If I take a lump of elemental potassium and toss it into a lake, it will most definitely draw some attention. It will react violently with water to produce a hydroxide compound and elemental hydrogen. How can I correctly write this balanced chemical equation?
a. K(s) + H₂O(l) → KOH(aq) + H(g)
b. P(s) + H₂O(l) → POH(aq) + H(g)
c. K(s) + H₂O(l) → KOH(aq) + H₂(g)
d. 2K(s) + H₂O(l) → K₂OH(aq) + H(g)
e. 2K(s) + 2H₂O(l) → 2KOH(aq) + H₂(g)
