Why is water added to The Crucible in order to complete the conversion to magnesium oxide?
Water is added to the crucible to convert magnesium (Mg) to magnesium oxide (Mg(OH)2) because when magnesium reactions with air, it also reacts with the nitrogen (N2) in the air to form magnesium nitride (Mg3N2).
3 Mg + N2 --> Mg3N2
By adding water to the crucible containing the magnesium nitride, the magnesium nitride will become magnesium hydroxide. The ammonia gas produced will rise out of the crucible, eliminating the nitrogen.
Mg3N2 + H2O --> 3Mg(OH)2 + 2NH3
After heating the magnesium hydroxide, the product becomes just magnesium oxide.
3Mg(OH)2 + heat --> MgO + H2O
In other words, when water is added, the nitrogen will react with the water, causing it to form ammonia and thus evaporating from the substance. This leaves behind the magnesium hydroxide, which becomes magnesium oxide and water after it is heated.

How tp prepare magnesium acetate?
To prepare magnesium acetate, you can react magnesium oxide or magnesium hydroxide with acetic acid. Start by adding magnesium oxide or hydroxide to acetic acid in a controlled manner while stirring until the reaction is complete. Filter the solution to remove any insoluble impurities, and then evaporate the solvent to obtain solid magnesium acetate.
How much sodium hydroxide in grams must be added to seawater to completely precipitate 86.9mg of magnesium?
To completely precipitate 86.9mg of magnesium from seawater, you would need to add an equal molar amount of sodium hydroxide. The molar mass of magnesium is about 24.3 g/mol, so 86.9mg is equivalent to about 3.57 mmol of magnesium. You would need the same amount of mmol of sodium hydroxide to completely precipitate the magnesium.
Why does magnesium get heavier when its burned?
When magnesium is burned, it combines with oxygen from the air to form magnesium oxide. This reaction increases the overall weight of the magnesium because the newly formed magnesium oxide has a greater mass than the original magnesium metal due to the added oxygen atoms.
What Is The Precipitate Of Sodium Hydroxide Magnesium Sulphate?
Magnesium Hydroxide since in the Solubility Rules it states that "All hydroxides are insoluable exceptcompounds of the alkali metals, Ca2+, Sr2+ and Ba2+" and since Magnesium is not in any one of those on the list Hydroxide is insoluable and therefore the precipitate.
Which gas is produced when Mg(s) is added to HCl(aq)?
Hydrogen gas (H2) is produced when magnesium (Mg) reacts with hydrochloric acid (HCl) because magnesium displaces hydrogen from the acid to form magnesium chloride and hydrogen gas. This is a single replacement reaction where more reactive metal displaces less reactive hydrogen from the acid.
When added with acid which metal reacts fastest iron or magnesium?
magnesium
What gas was produced when water is being added to Magnesium Oxide?
When water is added to magnesium oxide, magnesium hydroxide is produced. This reaction also releases heat.
What happens if magnesium ribbions is added in acetic acid?
When magnesium ribbon is added to acetic acid, a chemical reaction occurs which produces hydrogen gas and magnesium acetate. The magnesium ribbon will dissolve as it reacts with the acetic acid, releasing bubbles of hydrogen gas in the process. This can be observed by the fizzing or bubbling that occurs.
When magnesium carbonate is added to dilute hydrochloric acid what salt does it form?
Magnesium Chloride. MgCO3 +2HCl -----> MgCl2 + CO2 + H2O
What happens when magnesium oxide is added to water the salt will be?
When magnesium oxide is added to water, it will react to form magnesium hydroxide, a salt solution, and release heat. This reaction is exothermic and the magnesium hydroxide formed will be a white solid that will dissolve in water to form the salt solution.
What happens when dilute hydrochloric acid is added to magnesium?
When dilute hydrochloric acid is added to magnesium, a chemical reaction occurs where hydrogen gas is produced and magnesium chloride is formed as a product. The reaction can be represented by the equation: Mg + 2HCl -> MgCl2 + H2.
What colour does magnesium turn added with water and universal indicator?
When magnesium is added to water with universal indicator, the indicator may initially turn blue (indicating a basic solution due to the formation of magnesium hydroxide) before turning back to its original color as the magnesium metal reacts with water to form magnesium hydroxide and hydrogen gas.
How tp prepare magnesium acetate?
To prepare magnesium acetate, you can react magnesium oxide or magnesium hydroxide with acetic acid. Start by adding magnesium oxide or hydroxide to acetic acid in a controlled manner while stirring until the reaction is complete. Filter the solution to remove any insoluble impurities, and then evaporate the solvent to obtain solid magnesium acetate.
When magnesium is added to a jar of nitrogen what happens?
If magnesium is added to a jar of nitrogen, there will be no immediate reaction as magnesium does not react with nitrogen in its elemental form. Magnesium does react with nitrogen under specific conditions, such as in the presence of a catalyst or at high temperatures.
When solid magnesium carbonate is added to a lot of hydrochloric were does the solid magnesium carbonate go?
They react to form H2CO3 and MgCl2
What colour does hydrochloric acid go when magnesium is added?
When magnesium is added to hydrochloric acid, a chemical reaction takes place, resulting in the formation of magnesium chloride and hydrogen gas. The color of the hydrochloric acid does not change significantly during this reaction.
Which gas is produced when Mg is added to HCl?
h2
