Accepted Answer
Question:

1g Potassium (K) + 400ml Water (H2O)

Solution: Potassium hydroxide (KOH) and hydrogen gas (H2)
Chemical Equation: 2K(s) + 2H2O(l) → 2KOH(aq) + H2(g)
Explanation: Potassium (K) is a highly reactive alkali metal. When it reacts with water (H2O), it produces a violent reaction. The reaction is exothermic, releasing a lot of heat and causing the hydrogen gas (H2) produced to ignite. The potassium hydroxide (KOH) dissolves in the water, forming a strongly basic solution. 💥🔥
