The combustion of wood is a chemical change because the products water, carbon dioxide, soot, and ash, all have physical and chemical properties that are different from the reactants wood and oxygen.

Combustion of wood is a chemical change because it involves the breaking of chemical bonds in the wood molecules to form new substances (such as carbon dioxide and water vapor). A chemical change results in the formation of new substances with different chemical properties than the original substances.

Combustion, or burning, is a chemical change because the resulting product has a different chemical composition that the beginning substance. A physical change would be when the appearance of the object changes, but the chemical composition remains the same.

Is the combustion of wood an example of a physical change?

Combustion (burning) is a chemical change.


Is heating a wood splinter a chemical change and why?

Heating the wood (and not burning it) would be a physical change. If the wood splinter catches fire and burns, then it is a chemical change because a combustion reaction has taken place and the wood is no longer the same chemical composition. It will turn into carbon dioxide and water, and other materials left over.


Is burning logs in a fireplace a physical change or a chemical change?

Burning logs in a fireplace is a chemical change. The wood undergoes combustion, which involves a chemical reaction where the wood reacts with oxygen to produce heat, light, and new substances like ash and smoke.

Is wood turning into ash in a fire a physical change?

Yes, wood turning into ash in a fire is a chemical change because the chemical composition of the wood changes as it is burned. The wood undergoes a combustion reaction with oxygen to form new substances such as carbon dioxide and water vapor.


Wood chemical change?

One common chemical change that wood undergoes is combustion when it is exposed to heat and oxygen, resulting in the release of carbon dioxide, water, and energy. Another chemical change that wood can undergo is fermentation, which occurs when wood is broken down by microorganisms to produce products such as ethanol or acetic acid. Additionally, wood can undergo chemical changes such as oxidation and hydrolysis when it is exposed to certain environmental conditions.


Does a chemical change occur when a piece of wood is painted?

Burning wood a physical or chemical?

Burning wood is a chemical reaction because combustion (burning) is an oxidation reaction.


What is an emample of a chemical change?

Burning wood is an example of a chemical change. In this process, the wood undergoes combustion, reacting with oxygen in the air to produce heat, light, and new substances such as ash and carbon dioxide.


Is burning wood into charcoal a physical change?

Unfortunately, it is not a physical/reversible change, as combustion causes chemicals to change their bonding. A simpler example than wood would be glucose (the same reaction as in respiration): C6H12O6 + 6O2 --> 6CO2 + 6H2O This reaction is not reversible.


Is combustion a physical change or a chemical change?

Combustion is basically a chemical reacting with oxygen to become the oxide and water is produced. So when alcohol combusts, for example, it is changed (burned) to carbon dioxide and water. In other words, there is a chemical change.


What is a wood burning a physical or chemical?

Wood burning is a chemical process known as combustion. During combustion, the wood undergoes a chemical reaction with oxygen in the air, resulting in the release of heat, light, and various byproducts such as carbon dioxide and water vapor.
