I'm having a bit of trouble translating what I see when I perform the experiment into actual chemical reactions.  In one experiment, Magnesium is placed in Hydrochloric acid, and a burning splint is extinguished.  So I think that it is producing Magnesium chloride + hydrogen?

The ones I am blank with is Carbon Dioxide bubbling through a beaker of water.  Blue litmus turns red, so it must be acidic.  Carbonic acid?  There's also sodium hydroxide + ammonium carbonate.  I think ammonia gas is produced because of the smell (I think).  But what kind of reaction is that? What does that leave?  I'm not sure..

Acetylene is burned.  C2H2 + O2, is that correct?  I think the product has carbon dioxide in it?  Carbon Dioxide + Water?  Is that the product?  But then what type of reaction would that be?  Just combustion?

Finally ammonium carbonate + hydrochloric acid.  I have no clue about this one.  And Magnesium burning to magnesium oxide, I can just write that as a combustion?

Thanks in advance...

OK

Yep.

There's also sodium hydroxide + ammonium carbonate.  I think ammonia gas is produced because of the smell (I think).  But what kind of reaction is that? What does that leave?

Ammonia evolved. What ions does that leave in the solution?

Acetylene is burned.  C2H2 + O2, is that correct?  I think the product has carbon dioxide in it?  Carbon Dioxide + Water? Is that the product?  But then what type of reaction would that be?  Just combustion?

OK

Finally ammonium carbonate + hydrochloric acid.  I have no clue about this one.

In a way it is similar to ammonium carbonate plus strong base. Just in the first case ammonia was diplaced, in this case weak acid will be displaced.

And Magnesium burning to magnesium oxide, I can just write that as a combustion?

Yep.
