why magnisium flots on water |
|
Answer» Magnesium metal does not react with cold water. it react with hot water to form magnesium hydroxide and hydrogen.Mg + 2H2O → Mg(OH)2 + H2in this reaction a piece of magnesium metal starts floating in water due to the bubbles of hydrogen gas sticking to its surface.\xa0 As hydrogen bubbles gets stick to the surface of mg When mg reacts with water....h2 bubbles are produced which get stick to mg and as result it floats |
