You need to do these yourself. What do you not understand about this question?
Aqueous solutions that end up with solids usually are pptn reactions. Loss/gain electrons in a reaction are redox reactions. Those that produce water, especially if they are from OH and H containing compounds, usually are acid/base reactions.
Classify the following reactions as precipitation reactions, oxidation-reduction reactions, or acid-base reactions.
1)2NaCl(aq)+K2H2Sb2O7(aq)==Na2H2SbO7(s)+2KCl(aq)
2)(CH3COO)2Cu(aq)+(NH4)2C2O4(aq)==CuC2O4(s)+2CH3COONH4(aq)
3)4Al(s)+3O2(g)==2Al2O3(s)
4)2Zn(s)+O2(g)==2ZnO(s)
5)Zn(s)+Cu^2+((aq)==Zn^2+(aq)+Cu(S)
6)Mg(OH)2(aq)+2HCl(aq)==2H2O(l)+MgCl2(aq)
7)3NaOH(aq)+H3PO4(aq)==Na3PO4(aq)+3H2O(l)

Precipitation: #'s 1,2
Oxidation-reduction: #'s 3,4,5
Acid-based: #'s 6,7
**similar to the ones on mastering chem, or at least that's how I answered them. And hey we all need a little help, even if its 3 years later. I hope this helps someone else who needs a lil break
