Answer:

#"K"_2"O" + "H"_2"O" -> 2"KOH"#

Explanation:

Potassium oxide + water produces potassium hydroxide.

Potassium oxide is an ionic compound. The potassium has a charge of #"K"^+# and oxygen has a charge of #"O"^(2-)#. We need 2 potassium ions to balance one oxide ion making the formula #"K"_2"O"#.

Potassium hydroxide is an ionic compound. The potassium has a charge of #"K"^+# and hydroxide has a charge of #"OH"^-#. We need 1 potassium ion to balance one hydroxide ion making the formula #"KOH"#.

#"K"_2"O" +" H"_2"O" -> "KOH"#

To balance the equation we place a coefficient of 2 in front of the potassium hydroxide.

#"K"_2"O" + "H"_2"O" -> 2"KOH"#

I hope this was helpful.
