Question

Write the chemical equation of the following reactions. •The reaction of Magnesium with water • Reaction of Aluminium with water • Reaction of Zinc with water

Answer 1

Answer:

Mg +H20 =Mg02+H

Al +H20 = Al(OH)3

zn + H20= zn (0H) 2+ H2

Answer 2

Metals react with water and produces metal oxide or metal hydroxide depending upon its reactivity. Hydrogen gas is produced when metals react with water. All metals reacts with water differently.

HIGHLY REACTIVE:

• Metal + Water ➝ Metal hydroxide + Hydrogen gas

LESS REACTIVE:

• Metal + Water ➝ Metal oxide + Hydrogen gas

Chemical Reactions:-

• Magnesium reacts with hot boiling water to form Magnesium hydroxide and hydrogen gas

$\large{ \boxed{ \rm{Mg + H_2O \longrightarrow Mg(OH)_2 + H_2}}}$

• Similarly, Zinc reacts with hot steam to form zinc oxide and hydrogen gas.

$\large{ \boxed{ \rm{Zn + H_2O \longrightarrow ZnO + H_2}}}$

• Aluminium does not react either with cold or hot water, because it is not so reactive. But it reacts only with steam to form aluminium oxide and hydrogen gas.

$\large{ \boxed{ \rm{2Al + 3H_2O \longrightarrow Al_2O_3 + 3H_2}}}$

Sodium and Potassium are highly reactive metals and react with water vigorously. The reaction is very violent and exothermic and in this reaction, hydrogen is produced which catches fire.

Calcium and Magneisum floats in water because of the bubbles of hydrogen formed or produced during this reaction which sticks to their surface making it lighter to float over the surface.
