When methanol is burned and leaves a residue a physical or chemical change?
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.
Is methanol is burned and leaves a residue a chemical change?
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.
Is leaves falling from a tree chemical change or physical?
Leaves falling from a tree is a physical change. It is a change in state or appearance without altering the chemical composition of the leaves.
Is raking leaves a chemical change?
No. If any, it is a physical change because the leaves are moved and torn, but not permenantly changed
Is drying leaves a chemical change or a physical change?
Drying of leaves is a physical change because neither it changes its composition nor does it have any different properties from the original one.

Is a methanol is burned and leaves a residue a chemical change?
Burning (an oxidation reaction) is a chemical change,
Is methanol is burned and leaves a residue a chemical change?

Is copper and silver a chemical or physical change?
It is a chemical change because it leaves a residue (which is a sign of chemical change) Hope that helps
Is leaves decay physical change or chemical change?
chemical change
Is leaves rotting a chemical change or a physical?
It is a chemical change.
Is burning of leaves physical change or chemical change?
Burning leaves would be a chemical change because once the leaves are burnt, you can't turn the ashes back into leaves.
Is a color changing in leaves a chemical change or physical change?
Chemical Change.
Is the change in leaves a chemical or physical change?
The change is leaf color is a chemical change.
Is a color changing in leaves a physical or chemical change?
a chemical change
Is color changing in leaves a chemical change or a physical change?
Color changing in leaves is a chemical change. It involves the breakdown of chlorophyll and the production of other pigments due to chemical processes triggered by factors like temperature and daylight changes. This results in the visible color change in the leaves.
Is leaves falling from a tree chemical change or physical?
Leaves falling from a tree is a physical change. It is a change in state or appearance without altering the chemical composition of the leaves.
