
1. Discuss the process of theoretical change with respect to Dalton’s atomic theory

9. Describe qualitatively the lattice structure of crystalline solids and their relation to physical properties
Understanding the mole concept
At the end of this unit, students should be able to:-
1. Apply Avogadro’s law
2. Define the terms: mole and molar mass
3. Write balanced molecular and ionic equations
4. Perform calculations based on the mole concept
5. Apply the mole concept to molecular and ionic equations

Understanding the concepts associated with energy changes
At the end of this unit, students should be able to:-
1. State that chemical reactions take place through energy changes(usually in the form of heat) associated with bond breaking and bond forming
2. Explain the differences between exothermic and endothermic reactions using energy profile diagrams
3. Explain the term bond energy and how it may be used to show the relationship between strength of covalent bonds and reactivity of covalent molecules
