The most usual reaction is Fe + PbSO4 => FeSO4 + Pb. This reaction can be called "displacement", "single displacement", or "electromotive displacement", and in all of the names previously given, "displacement" could be replaced by "replacement".
The reaction is:Fe + PbSO4 = Pb + FeSO4
A. Fe^2+ ==> Fe^3+ + e- is an oxidation reactionB. Fe^3+ +e- ==> Fe^2+ is a reduction reactionC. Fe(s) ==> Fe(l) is neither an oxidation nor a reduction reaction. It is a phase change.D. Fe + 2e- ==> Fe^2+ is not a possible reaction.
Fe + 3AgNO3 ==> Fe(NO3)3 plus 3Ag The oxidation number of Ag in AgNO3 (on the left side) is 1+ and in Ag (on the right side), it is zero. Thus, in this reaction, silver (Ag) has been reduced.
The oxidation half-reaction for the given equation is: Fe → Fe2+ + 2e-. This represents the loss of electrons from iron (Fe) to form iron ions (Fe2+).
The balanced chemical equation for the reaction is: 3FeO4 + 8Al -> 4Al2O3 + 3Fe Therefore, the coefficient of Fe is 3.
The reaction is:Fe + PbSO4 = Pb + FeSO4
The chemical reaction is:Pb(NO3)2 + Fe SO4 = PbSO4(s) + Fe(NO3)2
4Fe + 3O2 = 2Fe2O3 in the presence of water.
A. Fe^2+ ==> Fe^3+ + e- is an oxidation reactionB. Fe^3+ +e- ==> Fe^2+ is a reduction reactionC. Fe(s) ==> Fe(l) is neither an oxidation nor a reduction reaction. It is a phase change.D. Fe + 2e- ==> Fe^2+ is not a possible reaction.
Ag+
This is a single displacement reaction, specifically a redox reaction. In this reaction, iron displaces copper from copper sulfate to form iron sulfate and copper.
Fe + 3AgNO3 ==> Fe(NO3)3 plus 3Ag The oxidation number of Ag in AgNO3 (on the left side) is 1+ and in Ag (on the right side), it is zero. Thus, in this reaction, silver (Ag) has been reduced.
Fe
Any reaction occur.
The oxidation half-reaction for the given equation is: Fe → Fe2+ + 2e-. This represents the loss of electrons from iron (Fe) to form iron ions (Fe2+).
The ferrous oxide is the oxdant.
The balanced chemical equation for the reaction is: 3FeO4 + 8Al -> 4Al2O3 + 3Fe Therefore, the coefficient of Fe is 3.
