(why)(At 288K, vs. mol/L) The metal covered with hydroxide has smaller reaction Li+ has hydrated water molecules。(M+/M)(V) n Why Li is the most powerful reducing metal among the alkali metals?n Which one, Li or Na, reacts with water more vigorously? Why?The atypical property of lithiumSmaller radius results in higher hydration energyKiic factors determine the chemic
