Paper is mostly cellulose, like wood, from which it is made.
It is composed of atoms of carbon and hydrogen and oxygen. When heated, the molecules combine to form carbon dioxide, water, and other oxidized elements (such as calcium and potassium oxides), which form the wood ash. The oxidation is an exothermic reaction as the carbon-hydrogen bonds contain substantial chemical energy.
As with food oxidation (carbohydrates), the energy was stored in the wood by the growth of the plants (trees).
Paper is mostly cellulose strands since it is made from wood or cotton most of the time. Cellulose is a long polymer of glucose, a sugar, that is composed of carbon, oxygen and hydrogen. The exothermic chemical reaction, fire, releases the carbon in up to three forms: elemental carbon, carbon dioxide and carbon monoxide. Meanwhile, the hydrogen combines with any available alcohol group (OH) from the sugar to form water (dihydro-monoxide), a very stable compound. Of course, this perfect picture is complicated by any print or colored inks on that paper which may contain sulfur and by the nitrogen-rich medium in which the chemical reactions happen: air. Here stable nitrogen-oxygen and to a lesser extent nitrogen-hydrogen compounds of nitrogen oxide(NO2 and NO) and ammonia(NH4) respectively may form.
Even though wood is mostly composed of two chemicals, cellulose and lignin, it is a complex product of biological processes and it contains many different chemicals. Some chemicals, when they are burned, produce only gas products, usually carbon dioxide and water vapor. Others produce solid products known as ash.
Ash is a incombustible residue, formed generally from oxides.
because when paper burn it burns some of the mass with it
Put it in water and see what happens?
because there is is a pressure difference between the inside of the bottle and the outside. the pressure is lower in the bottle the egg gets sucked in. when the oxygen is burned there is less matter in the bottle then at first and that results in less pressure[vacuum]
It really depends of the type of paper. Some papers are more alkaline than others.
Mg
smudge it with tissue paper or your finger. this method makes it dry faster, thinner, and also make it whiter.
less
only if the ORIGINAL not REMAINING duration is 3 months or less.
At least 500 dollars for a rifle with 80% of its original finish remaining.
That depends on how much less paper you use...
The value of a firearm depends on the condition it is currently in. It also depends on which model the firearm is. Some models were made in less numbers and therefore are less common and can command higher prices. The closer to original condition as far as the amount of original finish remaining on the wood and/or metal is more desirable to collectors.
less friction then what?
There are only two pieces of pie remaining.
That depends on what it is. If by "original document" you mean a newspaper... moderately so, but lots of people kept those, so they're less rare (and correspondingly less valuable) than you might think. At a rough guess: if it's a major paper from a large city with a large display headline like "JAPAN SURRENDERS" or "PEACE", it might sell for in the vicinity of $50, with considerable variation either way. If it's an obscure paper from a small town, significantly less. If it's a clipping and not the entire paper, it's essentially worthless.
Strictly speaking, it isn't. But many people think it's a great idea. Recycling paper means that less trees gets felled to make paper, and less paper has to go to landfills. Making paper out of paper also use up less energy than making paper from trees, so society save some there too.
Well think, if you burn a piece of paper, then energy is involved. Chemical energy is taking place when you burn a piece of paper. However, two more types of energy are also taking place. Thermal and radiant energy are also taking place because the fire burning the paper creates light (radiant energy) and it also gives off heat (thermal energy).

A paper sinks because it has less density. Paper can get wet because it can hold to much.
