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.
What else can I help you with?
What is result if a piece of magnesium ribbon burn and place the white ash in 5ml of water in a test tube with a red litmus paper?
The result would be that the white ash of magnesium ribbon reacts with water to form magnesium hydroxide, which will turn the red litmus paper blue due to the basic nature of the resulting solution.
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.
What causes the movement of the ribbon?
The movement of the ribbon in a typewriter is typically caused by the rotation of the print cylinder or platen, which advances the paper as you type. The ribbon is then positioned between the paper and the typebars, allowing the ink to be transferred onto the paper when a key is struck.
How burning of paper is different from tearing of paper?
because burning of paper is a chemical change while tearing of paper is a physical change
Is burning paper a chemical property?
Burning is a chemical process, not a property.
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.
Is magnesium ribbon pure?
No, magnesium ribbon are not pure. They have to be rubbed with sand paper, this removes the impurities on them
What happen if Get a piece of magnesium ribbon and remove the tarnish with sand paper?
MENOR!
What happens when magnesium ribbon is burnt in air?
Magnesium is an extremely reactive metal. When stored, it reacts with oxygen to form a layer of magnesium oxide on its surface. This layer of magnesium oxide is quite stable and prevents further reaction of magnesium with oxygen. The magnesium ribbon is cleaned by sand paper for removing this layer so that the underlying metal can be exposed to air.
What is result if a piece of magnesium ribbon burn and place the white ash in 5ml of water in a test tube with a red litmus paper?
The result would be that the white ash of magnesium ribbon reacts with water to form magnesium hydroxide, which will turn the red litmus paper blue due to the basic nature of the resulting solution.

What is the NAICS code for carbon paper and inked ribbon?
NAICS Code(s) 339944 (Carbon Paper and Inked Ribbon Manufacturing)
What causes the movement of the ribbon?
The movement of the ribbon in a typewriter is typically caused by the rotation of the print cylinder or platen, which advances the paper as you type. The ribbon is then positioned between the paper and the typebars, allowing the ink to be transferred onto the paper when a key is struck.
Why does a burning paper stopp burning?
the paper will end up running out
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.
What is ribbon carier?
