Patassium and water = potassium hydroxide and hydrogen .
The reaction equation is
2K(s) + 2H2O(l) = 2KOH(aq) + H2(g)
However, this reaction releases a lot of energy (heat), which makes the released hydrogen react with atmospheric oxygen to form (more) water.
2H2(g) + O2(g) = 2H2O(l)
Potassium , like all Group (I) metals reacts vigorously/violently with water, to the point of flames and explositivity.
The Group 1 element potassium (K), which is an Alkali metal, will react with water (H2O) to form potassium hydroxide (KOH) and hydrogen gas (H2). The balanced equation is here:
2K + 2H2O => 2KOH + H2 (gas)
The word equation for potassium reacting with water is: potassium + water → potassium hydroxide + hydrogen gas.
You should get two compounds.
Potassium Hydrate = H2OK
and
Sodium Hydrate = H2ONa
The word (equation)/name is 'potassium hydroxide'. Its chemical formula is 'KOH'. However, for it to be an equation, what do you want to react with it????
The word equation for potassium bromide and iodine water is: potassium bromide + iodine water -> potassium iodide + bromine.
The word equation for the reaction between potassium chloride and water is: potassium chloride + water → potassium hydroxide + hydrochloric acid.
The symbol equation for potassium with water is: 2K(s) + 2H2O(l) → 2KOH(aq) + H2(g). The word equation is: Potassium + Water → Potassium hydroxide + Hydrogen gas.
Potassium + Water → Potassium hydroxide + Hydrogen gas
