Yes, when magnesium reacts with hydrochloric acid it is a single replacement reaction. The same is true for nearly all cases of a reaction between an acid and a metal.
One is Shrek element B while the other two are Dreck elements C and A
2Fe (s) + 3Cl2 (g) ----> 2FeCl3 (s)
3K2O + 2Fe
2Fe + 3s = Fe2S3

decomposition
2Fe + 3Cl2 --> 2FeCl3
2Fe + 02 --> 2FeO (depending on the type of iron)
2Fe (s) + 3Cl2 (g) ----> 2FeCl3 (s)
One is Shrek element B while the other two are Dreck elements C and A
Carbon
3K2O + 2Fe
2Al + Fe2O3 -> Al2O3 + 2Fe the thermite reaction-
replacement
Iron oxide is produced.The chemical reaction is given as 2Fe+3H20=Fe2O3+3H2
Fe2O3 + 2Al --> Al2O3 + 2Fe molar ratio = 1:2
