Combustion is a process by which substances react with oxygen to produce water and heat. The combustion process is an exothermic process. Fuel is a form of fuel that can be used during combustion. Magnesium powder form is highly explosive, but ribbon form it is not as explosive because the surface area decreases in ribbon shape. Magnesium oxide reacts with air to produce Magnensi oxide. Magnesium’s reaction with the atmosphere is prevented by a layer of magnesium oxide over the magnesium, which would prevent its combustion because combustion requires the interaction of the substance with air.
Why Magnesium Ribbon Is Rubbed Before Burning – Answer & Related Questions
Magnesium’s reaction with the atmosphere is prevented by a layer of magnesium oxide over the magnesium, which would prevent its combustion because combustion requires the interaction of the substance with the air. Hence, removing the layer of magnesium oxide before burning it is vital.
Why Magnesium Ribbon Is Rubbed Are Cleaned Before Burning?
The magnesium ribbon burns in air, resulting in extreme heat and brilliant white light.
The oxygen from the air reacts with magnesium to produce magnesium oxide.
The ribbon’s surface will be sanitized, allowing the ribbon to burn efficiently.
Always remember that magnesium only reacts with oxygen in the air to produce an oxide coating on its surface, but it does not react with atmospheric nitrogen at all.
The reaction to this is the same as the one above: O __2MgO $.
Why Is Magnesium Ribbon Rubbed?
Refrences. Magnesium is a highly reactive metal. When exposed to air, it develops a layer of magnesium oxide on its surface, which prevents further reaction of calcium with oxygen. Because of a layer of basic magnesium oxide, the magnesium ribbon is rubbed before burning.
