No. It must go through a chemical reaction to be a chemical change.
In example, burning a candle: Is it still the same thing before and after you lit it? yes.
So if in the process of burning the leaf it went through a chemical reaction, then it would a chemical change. Since only its appearance changes, not its chemical structure on the molecular level, it is only a physical change.
Burning a tree is a chemical change because the wood undergoes combustion and produces new substances like ash, smoke, and gases. The original wood is transformed into new compounds with different properties during the burning process.
Because when you burn a leaf, it is changing its chemical composition. It's no longer celulose (and the other components), but it is converted to carbon dioxide (CO2) and water in the form of vapor.
Yes as the mollecular structure has been altered and new substances are fromed
Yes, all types of burning are chemical changes because the chemicals are reacting and becoming a different chemical.
Combustion is a chemical change, so the burning of a tree will be a chemical change.

Is a tree burning to form ashes a physical or chemical change?
The process of a tree burning to form ashes is a chemical change. This is because the chemical composition of the tree is altered as it undergoes combustion, transforming into new substances such as carbon dioxide, water vapor, and ash.
Is hammering metal into a flat sheet physical or chemical change?
A physical change means converting how an object looks or feels. Water changed into ice or water would be a physical change. Breaking, bending, melting, evaporating are all physical changes. A chemical change would be changing an object into something you can't change back. Taking bark off a tree (physical) and burning it is a chemical change. Chemical change means burning, rusting, and combustion. I hope this helped. Nossy
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.
Classify the following as a chemical or physical property or change. A tree is struck by lightning. why?
The tree being struck by lightning is a chemical change because it involves a transfer of energy that can cause chemical reactions in the tree, such as burning or decomposition. This changes the tree's composition and cannot be easily reversed.
Is a tree burns to form ashes chemical change?
The parts of the tree that burn are undergoing a chemical change. The ashes remaining may or may not have undergone a chemical change, depending on the the chemical bonding that the atoms in the ash had before the tree was burned.
Is a tree burning a chemical or physical change?
Combustion is a chemical change, so the burning of a tree will be a chemical change.
Is a tree being burned a chemical or physical change?
burning of tree or wood is an irreversible chemical change
Is a tree burning to form ashes a physical or chemical change?
The process of a tree burning to form ashes is a chemical change. This is because the chemical composition of the tree is altered as it undergoes combustion, transforming into new substances such as carbon dioxide, water vapor, and ash.
Is a tree that caught on fire a chemical change?
burning or tree or wood is an irreversible chemical change.
Is burning a tree chemical or physical?
Burning a tree involves a chemical reaction where the bonds in the tree's organic matter are broken down, releasing energy in the form of heat and light. The process of combustion changes the chemical composition of the tree's material, transforming it into ash, gases, and energy.
Is a tree burning into gas a chemical or physical change?
It is a chemical change since it isn't a tree or even any wood of any sort since the wood has combined with oxygen. If you would cut a tree down and make wood planks, it would still be wood (physical).
A tree dies is that physical or a chemical change?
Chemical

A tree burning down and becoming ash
