Make an equation of reactions involving hydrochloric acid and potassium, hydrochloric acid and barium, hydrochloric acid and aluminum

Let’s compose the equations of the described reactions:
1.With the participation of hydrochloric acid and potassium:
2K + 2HCl = 2KCl + H2
2.Containing hydrochloric acid and barium:
Ba + 2HCl = BaCl2 + H2
3.Containing hydrochloric acid and aluminum:
2Al + 6HCl = 2AlCl3 + 3H2
