Burning (an oxidation reaction) is a chemical change,
yes, because it is combusting and providing energy. also when something is burned that is a sign of a chemical reaction taking place
Yes, burning methanol is a chemical change because it involves a chemical reaction in which methanol reacts with oxygen to form carbon dioxide and water, releasing energy in the form of heat. This process is irreversible and results in the formation of new substances with different properties compared to the original methanol.
Yes, it is a chemical change.

When anything is burned a chemical change occurs. The chemical composition of charcoal changes.
When methanol burns and leaves a residue, it undergoes a chemical change. The burning of methanol involves a combustion reaction, where the methanol is reacting with oxygen to form new substances, such as carbon dioxide and water. The residue left behind is a result of this chemical reaction.
Yes, when methanol is burned, it undergoes a chemical change, resulting in the formation of water vapor (H2O) and carbon dioxide (CO2) as products. The residue left behind after burning methanol is typically minimal and mostly consists of non-volatile impurities rather than the original methanol compound.
Combustion is a chemical change. You would expect methanol to be fully oxidised to CO2 and water. Any residue could may be due to impurities or more likely to incomplete combustion which produced sooty carbon residues.
