Last Class, Mr. Doktor showed us a couple examples of Chemical Reactions.
We have just finished our unit on Moles, and now we are moving up to the next one which focuses on Chemical Reactions. We really didn't talk about what chemical reactions were, but what we talked about are evidences/characteristics that helps us determine whether a chemical reaction has occured or not.
And these are: Fizzling/Bubbling, Precipate Forms, Change of Color (but not often considered as a chemical reaction), Heat and all others that concerns either the absorption or release of energy.
That's practically it. Oh BTW, I really liked the Magnesium Reaction thing, it really looked like an actual firework. Haha.
We'll upload the video as soon as possible.
Ciao!
