Potassium metal placed in a beaker of hydrochloric acid solution.Write balance equation,type of reaction and symbol of the state?

2K(s) + 2HCl(aq) -> 2KCl(aq) + H2(g)

This is a single displacement reaction.

Symbol of the state:
s - solid
aq - aqueous
g - gas

Balanced Equation:

2K(s) + 2HCl(aq) → 2KCl(aq) + H2(g)

Type of Reaction:

Single displacement reaction

Symbols of State:

- (s) represents the solid state (potassium metal)
- (aq) represents the aqueous state (hydrochloric acid and potassium chloride dissolved in water)
- (g) represents the gaseous state (hydrogen gas released)
