This is a 'Sngle Displacement' reaction ( A + BC --> AC + B
Silver (Ag)
The reduction potential plus oxidation potential is negative.
Combustion reaction
Mg equals Mg2+ plus 2e-
This is a redox reaction.
4Li + O2 -> 2Li2O
This is a 'Sngle Displacement' reaction ( A + BC --> AC + B
yes as zinc is oxidised and hydrogen is reduced
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.
Sodium (Na) has been reduced.
Redox reaction.
Oxidation is a redox reaction.
I cannot answer this question.
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
