Why does crucible and its contents gain mass as a result of heating magnisium in the air?
When magnesium is heated in the air, it undergoes a chemical reaction with oxygen to form magnesium oxide. This reaction increases the total mass of the crucible and its contents due to the addition of oxygen atoms from the air. The increase in mass is a result of the combination of magnesium and oxygen to form magnesium oxide.
Does Magnesium Ribbon evaporate?
Magnesium ribbon does not evaporate in the traditional sense. When heated to high temperatures, magnesium undergoes a chemical reaction known as oxidation, where it combines with oxygen from the air to form magnesium oxide. This process is not considered evaporation.
What do you observe when magnesium ribbon is heated to form magnesium oxide?
When magnesium ribbon is heated, it reacts with oxygen in the air to form a white powder, which is magnesium oxide. This reaction is exothermic, producing a bright white light and a release of heat. The magnesium ribbon disappears as it combines with oxygen to form the solid magnesium oxide.
Why does the mass of magnesium sulfate decrease when heated?
It does not decrease in mass, only weight, the mass is still all there, but as when it has been heated smoke is given off from the element, and goes into the atmosphere. It may not sound like the mass is all there with the heated element, but if the smoke were conserved during the experiment the weight would be the same as before the experiment.
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 combined wih the magnesium when it was ignited in The Crucible?
oxygen. O2 was combined with magnesium when it ws heated in the crucible
Why is it essential for magnesium chloride solution in the crucible to be heated slowly?
If the solution is not heated slowly, the solution could boil over resulting in lost mass and calculation errors
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 --> Mg3N2By 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 + 2NH3After heating the magnesium hydroxide, the product becomes just magnesium oxide.3Mg(OH)2 + heat --> MgO + H2OIn 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.
What is the chemical name for heated magnesium?
That would be Magnesium Oxide (since a single element cannot decompose) which decomposes into Magnesium and Oxygen. Magnesium Oxide --> Magnesium + Oxygen or the balanced chem. equation: 2MgO --> 2Mg + 02

What is the use of crucible?
A crucible is used to contain chemical compounds when heated to extremely high temperatures.
What are the uses of clay triangle?
Clay triangle is used to hold a crucible while the crucible is heated.
What is the name of the compound formed when magnesium and sulfur are heated?
The compound formed when magnesium and sulfur are heated is magnesium sulfide (MgS).
