Magnesium combustion requires oxygen and nitrogen, and nitrogen does not act in the same way as oxyg

According to the periodic law, the nitrogen atom has a certain oxidation but is weaker than the oxygen atom, so the nitrogen atom can react with magnesium element. However, the nitrogen atom in nitrogen is a diatomic molecule formed by the combination of nitrogen and nitrogen triple bonds, and the energy of this bond is higher, so it is stable, and because it is stable, it does not support combustion (insert a sentence, the concept of combustion support is relative).However, when magnesium is burned in the air, the heat emitted can break the triple bonds of nitrogen and nitrogen and turn them into nitrogen atoms, so that magnesium can react with nitrogen to form magnesium nitride.

From the above explanation, we can see that the role of oxygen and nitrogen is the same, both act as oxidants.

First of all, your question: the role of nitrogen in the combustion of magnesium is similar to that of oxygen, both of which are substances that support combustion, which is also what we call combustion in a broad sense.

Second, nitrogen does not burn, but it can support combustion under certain conditions, magnesium can be burned in nitrogen, but even if there is no nitrogen, as long as there are other substances that support combustion (such as oxygen and chlorine).

Magnesium is burned in the air, most of it reacts with oxygen to form magnesium oxide, and a small part reacts with nitrogen to form trimagnesium dinitride, 3mg+n2=mg3n2

It has the same effect, both of which play an oxidizing role. Certain metals can be burned in nitrogen. It's like it can be burned in carbon dioxide.

Nitrogen works similarly to oxygen in that it acts as an oxidant.

Magnesium is burned in nitrogen to produce magnesium nitride.

The combustion of magnesium in oxygen is that it burns violently and emits a dazzling strong light, which emits a large amount of heat to produce a white powdery solid.

Magnesium has strong reducing properties, can react with boiling water to release hydrogen, and can produce dazzling white light, magnesium and fluoride when burning.

Cavity hydrofluoric acid and chromic acid do not interact and are not attacked by caustic alkalis.

However, it is highly soluble in organic and inorganic acids, and magnesium can be directly combined with nitrogen, sulfur and halogens.

Organic chemicals, including hydrocarbons, aldehydes, alcohols, phenols, amines, lipids, and most oils, have little or no effect on magnesium.

Chemical properties of magnesium Wu Huru:

Magnesium does not interact with fluoride, hydrofluoric acid and chromic acid, nor is it attacked by caustic alkali, but it is easily soluble in organic and inorganic acids, magnesium can be directly combined with nitrogen, sulfur and halogens, etc., and organic chemicals including hydrocarbons, aldehydes, alcohols, phenols, amines, lipids and most oils have only a slight or no effect on magnesium.

But and halogenated hydrocarbons.

In the absence of water, the reaction is more vigorous (Grignard reagent is generated.

Magnesium can react with carbon dioxide, so magnesium combustion cannot be done with carbon dioxide fire extinguishers.

Fire suppression. When magnesium is burned in air, it burns violently and emits a dazzling white light, which is exothermic and produces a white solid. In vinegar, bubbles emerge quickly, float on the vinegar surface, and gradually disappear. Some fireworks and flares.

It contains magnesium powder, which takes advantage of the dazzling white light that magnesium emits when burned in the air.

Magnesium ignites in the air, emits a dazzling glow (with water mist), and is formed as a white solid (white smoke). Magnesium ignites in oxygen and burns violently, emitting a dazzling white light that is formed by a white solid (white smoke). Differences:

White smoke will appear, but when ignited in oxygen, because it is in a gas collection cylinder, the volume is certain, and the white smoke is more obvious.

Magnesium is a metallic element Bukai, and the element symbol is MG. In 1808, David of England used potassium to reduce magnesium oxide to make magnesium metal. It is a silvery-white light alkaline earth metal with active chemical properties, which can react with acid to generate hydrogen, and has certain ductility and heat dissipation.

Magnesium is widely distributed in nature and is one of the essential elements of the human body.

It is often used as a reducing agent to replace metals such as titanium, zirconium, uranium, and beryllium. It is mainly used in the manufacture of light metal alloys, ductile iron, scientific instruments and Grignard reagents. It can also be used to make fireworks, glitter powder, magnesium salt, aspirators, flares, etc.

The structural characteristics are similar to aluminum, which has various uses as a light metal, and can be used as an alloying material for aircraft and missiles. But magnesium is flammable at the ignition point of gasoline, which limits its application.

Magnesium is a common metallic element that can be burned in both air and oxygen. However, there are some differences in the process of magnesium combustion in different environments. First of all, magnesium burning in the air produces a white flame, but the combustion rate is slower, and the resulting magnesium oxide has a high melting and boiling point, which is not volatile.

Secondly, the flame in which magnesium burns in oxygen is bright and rapid, and even a harsh white light appears. At the same time, oxides also take on another form, which is magnesium hydroxide, which is easily soluble in water. As a result, the combustion of magnesium in oxygen releases more intense energy and the fire becomes more intense.

However, in real life, we don't often see magnesium burning in oxygen. Because oxygen itself is very difficult to form, the oxygen content in the air is usually only about 20%. Therefore, when we use magnesium products in our daily lives, we usually only see its combustion process in the air.

However, if we use tools such as magnesium lighters in small spaces, we need to be especially careful, because the deflagration of magnesium in a confined space can pose a threat to our safety.

In general, although there are some areas in the combustion process of magnesium in air and oxygen, we only need to pay attention to its use in a well-ventilated environment to avoid fire and safety accidents when using magnesium products.

2mg+O2=(ignition)=2mgo

Glows white glow and vibrato, forming a white solid.

3mg+n2=(ignition)=mg3n2

Glows white and generates a white solid.

2mg+CO2=(ignition)=2mgo+c

Glows white, generating white and black solid ashwagandha.

Therefore, the phenomenon of liquid notification is not the same. Hope.

Magnesium burns in oxygen, emitting a dazzling white light, while producing a white solid (which is magnesium oxide). Bureau of repentance.

Magnesium burns in nitrogen and emits a dazzling white light to produce a white solid (trimagnesium dinitride).

In carbon dioxide, it emits a dazzling white light, producing white (magnesium oxygen) and black pre-Zheng (carbon elemental) solids.

I haven't done the experiment, but I know the principle... The first two are chemical reactions and the last one is a displacement reaction.

The generated are all black beams, and there should only be the first flame base beam, which is bright and bright, and there is no obvious difference between the others.

The reaction speed and intensity are different, and the phenomenon will be different.

Magnesium is a reactive metal, and under ignition conditions, magnesium can react with nitrogen to form Mg3N2

3mg+n2=(ignition)=mg3n2

Combustion is divided into broad and narrow senses, and the combustion here refers to combustion in a broad sense, and combustion in a broad sense refers to all reactions that shine and heat. In the narrow sense, combustion refers to the violent oxidation of substances by oxygen to produce a reaction of light and heat.

This reaction should belong to combustion in a broad sense, but to be precise, it should be a chemical reaction, but the reaction is more violent, and it also produces light and heat, which can be regarded as combustion. For example, the combustion of coal, the combustion of paper, and the combustion of gasoline are all reacting with oxygen and are burning in a narrow sense.

Magnesium is a relatively reactive metal, which can react violently not only with oxygen, but also with nitrogen and even carbon dioxide, although the phenomenon is roughly the same, it can produce light and heat, which is considered to be combustion. However, the reaction between magnesium and nitrogen and carbon dioxide is different from the reaction between magnesium and oxygen, and the essence should be seen through the phenomenon.
