What does a magnesium strip look like before it is burnt?
It has the appearance of a thin silver-coloured ribbon.
Does the magnesium strip resemble Mg?
yes of course
Does a magnesium metal strip rust when put in hydrochloric acid?
No
Does magnesium react with nitrogen gas?
yes, the burning strip of Magnesium in nitrogen atmosphere produces solid Magnesium nitride, 3Mg + N2 = Mg3N2
Word equation for hydrochloric acid and magnesium?
Mg + 2HCl → MgCl2 + H2 magnesium+Hydrochloric acid→magnesium chloride+water (H2O)
What does a magnesium strip look like before it is burnt?
It has the appearance of a thin silver-coloured ribbon.
What is the coating on a magnesium strip?
Magnesium oxide. It's produced by magnesium reacting with oxygen.
How and why does the mass of a magnesium strip change when it is heated strongly in air?
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).

yes of course
Does a magnesium metal strip rust when put in hydrochloric acid?
No
Does magnesium react with nitrogen gas?
yes, the burning strip of Magnesium in nitrogen atmosphere produces solid Magnesium nitride, 3Mg + N2 = Mg3N2
What is a balanced chemical equation for magnesium strip and KCl?
There is NO reaction at all.
When was magnesium oxide found?
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.
What will happen if I drop a strip of burning magnesium into a beaker of water?
It will stop burning
What is the number of moles of magnesium in a strip of magnesium with a mass of 0.1126g?
0.1126g Mg/(24.305g Mg) = 0.004632792 moles Mg You're welcome, noob.
Word equation for hydrochloric acid and magnesium?
Mg + 2HCl → MgCl2 + H2 magnesium+Hydrochloric acid→magnesium chloride+water (H2O)
Is burning a strip of magnesium ribbon a chemical or physical change?
This is a chemical change. The reaction is: Mg + O ---> MgO
