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 reaction represented by Fe + CuSO4 → Cu + FeSO4 is a single displacement reaction, also known as a single replacement reaction. In this process, iron (Fe) displaces copper (Cu) from copper(II) sulfate (CuSO4), resulting in the formation of iron(II) sulfate (FeSO4) and elemental copper. This type of reaction typically occurs between a more reactive metal and a compound of a less reactive metal.
The reaction between 3Fe and 4H2O to form Fe3O4 and 4H2 is a reduction-oxidation (redox) reaction. In this process, iron (Fe) is oxidized to form Fe3O4, while water (H2O) is reduced to produce hydrogen gas (H2). The transfer of electrons between the reactants characterizes this type of reaction.
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+).
