Yes- fire is an example of combustion- the reaction with oxygen to produce a variety of products which depend on the material being burnt- burning say coal or oil gives CO2 and CO as well as many other compounds. Yes it is. When you set something on fire, it means you are oxidizing it.

∙ 15y agoI believe it's combustion (its been a while since classes). Fire needs 3 things to survive, called the fire triangle. They are oxygen, heat and fuel. You add the 4th element (spark) and you get combustion.

∙ 14y agoFire is classified as a combustion reaction in chemistry. More generally, it is an oxidation-reduction reaction. It is classified as such because the oxidation states of the materials involved change during the reaction. Carbon is oxidized and oxygen is reduced.

Why do you have to balance chemical equations?
You only need to balance a chemical equation if you want to know the proportions (how many of each type of molecules participate in the reaction).You only need to balance a chemical equation if you want to know the proportions (how many of each type of molecules participate in the reaction).You only need to balance a chemical equation if you want to know the proportions (how many of each type of molecules participate in the reaction).You only need to balance a chemical equation if you want to know the proportions (how many of each type of molecules participate in the reaction).

An amtom undergoes a reaction ant attains a more stable from how do you know is it was chemical or nuclear reaction?
If an atom undergoes a reaction and attains a more stable form, you know if the reaction was a chemical reaction or a nuclear reaction by studying what exactly happened to the atom.
Is picking up iron filings with a magnet a chemical reaction?
No, a chemical reaction is when the atoms are not mixed together but chemical bonded together. You know when a chemical reaction has happened when you can smell, hear or see things reacting.
