Answer:
Hello buddy
Explanation:
Calcium and magnesium are two metals that start floating after some time when immersed in water.
Explanation: Calcium and Magnesium react with water to form respective hydroxides and release hydrogen gas. The reactions are given as:
Ca + 2H2O → Ca(OH)2 + H2
Mg + 2H2O → Mg(OH)2 + H2
The bubbles of the hydrogen gas so formed in the reaction stick to the surface of the metal surface, and thus the metals float on water.
