Sodium (Na) has been reduced.
s is positive and g i s negative at all temperatures

This is usually called a "displacement" reaction; a metal higher in the electromotive series is displacing a metal below it in the electromotive series in a compound of the latter.
This is a redox reaction.
Redox reaction.
Oxidation is a redox reaction.
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.
I cannot answer this question.
yes
The overall voltage for a redox reaction with the half reactions Mg s -- Mg2 plus plus 2e- and Cu2 plus -- Cu is 76 V.

This redox reaction also requires an acid as H2SO4 , the overall reaction is.... 5H2C2O4 + 2KMnO4 + 3H2SO4 = K2SO4 + 2MnSO4 + 10CO2 +8H2O
This is a balanced equation and this is a Synthesis type of reaction
This is a 'Sngle Displacement' reaction ( A + BC --> AC + B
