Are synthesis reactions redox reactions?
Yes, most of the synthesis are redox reactions!
Can combination reaction be a redox reaction?
Yes it can. I believe that an example of such a reaction would be the addition of zinc to a solution of 6 molar hydrochloric acid (HCl).
What are REDOX reactions?
To put it simply, redox (reduction/oxidation) reactions are a transfer of electrons. In it's most simple form, as a half equation, Cu -> Cu2+ + 2e-. Or as a complete reaction, Zn + Cu2+ -> Zn2+...
Are all reactions redox reaction?
No
Are all combustion reactions redox reactions?
Yes, all combustion reactions are redox reactions because elemental oxygen is a reactant. (Silberberg, "Chemistry The Molecular Nature of Matter and Change" Fifth edition)
