What happens when metal reacts with water?

Answer 1

Most metals react VERY slowly, but some react vigorously .Metals will produce either the hydroxide or oxide....

Did that help...?

Hope it did...

BYE :)

Answer 2

The reaction of a metal with water will depend on the particular metal. For example, when sodium metal reacts with water, you have 2Na(s) + 2H2O(l) ==> 2NaOH(aq) + H2(g). This is the case with most group I metals. For group II metals, such as Mg or Cu, you have formation of 1:1 compounds as oxides, i.e. MgO, CaO and 1:2 compounds like in hydroxides, i.e. Mg(OH)2, Cu(OH)2.
Mg + H2O ==> MgO + H2 or Mg + 2H2O ==> Mg(OH)2 + H2

Answer 3

Alkali metals reacts violently with water forming a hydroxide and hydrogen; alkali earth metals react with water but no so violent.
Other metals doesn't generally react with water at room temperature.

Answer 4

When certain metals like sodium or potassium react with water, they release hydrogen gas and form metal hydroxides. This reaction can be quite vigorous and may generate enough heat to ignite the hydrogen gas, producing a visible flame. Other metals like iron or aluminum react more slowly with water due to the formation of a protective oxide layer on their surface.

Answer 5

corrosion, then rust starts to begin.
