Is a burning log a mixture?
A log is a mixture regardless of whether it is burning.
Why does burning a log in the fireplace involve a chemical reaction while sawing a log in half does not?
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.
Is burning a log a example of chemical or physical changes?
Although it has physical consequences, burning a log is a chemical change. The molecules of the log react with oxygen to form carbon dioxide, water steam, and many other products. A simple, fairly reliable test to tell the difference between physical and chemical changes is: Can the process be reversed rather easily? If the answer is yes, like dissolving salt in water, it is a physical change; if no, a chemical change.
Is burning a fire a physical or chemical change?
Burning is a chemical change.
Is cutting a stack of wood from a log a chemical change?
No, it is a physical change. If you think about cutting the wood, the pieces will be smaller than the log, but they will have all of the same properties as they did when they were put together. An example of a chemical change is burning the wood. The act of burning it would be a chemical change since it is converting the wood into carbon and water vapor.
Is a burning log a mixture?
A log is a mixture regardless of whether it is burning.
Which is not a physical change hitting a log with an axe cutting a log burning a log or hammering a spike through a log?
Burning the log is a chemical change. All of the others are physical changes.

Is burning a fire a physical or chemical change?
Burning is a chemical change.
Is burning a log a mixture?
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.
How do you know a chemical change takes place when a log burns?
Burning is a chemical process: the nature of the initial material is changed.
Is cutting a stack of wood from a log a chemical change?
No, it is a physical change. If you think about cutting the wood, the pieces will be smaller than the log, but they will have all of the same properties as they did when they were put together. An example of a chemical change is burning the wood. The act of burning it would be a chemical change since it is converting the wood into carbon and water vapor.
Is burning logs a physical change?
No. Burning a log is a chemical change since the fire turns the wood into ash, water vapor, carbon dioxide, and elemental carbon.
Is burning chemical change or physical change?
Burning is a chemical change.
Is a log burning a chemical or physical change?
Chemical change, because it is irreversible. The chemical composition of the substance actually changes. A physical change is a change of state, like water to ice. There, H20 is still H20.
What is the observable change of burning a log?
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.
