* Nickel (Ni), a major component of nichrome, reacts with oxygen to form nickel oxide (NiO), a green-colored compound.
* Chromium (Cr), the other major component, reacts with oxygen to form chromium oxide (Cr2O3), a green-colored compound as well.
Therefore, the primary products of burning nichrome in air are nickel oxide (NiO) and chromium oxide (Cr2O3).
These oxides form a thin layer on the surface of the nichrome wire, which can affect its electrical resistance and melting point.
It's important to note that burning nichrome wire produces some heat and light, just like any other combustion process. However, the amount of heat and light produced is relatively small compared to other fuels.
Additionally, burning nichrome wire can also release small amounts of nickel and chromium particles into the air, which can be harmful if inhaled. Therefore, it's important to use proper ventilation when working with heated nichrome wire.
