it goes from +1 to 0

No, it is not a redox reaction. None of the oxidation numbers changes during the reaction. You have to determine the oxidation number for each element and see if it changes from reactant side to product side. If the oxidation number doesn't change, it is not a redox reaction.
This is an oxidation-reduction reaction.

Na+ + NO3- --> NaNO3 The oxidation sum is zero for NaNO3.

Yes it is.
Mg equals Mg2+ plus 2e-
KClO3 --> KCl + 3O2 is a decomposision or breakdown reaction or reversed oxidation
Mg equals Mg2+ plus 2e-
This is an oxidation reaction of N from -3 (in NH3) to +2 (in NO) oxidation value. 4 NH3 + 5 O2 --> 6 H2O + 4 NO
Fe
i can't really read that reaction but! if there is an element by itself in either the reactant or the product side of the reaction QUICKLY think REDOX because the oxidation states for ANY element is 0 by themselves and when they form compounds they either oxidize or reduce to their oxidation state hope i helped
It is the direct combination of two elements or oxidation of copper. 2Cu + O2 = 2CuO its a synthesis reaction!
Mg + KCl
