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 the appearance of combustion product of magnesium strip?
When a magnesium strip is burned, it produces a bright white flame and forms magnesium oxide as the primary combustion product. The magnesium oxide appears as a white powdery residue, which can accumulate on surfaces or in the air as white ash. The intense light and heat produced during the combustion can also cause nearby materials to ignite.
Which one has adhesive coating that is protected by a strip of brown waxed coating?

What happens to magnesium when you heat it up?
When magnesium is heated up, it reacts with oxygen in the air to form magnesium oxide. This reaction is exothermic, producing a bright white light as the magnesium burns. Magnesium oxide is a white powdery substance left behind after the reaction is completed.
Why copper wire is appropriate choice to secure magnesium strip?
Copper wire is a good choice to secure a magnesium strip because copper does not react with magnesium, so it will not interfere with the chemical properties of the magnesium strip. Additionally, copper is malleable and ductile, making it easy to wrap around and secure the magnesium strip in place.
What is the coating on a magnesium strip?
Magnesium oxide. It's produced by magnesium reacting with oxygen.

The mass of the strip increases because magnesium combines with oxygen atoms from the air to form a heavier compound (magnesium oxide).
Is burning a strip of magnesium ribbon a chemical or physical change?
Burning a strip of magnesium ribbon is a chemical change because the magnesium reacts with oxygen in the air to form magnesium oxide. This reaction results in the formation of new substances with different properties than the original magnesium ribbon.
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.
Why is the magnesium strip polished before weighing?
The magnesium strip is polished before weighing to remove any surface impurities, such as dirt or oxidation, that could affect the accuracy of the measurement. By ensuring the strip is clean and free of contaminants, the weight obtained will be more accurate and reliable.
What is the appearance of combustion product of magnesium strip?
When a magnesium strip is burned, it produces a bright white flame and forms magnesium oxide as the primary combustion product. The magnesium oxide appears as a white powdery residue, which can accumulate on surfaces or in the air as white ash. The intense light and heat produced during the combustion can also cause nearby materials to ignite.
What is the effect of HCl on burned Mg strip?
When HCl is added to a burned Mg strip, it will react with the magnesium oxide formed during the burning process, producing magnesium chloride and water. The reaction will produce fizzing or bubbling due to the release of hydrogen gas. Overall, the HCl will dissolve the magnesium oxide and form a solution of magnesium chloride.

Does the magnesium strip resemble Mg?
Yes, a magnesium strip is made of elemental magnesium (Mg). It is typically a thin piece of solid magnesium metal that can be used for different chemical reactions or experiments.
What happens to magnesium when you heat it up?
When magnesium is heated up, it reacts with oxygen in the air to form magnesium oxide. This reaction is exothermic, producing a bright white light as the magnesium burns. Magnesium oxide is a white powdery substance left behind after the reaction is completed.

Does M9 paper have adhesive coating that is protected by a strip of brown waxed paper?
No, M9 paper does not have adhesive coating protected by a strip of brown waxed paper. M9 paper is used for detecting liquid chemical agents on surfaces and does not have any adhesive coating or protective waxed paper strip.
