SOLVED: When potassium metal is placed in water a violent reactionoccurs releasing hydrogen gas and producing the strong basepotassium hydroxide. The equation for this reaction is:2 K (s) 2H2O (l) → 2 KOH(aq) H2 (g) If you placed 13.0 g of K (s) in a 1-liter beaker filled withwater, how many grams of H2 (g) could you possiblyproduce?Question 5 options:0.332 g0.336 g0.168 g0.672 g

💥Some firecracker science just in time for 4th of July🎆 Reaction of potassium with water: alkali metals are extremely reactive with water. When we add a small piece of potassium to water, the metal floats on the water, moving around and fizzing. The fizzing happens because the metal reacts with the water to form hydrogen gas. As potassium is very reactive, the reaction is very vigorous and the potassium burns with a lilac flame. The hydrogen also ignites, producing sparks. The other product of
