it does not change -apex
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.
Fe
Na+ + NO3- --> NaNO3 The oxidation sum is zero for NaNO3.

Mg equals Mg2+ plus 2e-
Yes, the reaction H2 + Br2 -> 2HBr is an oxidation-reduction (redox) reaction. In this reaction, hydrogen is oxidized from 0 to +1 oxidation state, and bromine is reduced from 0 to -1 oxidation state, indicating transfer of electrons between elements.
Mg equals Mg2+ plus 2e-
Fe
Mg equals Mg2+ plus 2e-
The change in enthalpy equals the heat in a chemical reaction when the reaction occurs at constant pressure.
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
Mg + KCl
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
