Why does Mg3N2 form in insufficient air?

Mg3N2 forms in insufficient air because magnesium reacts with nitrogen gas to form magnesium nitride. When there is not enough oxygen present, magnesium is more likely to react with nitrogen to form Mg3N2 rather than magnesium oxide (MgO).

Why is it easier to weigh the product of burning magnesium rather than the products from a bunning candle?

It is easier to weigh the product of burning magnesium because magnesium burns in a highly controlled reaction to produce a single product, magnesium oxide, which can be easily collected and weighed. In contrast, a burning candle produces multiple products such as carbon dioxide, water vapor, and soot, making it difficult to collect and weigh all the products accurately.


Can magnesium float in acids?

no, magnesium never floats in acids...........


How much magnesium is contained in magnesium bicarbonate?

Magnesium bicarbonate is typically produced as a solution rather than a solid compound, so it is difficult to provide an exact amount of magnesium in a specific quantity. The magnesium content can vary depending on the concentration of the solution.


Why might magnesium metal rather than copper metal be used to study the effect of concentration of hydrochloric acid on rates of reactions?

Magnesium metal reacts more vigorously with hydrochloric acid than copper metal, resulting in a more noticeable change in reaction rate. This makes it easier to observe the effect of concentration on reaction rates. Additionally, magnesium is less expensive and more readily available than copper.


What type of reaction is NaCI?

NaCl is not a reaction, but rather a compound.


Will tin and magnesium sulfate react?

This is an exact question from the chemistry lab at SLCC. I wonder if you are in the same lab(?) Anyway, I do not believe that a precipitate will form. Sn would have to replace Mg to form SnSO4. Sn would be oxidized while Mg would be reduced. Based on the standard reduction potentials, Mg is a stronger reducing agent, meaning it would rather be oxidized. Sn is a stronger oxidizing agent, meaning it would rather be reduced. If it was the opposite way around, like if you added Mg to SnSO4, then metallic Sn would form.


What is the chemical formula for magnesium dioxide?

The oxidation of magnesium is a process, and as such has a chemical equation rather than a formula: 2 Mg + O2 -> 2 MgO. MgO is the chemical formula for the oxide of magnesium.


Can magnesium float or is it lighter than air?

Magnesium is denser than air, so it will sink in air rather than float.


What are the advantages of using powdered substances rather than using solid substances?

The advantage is that powdered substances have a much larger surface area than solids. This increased area allows more contact with reactants The speed at which chemicals will react is related to their ability to make contact with reactants. A block of iron will oxidise slowly, as the oxygen can not reach the iron except at the surface. However iron filings will oxidise much quicker because of the increased area available.


Has modernization put an end to discrimination?

No. Rather it has increased it.
