0.1126g Mg/(24.305g Mg) = 0.004632792 moles Mg
You're welcome, noob.
When a magnesium strip is heated strongly in air, it undergoes a chemical reaction called oxidation. Magnesium reacts with oxygen in the air to form magnesium oxide. The mass of the strip increases because magnesium combines with oxygen atoms from the air to form a heavier compound (magnesium oxide).
There is NO reaction at all.
The mass of the magnesium will be lower than the mass of the magnesium oxide1 mole of Mg = 24 grams1 mole of MgO = 24 + 16 = 40 grams
Copper can't be dessolved by the hydrochloric acid.
It is burning -- oxidizing -- just like a piece ofwood placed in a hot fire.
Magnesium oxide. It's produced by magnesium reacting with oxygen.
To remove the oxide layer (magnesium oxide) on it

yes of course
No
yes, the burning strip of Magnesium in nitrogen atmosphere produces solid Magnesium nitride, 3Mg + N2 = Mg3N2
There is NO reaction at all.
Magnesium oxide is a white, powder-like solid which has no odor. It can be easily produced burning a magnesium strip in air. It is not totally pure as it contains some magnesium nitride also.
It will stop burning
Mg + 2HCl → MgCl2 + H2 magnesium+Hydrochloric acid→magnesium chloride+water (H2O)
It has the appearance of a thin silver-coloured ribbon.
This is a chemical change. The reaction is: Mg + O ---> MgO
