4. Chemical Reactions (22 lessons)

Concepts Chemical reactions occur when atoms rearrange themselves into different bonds. Many reactions can be categorized into six basic reaction types. We can use our knowledge of reaction types to predict what products a given set of reactants might produce. Stoichiometry is a tool for theoretically calculating the amount of products/reactants involved in a reaction.Continue reading “4. Chemical Reactions (22 lessons)”

3. Energy (13 lessons)

Concepts Energy is movement or the ability to produce movement. Energy can take many forms, but the forms we will focus on in this course are chemical potential energy (positional), thermal kinetic energy (heat), and electromagnetic energy (radiation). (First law of thermodynamics): in a closed system, no matter what processes occur, the total amount of energy will be conserved. KineticContinue reading “3. Energy (13 lessons)”

2. Bonding (15 lessons)

Concepts (Non-polar) covalent bonds form between atoms of identical electronegativity.  The atoms will share electrons to complete their valence shells. Ionic bonds form between atoms of very different electronegativity.  Because one type atom is pulling electrons so much harder than the other, it actually “steals” the other atom’s electrons until each has a full valenceContinue reading “2.
