- Description
-
Chemistry is a laboratory-based college-preparatory course. Laboratory experiments provide the empirical basis for understanding and confirming concepts. This course emphasizes discussions, activities, and laboratory exercises, which promote the understanding of the behavior of matter at the macroscopic and the molecular-atomic levels. Chemical principles are introduced so that students will be able to explain the composition and chemical behavior of their world. Chemistry AB lays the foundation for further studies in Chemistry and also serves as an Advanced Placement Chemistry readiness course. Chemistry AB meets the Grades 9–12 District physical science requirement. Students must complete one physical and one life science requirement.This course meets one year of the University of California ‘d’ entrance requirement for laboratory science

Finals
The final will consist of five misconceptions. Students will need to make the corrections and explain why the error is incorrect using chemical vocabulary.
Soon to come is a review sheet of the possible misconception topics.

Fall final review topics
Each statement is a misconception. On the final, the statement must be corrected and justified. Focus on the proper use of vocabulary to explain why the statement is false.
1. Hydrogen is drawn in a Lewis Structure having more than two electrons.
2. Sodium chloride is considered to be a molecule with linear directional bonding.
3. Water is a linear molecule.
4. Bar graphs are used to represent independent continuous data.
5. An ionic bond is occurring when the electrons are transferring from one atom to the other.
6. Intramolecular forces are weaker than intermolecular forces.
7. Molecular shape is larger upon heating. A molecule in the gas phase is much larger in size than the same molecule in the solid phase.
8. Boiling is the maximum temperature a substance can reach.
9. One pound of bricks weighs more than one pound of feathers. One mole of bricks has the same mass as one mole of feathers.
10. Air and oxygen are the same gas.
11. Particles of solids have no motion.
12. Freezing and melting points occur at different temperatures.
13. Mass and volume represent the same measurement.
14. Only mercury can be a liquid metal.
15. According to the Bohr’s model of an atom all energy levels have equal intervals (distance between energy levels).
16. Atoms have electrons circling around the nucleus like planets around a star.
17. Particles can expand, burn, change shape.
18. Matter disappears or is destroyed.
19. One mole of hydrogen gas weighs less than one mole of hydrogen liquid.
20. The size of an atom depends on the number of protons.

Group Assignment*
During the Fall break, think about two comparable chemicals.** You will need to argue which is better based on chemical justification.
The following must be covered in the description portion of the activity:
- Chemical name
- Chemical formula
- Chemical structure
- Chemical bonding (Ionic, Covalent, Metallic)
- Intermolecular forces
- Chemical and Physical properties
*This will be revised through out the break. A final draft will be available to students in class on 11/30.
**The chemical can be the main component/ingredient in a chosen object. For example, Tylenol's main ingredient is acetaminophen or blue jeans' main component is cellulose.
