Comments about Q7:
People are confusion jargon, understandable but something that must be avoided. Draw a picture, like day 1 of Ch 7 notes, so you do not confuse the terms
2b(i) people are placing electron on the wrong side of the half reactions. 10 positives on the right (acetylene) need 10 negatives (electrons) to add to zero to equal the zero charge on the Reactant side. If you are unclear about this, ask me before Wed's exam.

Oxidation is loss of electrons, Reduction is gain of electrons
Redox is not just energy: paper, meth on Skunk Hollow, green tea, Harrin Hall

Comments about Quiz 1
Human body is a heterogeneous mixture, with variable composition depending on where your take a sample (bone, blood, brain, muscle, skin). Some mistake a compound (like sugar made of C, H, and O) as a mixture. It isn't. A compound has uniform composition, sugar is sugar, no matter where you draw a sample from a pile of sugar, the composition is the same.
