Question

What is the action on water on sodium, mg,al write equation of the chemical reaction envolved?

Answer 1

Answer:

Na + H2O --> Na2O + H2

Mg +H2O --> MgO +H2

Al + H2O --> Al2O3 +H2

Explanation:

when metals are combined or reacted with water, then they form their respective metal oxides with the release hydrogen.

Metal + Water --> MetalOxide +Hydrogen

metals react with different kinds of water like some react only with cold water some only with steam or cold water. Some of the metals react vigorously (violently) with water, so in such cases heat is also evolved. But in all the cases formation of the respective metal oxide and release of hydrogen is common (only when metal and water actually react).
