What is the product of the combustion of magnesium ribbon?

magnesium oxide
Oxygen and magnesium combine in a chemical reaction to form this compound. After it burns, it forms a white powder of the magnesium oxide. Magnesium gives up two electrons to oxygen atoms to form this powdery product.

What is the ignition temperature of magnesium ribbon?

Magnesium is also flammable, burning at a temperature of approximately 2500 K (2200 °C, 4000 °F). The autoignition temperature of magnesium is approximately 744 K (473 °C, 883 °F).

What type of reaction is mg O2 → MgO?

Mg + O2 → MgO is a Combination reaction.

What happens when you burn magnesium ribbon?

When magnesium ribbon is burnt in the air, it combines with oxygen to form white powder magnesium oxide MgO with the release of heat and light. It forms a white powder of magnesium oxide. Magnesium gives up two electrons to oxygen atoms to form this powdery product.

What is the formula for a magnesium ribbon?

Formula: Mg. Description: Magnesium ribbon is an element and a metal. It is silver coloured, very light and really quite reactive. It will react steadily with diluted acids and release hydrogen gas, it will also ignite whilst it is heated in air, emitting a quite brilliant white glow.

What is the autoignition temperature for magnesium turnings?

Autoignition temperature is for Magnesium turnings or ribbon. Explosion: Fine dust dispersed in air in sufficient concentrations, and in the presence of an ignition source is a potential dust explosion hazard. Minimum explosible concentration 0.030 grams/liter. Water used on molten magnesium will produce hydrogen gas and may cause an explosion.

Why should a magnesium ribbon be cleaned before burning in air?

The magnesium ribbon should be cleaned before burning in the air because the layer of magnesium oxide (which is formed due to the reaction of magnesium with air ) can be removed in order to get the desired chemical reaction. Also in order to remove the oxide layer, the presence of which slowdowns the oxidation process.

How is magnesium ribbon used in pyrotechnics?

It is used in pyrotechnics to produce certain firework mixtures or to ignite thermite reactions. Magnesium ribbon is one of the most common ways to ignite chemical reactions that require a higher temperature to ignite. The only downside to Magnesium ribbon is that it has a tendency to blow out in the wind,…
