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.
Yes, the reaction between Zn and CuCl2 to form ZnCl2 and Cu is a redox reaction. Zinc (Zn) is oxidized to form Zn2+ ions, while copper (Cu2+) is reduced to elemental copper (Cu).
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 redox reaction you provided is unbalanced. The correct balanced redox reaction should be 2Cl + Br2 -> 2Cl- + 2Br. This balanced equation ensures that both charge and mass are conserved during the reaction.
This is a 'Sngle Displacement' reaction ( A + BC --> AC + B
Silver (Ag)
Yes, the reaction is a redox reaction. Zinc (Zn) is oxidized to form zinc chloride (ZnCl2) while hydrogen ions are reduced to form hydrogen gas (H2).
In the redox reaction, silver (Ag) has been reduced because it gains electrons in forming solid silver (Ag) from silver nitrate (AgNO3).

In the redox reaction AgNO3 + NaNO3 + Ag, silver (Ag) is reduced from Ag+ to Ag with the gain of one electron. Therefore, one electron is transferred in this reaction.
Yes, this is a redox reaction because there is a transfer of electrons between the reactants (Al losing electrons to become AlCl3, which is reduced, and H+ ions gaining electrons to become H2 gas, which is oxidized).
