Why does magnesium react mildly with cold water but

Thus, the metal surface is dynamically dressed by hydrogen atoms and thereby screened from further attack by water.Hence, the reaction is mild in cold water. When the magnesium metal is exposed to hot water or steam, the temperature of the metal increases and its interatomic bonds loosen (destabilise) making the magnesium atoms to give away

Steam Side Burning. Steam side burning is a chemical reaction between steam and the tube metal. It is caused by excessive heat input or poor circulation, resulting in insufficient flow to cool the tubes. Under such conditions, an insulating superheated steam film develops.

CHAPTER3 Metals and Non-metals

Recall from Chapter 2, how copper oxide reacts with hydrochloric acid. We have learnt that metal oxides are basic in nature. But some metal oxides, such as aluminium oxide, zinc oxide show both acidic as well as basic behaviour . Such metal oxides which r eact with both acids as well as bases to produce salts and water are known as amphoteric

Why does magnesium react mildly with cold water but

Thus, the metal surface is dynamically dressed by hydrogen atoms and thereby screened from further attack by water.Hence, the reaction is mild in cold water.
