Monday Recap
AP: revisited the First Law of Thermo : delta E = q + w ...be wary of the SIGN of q and w based on the conditions given for the process.
We discussed enthalpy which is defined as the heat lost or gained during a CONSTANT PRESSURE conditions. We distinguished between a STATE FUNCTION (P,V,T,E,H,S,G ...all CAPS) and a function that is PATH dependent such as work or heat ( w or q ).
We then went through three algebraic axioms for manipulating delta H when you multiply or flip a balanced thermochemical equation.
We will be using those logical rules when we start doing the alternate form of Hess's Law.
Tomorrow, we will get into how delta H values are experimentally obtained.
Friday is day 6...test day for the Thermo and Gas Units.
Regents: We finished our significant figure and scientific notation lesson. Then, we finished up the evidence that led to the Rutherford Model of the atom; study that picture on page 2 of the orange review book.
Always bring your orange review book and the blue workbook to class; starting tomorrow, we will use them almost daily.
Honors D,G: We finished our significant figure and scientific notation lesson; then we began our introduction to the Bohr Model of the Atom. In order to understand the Bohr Model, you have to know about radiant energy/light; what it is and how it interacts with matter. We will discuss light over the next one or two classes and then relate that information to the light emission spectrum of hydrogen (and other elements) in order to understand the Bohr Model of the atom. I will put up some PowerPoints on that. Tonight, I will also put up some outline notes that you can download and then expand upon as we discuss the Bohr Model in class. I will post the objectives for Friday's Honors exam (yes, it will be given Friday). Start writing your answers to the questions ASAP and then check them at extra help.
G Period: Bring in your LAB FOLDER with the completed LAB SAFETY agreement and lab questions tomorrow, TUESDAY.
I will post a density lab write-up for the Honors and Regents classes by Wednesday. That lab writeup will be due next week.
