With which of the listed substances will hydrochloric acid react? Write down the equations of the corresponding reactions. Pt, Fe, MgO, NaCl, KO

Let’s write down the reaction equations.
HCl + Pt – the reaction does not proceed, since platinum is not an active metal and is after hydrogen in the row of metal activity.
HCl + Fe = FeCl2 + H2
Let’s arrange the coefficients:
2HCl + Fe = FeCl2 + H2 – the reaction refers to substitution reactions.
HCl + MgO = MgCl2 + H2O
Let’s arrange the coefficients:
2HCl + MgO = MgCl2 + H2O – the reaction refers to exchange reactions, it proceeds to the end, as water is formed.
HCl + NaCl – the reaction does not proceed.
HCl + K2O = KCl + H2O
Let’s arrange the coefficients:
2HCl + K2O = 2KCl + H2O – the reaction refers to exchange reactions, it proceeds to the end, as water is formed
