Hon Chemistry 1-31-22 Percent Yield

HON CHEMISTRY: So are you a cookie dough lover? Not me – I like my cookies crispy!

Here’s the last of the applications of stoichiometry problems – percent yield. Lots easier that limiting reactants I think. You realize what we’ve done… we’ve finished the chapter!! Now let’s see if you can apply what you know – good times!

Physics 1-26-22 Stability & Torque 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 1-25-22 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! πŸ™‚

  • Chemistry 1-24-22 Describing Chemical Reactions

    CHEMISTRY: So you learned last semester how to determine if a chemical reaction has taken place. How would you go about describing a chemical reaction to someone? Here’s our discussion from today on writing balanced chemical equations!

    First step in writing equations? Make sure you can write chemical formulas! First step to that? Memorization!!

    So tell me again – how do you know if a chemical reaction has occurred? Here’s another hint – not necessarily a good idea to try to make your own blue flame thrower! Click here to watch the Periodic Videos Blue Flame Thrower Video
