Wood to ash, heat & light.
Burning a log results in the release of heat and light energy, as well as the production of ash and smoke. This process is a chemical reaction where the wood combines with oxygen to form carbon dioxide and water vapor.
While burning a log, you will observe flames and smoke as the wood undergoes combustion. The log will gradually reduce in size as it releases heat and light energy. Eventually, you will be left with charred ash and embers.
Burning a log involves a chemical reaction where the wood undergoes combustion, producing heat, light, and ash. It is not considered a mixture as the log itself is a homogeneous material made up of cellulose, lignin, and other components that undergo a chemical change during burning.
The burning of a log in a fireplace is a chemical change, as the wood undergoes combustion to produce ash, smoke, and gases. The log is transformed into new substances with different properties, such as carbon dioxide and water vapor.
Burning chocolate is a chemical change because the heat causes the chemical structure of the chocolate to change, leading to the release of new compounds and altering the composition of the chocolate.

All its substance goes gone it turns to ashes so it's not wood anymore and it becomes Chemical Change

A log is a mixture regardless of whether it is burning.
Burning the log is a chemical change. All of the others are physical changes.
Yes.
During the burning of a log, you can observe flames, smoke, and glowing embers. As the log burns, it will shrink in size and eventually turn into ash. The color of the flames and the intensity of the heat can vary depending on the type of wood and the conditions of the fire.
Burning a log in the fireplace involves a chemical reaction because it undergoes combustion, reacting with oxygen to produce heat, light, and new chemical compounds like carbon dioxide and water vapor. Sawing a log in half is a physical change where the log is simply being cut into smaller pieces without any chemical reactions occurring.
No. Burning a log is a chemical change since the fire turns the wood into ash, water vapor, carbon dioxide, and elemental carbon.
