Tues-Day 2
AP Chem- Note: the following hw questions were not yet covered in class and thus will not be graded tomorrow- 40a, 40d, 40f, 42, and 47.
Also, we will have a 5 to 10 minute descriptive chemistry quiz in which you will write and balance the NET IONIC equation (though you may first write the formula equation as I did in the practice worksheet) and name each of four different reactions that we have covered over the past three months: a gas-forming reaction, a double-replacement with precipitation, an acid-base neutralization, and either a redox combustion or a redox single replacement (anionic or cationic).
An EASY way to practice is for you to make up your own reactions; if you truly take to heart the fact that most members of a given group chemically react/behave the same, all acids and bases react to form a salt and water, all metals will be oxidized to their most stable cations by aqueous solutions of copper II ions, silver ions, or gold ions then you can write out many different reactions already. If you know your solubility rules, you can think up hundreds of double-replacement reactions. Try it and ask me if you're not sure about what you've made up.
Today, we (finally) finished our extensive Lewis Structure/Electron Geometry/Central Atom Hybridization/Molecular Geometry/Molecular Polarity Chart!
I posted a METRIC TON of practice worksheets with which you can apply your new-found talent. Do them and check your answers so that you can ace Friday's exam with EASE (it's been done consistently in recent times though this test is no joke)!
We stepped back to our review of the types of bonding WITHIN a molecule or WITHIN a polyatomic ion and also the bonding BETWEEN/AMONG IONS in a LATTICE of an ionic compound (salt or hydroxide base). We also discussed the unnecessarily confusing concept of ionic CHARACTER and covalent CHARACTER of a given bond; we will elaborate further.
Bio 6- HW Objective Answers are posted; check them vs. your answers as part of your study for tomorrow's exam. I also posted information from our two lab discussions.
Today we finished the unit by summarizing the types of diseases of the integumentary and skeleto-muscular systems. We then discussed/reviewed proper scientific method/experimental design to test a hypothesis regarding muscle groups and muscle fatigue as well as our perspiration simulation lab.
Bio 7/8- HW Objective Answers are posted; check them vs. your answers as part of your study for tomorrow's exam. I also posted information from our two lab discussions.
Today we finished the unit by discussing skin functions, connective tissue and by summarizing the types of diseases of the integumentary and skeleto-muscular systems. We then discussed/reviewed proper scientific method/experimental design to test a hypothesis regarding muscle groups and muscle fatigue. We briefly discussed a perspiration lab; the graph and sample data from that lab are posted.
