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

Yes, the coating on a magnesium strip can affect the mass of magnesium oxide because the coating can add additional mass to the strip. When the magnesium reacts with oxygen to form magnesium oxide, the mass of the coating is also included in the total mass of the resulting compound.

Why is there a dull white coating on magnesium?

The dull white coating on magnesium is likely magnesium oxide, which forms when magnesium reacts with oxygen in the air. This oxide layer acts as a protective barrier for the underlying magnesium metal, preventing further oxidation.


Why must the surface coating of Magnesium Oxide be removed prior to determining the mass of magnesium used in the experiment?

The surface coating of Magnesium Oxide can add extra mass to the sample, leading to an inaccurate measurement of the pure magnesium used in the experiment. Removing the coating ensures that only the actual magnesium content is being measured, improving the precision and accuracy of the results.


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.


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.


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.


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).


Is magnesium metal and magnesium ribbon the same?

Yes, magnesium metal and magnesium ribbon are essentially the same. Magnesium ribbon is simply a thin strip or ribbon of pure magnesium metal.


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 number of moles of magnesium in a strip of magnesium with a mass of 0.1126g?

To find the number of moles of magnesium, we first need to calculate the molar mass of magnesium, which is 24.305 g/mol. Next, we convert the mass of the strip to moles using the formula moles = mass/molar mass. Plugging in the values, the number of moles of magnesium in the strip is 0.00463 moles.
