Charcoal is actually heavier than water with a density ranging from 180kg/m3 to 220kg/m3 ,but wood charcoal is porous with many holes in it and contains air this helps in its floating while when air is removed by boiling it settles down
Depends on what the charcoal is made of, some sinks, some floats.
Carbon monooxide is a gas; CO has a low solubility in water (approx. 25 mg/L at 20 0C).
I think it does
no
One can easily confirm the presence of charcoal powder in Mno2 by heating on a charcoal block
Yes and no it depends on what the powder is, water will dissolve salt sugar and other powder like them but will not dissolve most other things, it usually only lets in things that can make a hydrogen bond.
so in charcoal powder it could be used,especially if you are in the place which are not easily getting materials like in a rural place, so in that case the charcoal powder is used in getting fingerprint impression.
To separate powdered charcoal from a mixture containing copper oxide, just add water. Charcoal is considered quite a bit less dense than water and one set of tables gives the density as circa 400 kg.m-3 . Copper oxide is much more dense than water or charcoal. So the copper oxide will sink to the bottom and the charcoal will float to the top of the water. This can now be decanted and filtered leaving the charcoal on the filter paper which can be dried and to leave charcoal. Then with a separate filtration, the copper oxide and traces of water can be filtered and then dried.

A piece of charcoal is heavier than water but it floats due to it's highly porousness
Water is about 5 times more dense than charcoal. Charcoal floats. (Anything less dense than water floats. More dense than water, it sinks in water)
Because that piece of charcoal is lighter that the water, so it floats.
Sulfur powder will float on the surface of the water.
Yes

Pre-mixed in water containted in plastic bottles or as a powder
The simple answer is yes it can float until it becomes waterlogged.
