Why rubbed magnesium ribbon burns faster than non rubbed magnesium ribbon?
IF the chemical composition is the same in both rubbed and non-rubbed than the only difference could be that oxygen is more readily available in the rubbed ribbon. Which burns faster, 100 lb tree stump or 100 lbs of sawdust made from that tree stump? They are both the same material except one is more solid than the other. The sustained chemical reaction in fire needs: Heat, fuel, and oxygen. Because the rubbed ribbons allow for more oxygen to be present (like saw dust), it will burn faster.
Is magnesium metal and magnesium ribbon the same?
Yes. Magnesium ribbon is magnesium metal in the shape of a ribbon.
Why we rub magnesium ribbon with sand paper before burning it?
We rub magnesium ribbon with sandpaper to remove its oxide layer, which forms naturally on its surface. This oxide layer can inhibit the magnesium from burning efficiently, as it prevents a proper reaction with oxygen. By exposing the clean surface of the magnesium, we ensure a more vigorous and complete combustion when it is ignited. This preparation enhances the magnesium's reactivity and increases the intensity of the flame produced during burning.
Why clean magnesium ribbon with sand paper before weighing it?
Cleaning magnesium ribbon with sandpaper before weighing it removes any surface oxide layer that may have formed, ensuring an accurate measurement of the magnesium's mass. This oxide layer can add extra weight and affect the results of experiments or reactions. Additionally, cleaning the ribbon prepares it for consistent reactivity in chemical reactions, as it exposes the pure metal underneath. Proper preparation is crucial for reliable experimental outcomes.
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.
Is magnesium ribbon pure?
No, magnesium ribbon are not pure. They have to be rubbed with sand paper, this removes the impurities on them

Is magnesium metal and magnesium ribbon the same?
Yes. Magnesium ribbon is magnesium metal in the shape of a ribbon.
Is magnesium ribbon a compound?
No. Magnesium ribbon is nearly pure magnesium, which is an element.
Color of magnesium ribbon?
Magnesium ribbon is silver colored.

Why is mg ribbon cleaned to use of sand paper before burning?
The magnesium ribbon is cleaned with sandpaper before burning to remove any dirt or oxide layers that may inhibit the reaction. This ensures that the magnesium reacts completely when it burns, resulting in a more efficient and successful combustion process. It also helps to ensure a more consistent and reliable reaction when the magnesium ribbon is ignited.
Why is a block of wood get warm when it is rubbed with sandpaper?
because of friction
What is the chemical composition of magnesium ribbon?
that is magnesium itself, in the form of a ribbon
What is the word equation for burning magnesium ribbon?
magnesium + oxygen gas ----D magnesium oxide
Why rubbing of magnesium ribbon with sand paper is done to make better contact with oxygen?
Magnesium, when exposed to air, spontaneously forms a surface oxide of the type known as " passivating", which remains attached to the underlying metal and prevents the oxidation of the underlying atoms by blocking the access of oxygen molecules to them. Sandpaper removes this passivating oxide layer temporarily.
