The balanced equation is:
2K + 2H2O -> 2KOH + H2
Therefore, the amount of H2 produced is 1.
The balanced equation is:
2K + 2H2O ---> 2KOH + H2
According to the equation, for every 2 moles of K (potassium) and 2 moles of H2O (water), you will produce 2 moles of KOH (potassium hydroxide) and 1 mole of H2 (hydrogen gas).
Therefore, the correct answer is 2 moles of H2.
