Chemistry 2-8-23 Single Replacement Reactions & the Activity Series

CHEMISTRY: Great job with single replacement today. Super important – ALWAYS check the activity series!!

We’ve done 15 so far – how are you doing on memorizing them?! Careful though, don’t just memorize. Make sure you can apply them as well. When you start to work any equation, first determine what type of reaction it is, then figure out what rule applies and follow it to determine the products. I believe in you! You can do it!!

Chemistry 2-7-23 Activity Series & Reactions with Oxides

CHEMISTRY: What!?! You mean there aren’t little green people on lonely country roads? 😉

Great job applying the activity series to synthesis and decomposition reactions! As you practice, go back and check the activity series and your notes on the activity series!

HW UPDATE: Because we didn’t finish single replacement reactions today, the book homework for tonight is cancelled for now. BUT that just means you have extra time to study for the quiz on Friday!

We’ve done 10 so far – how are you doing on memorizing them?! Careful though, don’t just memorize. Make sure you can apply them as well. When you start to work any equation, first determine what type of reaction it is, then figure out what rule applies and follow it to determine the products. I believe in you! You can do it!!

Hon Chemistry 2-6-23 Chapter 9 Test Overview & a Look at Advanced Problems

HON CHEMISTRY: I still say stoichiometry is a lot like baking – sometimes you just have to get in there and get your hands dirty! Here is our overview of the test from today and a look at a couple of of the advanced stoichiometry problems. I also found the rusted iron problem work all the way out from last year, so I’m posting that below as well.

Again I want to emphasize – the majority of the test is basic reaction stoichiomety, limiting reactants and percent yield. Be sure and give that the most of your study time!

Also, review writing and balancing chemical reactions. Most of the stoichiometry problems will require that you begin by doing just that! There will be just one extra jumbo large problem. You’ve got this!! 🙂

Physics 1-25-23 Stability & Rotational Equilibrium Problems Review

PHYSICS: Ohhhhhhhhh….so that’s how they can walk across that line! Wait – why do they keep moving their bodies?? Great opportunities for discussion and application!?!

Here’s the discussion from today on how stability relates to center of mass. At the beginning, a quick look at a couple of torque problems from the homework, Torque Worksheet 2.

Hon Chemistry 1-25-23 Limiting Reactant Review & Lab Heads Up

CHEMISTRY: Great job with the limiting reactant problem today! Remember a couple of things – for each problem, you know it’s a limiting reactant problem when they give you the amounts of two reactants, so you are going to have to work TWO different stoichiometry problems. At the end, the reactant that gives you the least amount of product is your limiting reactant. Label it! Also, that answer is the right amount of product. Box it!

And speaking of finding limiting reactants, lets do it for real in lab tomorrow. Will you be ready?

Hon Chemistry 1-24-23 Limiting Reactants

HON CHEMISTRY: So if you have 11 roller wheels, how many roller blade skates can you make? You know, really, limiting reactant is almost that simple. Well, the concept is anyway! You deal with limiting reactants in your life all the time. Now we’re just applying that same concept with chemical reactions! 🙂
