Insolubility in water
One key chemical property of carbon is that it can create 4 covalent bonds. Carbon can connect itself along in amazing chains. Chains of Carbon capped-off with Hydrogen form "hydrocarbons" - a term we normally associate with substances we use as fuels.
There is a readable, brief summary of Carbon at: http://www.canadaconnects.ca/chemistry/1009/
When anything is burned a chemical change occurs. The chemical composition of charcoal changes.
Physical - it's still charcoal.

yes charcoal is simply carbon. Though other impurities may be present.
Its a chemical change because the properties of charcoal are changing when fire makes contact with it. It is realising energy and that is one of the most important signs to know if it is a chemical reaction.
A dark or black porous carbon prepared from vegetable or animal substances.
When anything is burned a chemical change occurs. The chemical composition of charcoal changes.
Charcoal burning on the grill is a chemical change because the charcoal undergoes a chemical reaction with oxygen to produce heat and new chemical compounds like carbon dioxide and water vapor.
Crushing charcoal into powder is a physical change, as it alters the size and shape of the charcoal without changing its chemical composition.
Three transformations that can occur in charcoal include: Physical transformation: Charcoal can change its shape and size through processes such as crushing or compressing. Chemical transformation: Charcoal can undergo chemical reactions, such as combustion or oxidation, which alter its composition. Thermal transformation: Charcoal can be heated to high temperatures, which can affect its physical and chemical properties.

Charcoal is a form of potential energy, specifically chemical potential energy, that is stored in its carbon bonds. When charcoal is burned, this energy is released as heat and light.
Charcoal is not a source of light, so it does not have a specific wavelength associated with it. Wavelength is a property of light.
Many nonmetals are brittle and Carbon is a non metal. Charcoal is a carbon compound so charcoal is brittle having the physical property of carbon.
Chemical property because acid is a chemical
Yes it is, in the sense that virtually anything can be classed as a chemical substance if regarded that way. Coconut charcoal is very porous indeed - more so than charcoal obtained from other sources.
