JKW Lab

Quiz:

Know IGE and GGE forwards and backwards. Remember that the relationship between a gas and dissolving that gas into water is the moles (they don’t change… see the video below).  Also remember the partial pressure problems - know Dalton’s law of partial pressures.

Know the basic thermo and Hess law terms (define/apply) and a basic problem.

WPR:

Think the Quiz plus 2 lessons (explosives). We have the calorimetry lab in class (I’ll demo it this week: add 2 M NaOH and 2 M HCl together and monitor temperature). If you max the quiz, you’ll have the majority of it covered. If not…

~ 6 min

~ 7 min

~ 20 min, long but great imo

Think about combining concepts into a more complicated problem.

Covers Lsns 1-11. You get your calculator, RDC, and pencils.

Do not study by yourself. Groups are better for problem solving UNLESS you find yourself being LEAD/SPOON FED… if so, find yourself the time to re-work

Go over old WPRs and ensure you can do *every* problem.

Go over as many Combustion (2 variants: CxHy only and CxHyOz) as possible.

Go over as many Limiting Reactant problems as possible.

When I’m authorized to return Quiz #2 I will. Ensure you can max it.

Know the naming flow chart.

HOFBrINCl

Fig. 2.19 with Tables 2.3 and 2.4

element - defined by protons (Atomic Number)

ion - defined by electrons (monatomic or polyatomic)

isotope - defined by neutrons (carbon-12, carbon-13 etc)

Know all Define/Apply terms from the GLOSSARY!!!

Pay special attention to the word problems (like the last one on Quiz 2) where you have to tease out: A) the chemical formula that you need to balance; B) Chemical formulas for individual compounds so you can calculate molar masses; and C) the data you want to start with for your picket fence.

Always start your picket fence with what you want to find, like this (fake numbers):
