Does the coating on a magnesium strip change the mass of magnesium oxide?

The mass of the magnesium will be lower than the mass of the magnesium oxide
1 mole of Mg = 24 grams
1 mole of MgO = 24 + 16 = 40 grams

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).

What is a balanced chemical equation for magnesium strip and KCl?
There is NO reaction at all.
When magnesium is burned in air is the product formed heavier lighter or the same mass as the magnesium that you started with?
Both products MgO (magnesium oxide) and some Mg3N2 (magnesium nitride)are both much heavier than the originating Mg strip before it was set to fire.Mg = 12 g/molMgO = (12+16) = 28 g/mol(1/3)Mg3N2 = (1/3)*(3*12 + 2*14) = 0.33*64 = 21 g/mol
What happens to a magnesium strip when put into a flame?
A White Spark Appears As A Chemical Reaction Takes Place In oxygen, it will react to form MgO (magnesium oxide) In nitrogen, it will react to form Mg3N2 (magnesium nitride) In carbon dioxide, it will react to form MgO and CO2 (carbon dioxide)
What is the coating on a magnesium strip?
Magnesium oxide. It's produced by magnesium reacting with oxygen.
Why is the magnesium strip polished before weighing?
To remove the oxide layer (magnesium oxide) on it

Is burning a strip of magnesium ribbon a chemical or physical change?
This is a chemical change. The reaction is: Mg + O ---> MgO
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 is the effect of HCl on burned Mg strip?
Burned Mg would result in formation of magnesium oxide (MgO)Reacting this with HCl ... 2HCl + MgO ==> MgCl2 + H2O

Was a strip of magnesium metal into a solution of copper sulfate a chemical change?
Yes. The magnesium metal replaces the copper in the copper sulfate. This is a single replacement or single displacement reaction.
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
