No, that would probably be considered a physical change. It is only a chemical reaction its chemical makeup is changed.

Why does burning a log in the fireplace involve a chemical reaction while sawing a log in half does not?
Because burning a log in a fireplace involves a chemical change and sawing a log in half only reguires a physical change.
Is matter being lost when burning a log?
In a chemical reaction the mass of reactants is equal to the mass of products; burning is a chemical reaction.
If the amount of oxygen reaching the log is reduced what happens to the rate of this chemical reaction?
the rate decreases
What is the name given to the chemical reaction that result in fire?
Fire(Burning) is a chemical change. Once you burn a log, you won't get the log back, that's how it's a chemical change. Also, Fire needs Oxygen (O2) to burn and stay alive but with too much Carbon Dioxide (CO2) it will die out.
What forms of energy is used as a log burns in a fireplace?
Burning or rapid oxidation is a chemical reaction which releases heat.
Is sawing a board in half is a chemical change or a physical change?
Physical
How does one win a sawing contest?
Sawing contests usually consist of three stages: Chopping, hand sawing, and chainsawing. You start on the competition by chopping a log in half, any way you can, you then go to a manual saw, doing the same, then you go to the chainsaw. The person who finishes first wins.
Which process is an example of a chemical change?
A process in which the reactants form products with different chemical compositions is generally a chemical change. It is also often harder to change the products of a chemical reaction back into the reactants, than it is for a physical change. For instance, burning a log would be a chemical change; you don't have wood after you burn the log, you have carbon dioxide, soot, etc., and you can't get the wood back by reversing the process.
What causes atom to react with each other?
A chemical reaction
When a log burns is it a physical or chemical change?
It is a chemical change. A physical change to the log would be, for example, cutting the log in two. When it burns, it turns into CO2 and H2O, so it can't be turned back into a log.
What chemical is formed in a chemical reaction?
The chemical or chemicals formed in a chemical reaction are called the product of the chemical reaction.
Is an icy hot a chemical reaction or a physical reaction?
Its a chemical reaction.
