yes charcoal is simply carbon. Though other impurities may be present.
Gunpowder is not a pure substance. It is a mixture composed of potassium nitrate, charcoal, and sulfur in specific proportions. Each of these individual components maintains its chemical identity in the mixture.
When anything is burned a chemical change occurs. The chemical composition of charcoal changes.
Physical - it's still charcoal.

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.
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.
there are two types of change. the first one is the physical change. the form or appearance of the substance is change but the chemical properties of the substance is not changed. example, water evaporates into the air, that is a physical change because from liquid, water changes into gas but it then comes back to water as rain. the other one is chemical change wherein the chemical properties of the substance is changed. example is burning of wood. wood is burned and turned into charcoal. the chemical properties of wood is different from the chemical properties of charcoal and charcoal is another substance.

Charcoal is a mixture of carbon and several impurities as ash.
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.
Charcoal is a mixture of carbon and several impurities as ash.
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.

Decolourizing charcoal works by adsorbing impurities and pigments from a substance through a process called adsorption. The porous structure of the charcoal traps these molecules within its pores, leaving the substance with a cleaner, clearer appearance.
