Question

a) Write the chemical reaction of Magnesium with i) oxygen ii) water iii) acid

Answer 1

Explanation:

Chemical equation of Mg with Oxygen :-

• 2Mg + O2 → 2MgO

Here, Magnesium reacts with oxygen to form Magnesium oxide.

Chemical equation of Mg with Water :-

• Mg + 2H2O → Mg(OH)2 + H2

Here, Magnesium reacts with water to form Magnesium hydroxide and evolve hydrogen gas.

Chemical equation of Mg with Acid :-

Here, we take HCl acid :-

• Mg + 2HCl → MgCl2 + H2

Here, Magnesium reacts with Acid to form Magnesium chloride and hydrogen gas.

Answer 2

Answer:

MG with oxygen:

• 2Mg + O2 → 2MgO

Here, Magnesium reacts with oxygen to form Magnesium oxide.

MG with water:

• Mg + 2H2O → Mg(OH)2 + H2

Here, Magnesium reacts with water to form Magnesium hydroxide and evolve hydrogen gas.

MG with acid:

Here I have taken HCI acid

• Mg + 2HCl → MgCl2 + H2

Here, Magnesium reacts with Acid to form Magnesium chloride and hydrogen gas.
