Is the final consumption of a substance combustion, and what is after the combustion of a substance?

1. "If you take it and burn it, it won't be there, and if you can't burn a stone, you can burn it?"

Matter is a higher form of energy, and its basic composition can be traced back to subatoms, which can of course be fissioned or fused, perhaps as LZ calls "burning". It's just that in reality, the nuclear materials used in nuclear reactors depend on their utilization value (whether they are easy to carry out, ** wide and rare, etc.), and a lot of energy will be generated in the process.

2. "What do you do with an object, it's still crushed, it's still there", "Burn it, it's gone".

LZ may have a misunderstanding of the form of existence of matter, and I wonder what LZ means by "not there"? For the time being, even the disintegration of an atom is based solely on the destruction of its stable structure, which decomposes into more elementary particles: neutrons, protons, electrons.

Even more so, such as up and down quarks, to photons, tachyons, and so on. In addition, the use of any substance, to give the most obvious example: "the carbon in the furnace fire burns out".

This is not to say that it has really disappeared from the physical world, but that the carbon atoms in it react with oxygen molecules in the air and exist in the form of carbon dioxide or carbon monoxide, so in a sense, matter is conserved. The "absence" of LZ should mean that it is not observable to the naked eye.

3 Note that the final consumption is associated with the annihilation of antimatter into energy, but still "exists".

Personal opinion, I hope these are helpful to lz.

Matter changes form, but it does not lose mass, and it does not disappear. Unless there is consumption converted into heat energy, if the paper is burned, it is impossible or the paper can still be burned, because if it is consumed, it is gone, can you still turn it back into burning? Energy is consumed

Non also the final consumption is with antimatter annihilation into energy.

Haven't you heard of "bench bombing the earth"?

General chemical definition of combustion: Combustion is a violent oxidation reaction between combustibles and combustibles (oxidants). Broad definition of combustion:

Combustion refers to any violent reaction that emits light and heat, and does not necessarily require oxygen to participate, such as the reaction of sodium metal (Na) and chlorine (Cl2) to form sodium chloride (NaCl), which does not involve oxygen, but is a violent chemical reaction that emits light and heat, and also belongs to the category of combustion. It doesn't have to be a chemical reaction, such as the combustion of nuclear fuel.

Whether they are non-combustible and oxide or do not support combustion depends on the specific composition.

Light and heat? Light and heat are energy, and combustion is the conversion of chemical energy into other forms of energy.

Light is a wave with no end, also called a photon, but it is actually matter. What about the heat?

The law of motion of molecules is that high-temperature objects convert energy into low-temperature objects, and heat energy will release energy to the surrounding low-temperature objects, which move with the motion of molecules.

Isn't matter immortal?

Substances will be transformed into other states, gases, solids, liquids, substances will also undergo chemical changes, so that there are different chemical properties depending on whether the substance supports combustion, etc.

What is left of the substance after combustion?

If the earth can burn, what will burn to the end?

What is when the sun burns out, and the earth burns out about the same.

Isn't it true that the matter that makes up the universe is still nothing?

You should look at Einstein's general and special theories of relativity.

It can be understood as the transformation of quality and energy.

Einstein's theory says q=mc2

That is, the product of the square of the mass and the speed of light is energy.

Therefore, after the combustion of matter, it is energy (matter is completely burned under ideal conditions), which is what I have to understand, hehe.

Combustion is only the transformation of matter, and light and heat are only accessory products.

Because there are no combustibles in the burned substance, it cannot be burned. For example, what remains after the combustion of combustibles in paper is impurities, and the conditions for combustion are:

There are combustibles, there is oxygen or air, to reach the ignition point, all three are indispensable, when the combustibles are gone, it can not be burned, for example, the combustibles in the paper are burned after the remaining impurities, impurities are not combustibles.

This combustion is a redox reaction, when the reducing substances in the paper and coal are oxidized, there is no redox reaction between the reducing substances and oxygen.

Combustion is actually a chemical reaction, after the combustion is over, the flammable substance does not exist, so it is no longer burned.

According to the conservation of nitrogen, the amount of nitrogen before the reaction is equal to the amount of nitrogen after the reaction.

n(cu)=

n(no)+n(no2)=

The amount of n atoms that run out of the solution =

There is also no3- combined with Cu2+ to form Cu(no3)2, so the amount of nitric acid species consumed by the reaction =
