This reaction can be called "deoxidation" or "reduction".
A reaction in which oxygen is removed from a compound is called a reduction reaction.
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.
One way to determine whether a gas given off during a chemical reaction is oxygen or hydrogen is by performing a gas test. For example, the gas test for oxygen involves relighting a glowing splint when inserted into the gas. If the splint reignites, then the gas is oxygen. The gas test for hydrogen involves holding a lit match near the gas, and if a "pop" sound is heard, then the gas is hydrogen.
An example of a chemical equation where both the reactant and product have an equal number of atoms of a given element is the reaction of hydrogen gas (H2) with oxygen gas (O2) to form water (H2O). In this reaction, two molecules of hydrogen gas combine with one molecule of oxygen gas to produce two molecules of water.
How could a chemist find out how much mass is given off as gas during a chemical reaction
A reaction in which oxygen is removed from a compound is called a reduction reaction.
Aerobic
The reaction of sulfur and oxygen to produce sulfur dioxide is called combination or synthesis.
Reduction reactions or deoxygenation reactions are processes in which oxygen is removed from a molecule or compound.

It is sign of chemical reaction because smell and heat is produced.
A reaction that emmits heat is called an exothermic reaction .

Tarnishing of metal is a chemical change because it involves a reaction between the metal and substances in the environment (such as oxygen or sulfur compounds) that forms a new compound on the surface of the metal, altering its properties.
It is Heat that is 'given off' by a chemical reaction.
a reactant
A reaction in which heat is given out.
