There will be an strong exothermic reaction which will flame and sputter.
that would be a acid-metal oxide reaction see related link for more info
synthesis reaction
Ther is no reaction that occurs because potassium is a more active metal and cannot be displaced by the iron (a weaker metal)

It is basically a REDOX reaction. Extremely reactive in this case
The reaction between potassium and hydrochloric acid is very violent, even explosive. On contact with the acid the reaction rapidly releases heat and hydrogen gas, which ignites. This in turn sets the potassium on fire. When this happens the potassium may explode, scattering flaming molten globules of metal.

No, it is a single displacement reaction. It can also be called a redox reaction. It is not an acid base reaction because although hydrochloric acid is obviously and acid, magnesium is a metal, not a base.
If you added potassium to hydrochloric acid, it would produce potassium chloride (a potassium salt) and hydrogen gas as in the equation below:2K(s) + 2HCl(aq) --> 2KCl(aq) + H2 (g)This reaction is the same for all metals.Acid + Metal = Metal salt + Hydrogen gasOther reactions:Adding an acid to a metal hydroxide gives a metal salt and water.Adding an acid to a metal carbonate give a metal salt and carbon dioxide gas.
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.
Given the general equation:acid + metal ---> salt + waterSo, the only difference between a reaction with a metal and hydrochloric acid or sulfuric acid is the salt formed, a chloride and a sulfate respectively.
3K2O + 2Fe
either potassium, sodium, zinc, iron or copper !
synthesis reaction
The reactants in this reaction are sodium (Na) and hydrochloric acid (HCl).
Ther is no reaction that occurs because potassium is a more active metal and cannot be displaced by the iron (a weaker metal)
The reaction produces hydrogen gas as will most reaction between an acid and a metal.
