single replacement
The thermite reaction is:Fe2O3 + 2 Al = 2 Fe + Al2O3
fe+3=..............* .9 =fe+2
Ag+
2 Fe + 3 CuO -> Fe2O3 + 3 Cu
single replacement
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).
The thermite reaction is:Fe2O3 + 2 Al = 2 Fe + Al2O3
Fe + NaCl --> Na + FeClThis is called single replacement.
Fe+CuSO4^Cu+FeSO4
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(s) + CuSO4(aq)= FeSO4(aq) + Cu(s)
Iron nitrate and copper. Fe + Cu(NO3)2 -> Fe(NO3)2 + Cu
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.
One assumes this is a single displacement reaction. 2Au + FeSO4 --> Au2SO4 + Fe
Ag+
