High-speed camera reveals details of potassium-water explosion

SOLVED: Potassium reacts with water to produce potassium hydroxide and hydrogen. The balanced equation for this reaction is 2K 2H2O -> 2KOH H2. How many moles of potassium must be reacted with water to produce 0.075 moles of potassium hydroxide when there is an excess of hydroxide?

Walking Water Experiment

SOLVED: Post-Laboratory Questions1. Is the process of dissolving potassium nitrate in water spontaneous at all temperatures used in this experiment? What value do you look at to determine this?2. Is the process of dissolving potassium nitrate endothermic or exothermic? How do you determine?3. Does the value for ΔS make sense in terms of order and disorder?4. Use the standard molar entropies below to calculate the standard molar entropy change for dissolving KNO3 in water. S values: KNO3 13
