In a single replacement reaction, iron (Fe) can replace nickel (Ni) in nickel(II) chloride (NiCl₂) because iron is more reactive than nickel. The reaction can be represented as:
[ \text{NiCl}_2 + \text{Fe} \rightarrow \text{FeCl}_2 + \text{Ni} ]
This produces ferrous chloride (FeCl₂) and solid nickel (Ni) as products.
The thermite reaction is:Fe2O3 + 2 Al = 2 Fe + Al2O3
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.

Iron (Fe) has an atomic number of 26, which means it has 26 protons. The most common isotope of iron, iron-56 (Fe-56), has 30 neutrons (56 - 26 = 30). Therefore, a single Fe²⁺ atom, which has lost two electrons but retains the same number of protons and neutrons, still contains 30 neutrons.
The thermite reaction is:Fe2O3 + 2 Al = 2 Fe + Al2O3
A single replacement reaction will not occur. In a single replacement reaction, either a metal will replace another metal in a compound, or an anion will replace another anion in a compound. Click on the related link to see the Wikipedia article on single displacement (single replacement).
Fe + NaCl --> Na + FeClThis is called single replacement.
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.
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".
Displacement reaction , as HCl displaces S of FeS to give H2S
Fe+CuSO4^Cu+FeSO4
fe+3=..............* .9 =fe+2
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 the ion Fe(3+).
When you mix sulfuric acid (H2SO4) with iron (Fe), the iron reacts with the acid to form iron sulfate (FeSO4) and hydrogen gas (H2) is released. This reaction is known as a single replacement reaction.
