· What happens when metals react with water?Give examples.

Answer» <p>when metal react with water in presence of oxygen then rusting takes place.such as-rusting of iron, copper becomes greenish etc.</p> <p>All the alkalimetals reactvigorously with coldwater. In eachreaction, hydrogen gas isgivenoffandthemetalhydroxide is produced. The speedandviolence of thereactionincreases as you go down the group.</p> <p>All the alkalimetals reactvigorously with coldwater. In eachreaction, hydrogen gas is given offandthemetalhydroxide is produced. The speedandviolence of thereactionincreases as you go down the group. This shows that the reactivity of the alkalimetalsincreases as you go down Group 1</p> <p>Most of the metals do not react with water. However, alkali metals react vigorously with water. Reaction ofsodiummetal with water:Sodiummetal formssodiumhydroxide and liberates hydrogengasalong with lot of heat when reacts with water.</p> <p>its causes rusting........</p> <p>........................</p> <p>it causes rusting is the correct answer</p> <p>All the alkalimetals reactvigorously with coldwater.
