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.
What else can I help you with?
Mg ribbon continuous to burn in presence of CO 2.why?
When magnesium ribbon burns in the presence of CO2, it forms magnesium oxide and carbon. The reaction is exothermic, releasing heat to sustain the burning of the magnesium ribbon. The CO2 supplies oxygen to support combustion.
What happens when magnesium ribbon burns?
When a magnesium ribbon is burned it combines with molecular oxygen forming magnesium oxide (MgO); the flame color is white.A huge spark. Kind of like a firework-ish. You kind of have to see it.
What burns with a bright white light?
Magnesium burns bright white. It is often used in the production of fireworks. Magnesium is the most common metal that burns white, but titanium , aluminum , and beryllium can be mixed to form compounds that also form bright white light.
White ash obtained by burning magnesium ribbon?
The white ash obtained by burning magnesium ribbon is magnesium oxide (MgO). When magnesium burns in the presence of oxygen, it reacts to form magnesium oxide, which appears as a white powdery ash. Magnesium oxide is commonly used in various industrial applications, as well as in manufacturing pharmaceuticals and supplements.
Word eqaution for magnesium burns in oxygen?
2 Magnesium+oxigen- 2 magnesium-dioxide
Whats an advantage for using powdered magnesium for flash photography instead of magnesium ribbon?
The powder burns much faster than the ribbon, providing a quick bright flash. The ribbon would burn more slowly, providing a longer lasting light but not as bright.See the Related Question for why a powdered substance will generally react faster.
What does magnesium ribbon leave after burning?
When magnesium ribbon burns, it produces a bright white light and forms magnesium oxide as a white powder residue.
What element in ribbon form burns with a white light forming ions with a charge of 2?
This describes the behaviour of magnesium.
What will happen when magnesium ribbon is heated?
It is burns and releases a brilliant white flame.
Mg ribbon continuous to burn in presence of CO 2.why?
When magnesium ribbon burns in the presence of CO2, it forms magnesium oxide and carbon. The reaction is exothermic, releasing heat to sustain the burning of the magnesium ribbon. The CO2 supplies oxygen to support combustion.
What happens when magnesium ribbon burns?
When a magnesium ribbon is burned it combines with molecular oxygen forming magnesium oxide (MgO); the flame color is white.A huge spark. Kind of like a firework-ish. You kind of have to see it.
Is heat gven out or taken in from the surroundings when the magnesium ribbon burns in oxygen?
It is given out. If it were taken in, magnesium would not continue to burn when heat were removed.
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.
What burns with a bright white light?
Magnesium burns bright white. It is often used in the production of fireworks. Magnesium is the most common metal that burns white, but titanium , aluminum , and beryllium can be mixed to form compounds that also form bright white light.
Why should you not look at magnesium ribbon when it burns?
Looking at burning magnesium ribbon can cause damage to the eyes due to the intense UV light it emits. This can result in temporary or permanent vision impairment. It is important to wear proper eye protection when observing the burning of magnesium ribbon to avoid eye injury.
Why when magnesium ribbon is burnt the ash is heavier?
When Magnesium burns, it is actually combining with oxygen in the air to form a new compound, magnesium oxide. If we were to carefully weigh a piece of magnesium before and after burning it, you would see that its weight increased by about one third. For example, if you start with 100 grams of magnesium, after the burn you would end up with about 130 grams of magnesium oxide. The fact that the magnesium oxide you create by burning is powdery, means that it takes up more space (size or volume) than the solid magnesium did.
When magnesium burns it forms a chemical what is it called?
Magnesium oxide
