Chemistry 1-25-24 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!

HW UPDATE: On The Physics Classroom assignment for tonight, you do not have to do the last part – Chemical Reaction types. You only have to do Balancing Chemical Equations – complete only 2 levels: Apprentice and Wizard

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?

Hon Chemistry 1-25-24 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! 🙂

HW UPDATE: For Thursday night – Pg. 311 – 314: 25d, 26c, 27b, 35, 40 (only find one product on 25 & 26) – due tomorrow. Lab report for Gases lab is changed to due Saturday, 11:59 PM.
