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?
