Look all correct to me.  The only one I'm not sure about is #6, but I have no better suggestions for the answer since it seems a bit ambiguous.

Agreed.  Catalysis is commonly represented by chemical symbol such as Pd. or Pt. but the answer may be as simple at writing Cat. over the arrow which is often shorthand in biocatalyzed reactions.

[Yggdrasil]

or just writing the enzyme name for biocatalyzed reactions

[cdementor]

It looks perfect to me. Good job. What level are you in?

Wouldn't the answer to question 8

8. The reaction 2Mg(s) + O2(g) --> 2MgO(s) is classified as a(n) _______ reaction.

be oxidation since

1. Oyxgen is added to Magnesium

and more importantly

2. Magnesium is oxidized to Mg²⁺ by the loss of

You are right about the oxidation, but the question most likely asks to classify the reaction as either synthesis, analysis, replacement or double replacement.

Oh I see.

More a "fill in the blanks from this 'ere list" kind of question.
