Magnesium ignites at 632 degrees Celsius and burns at 1982 C. This is equivalent to igniting at 1169 degrees Fahrenheit and burning at 3599 F.
Magnesium emits ultraviolet light when burning, so one must not look directly at the flame. Magnesium is used in flares and tracer ammunition.
Fighting a magnesium fire is quite unusual. It actually burns better in carbon dioxide, so fire extinguishers can accelerate the fire, instead of extinguishing it. Adding water occasionally causes a steam explosion, which spreads the fire. Water can even split into hydrogen and oxygen in a magnesium fire, resulting in a hydrogen explosion.Learn More
A strong oxidizing agent strongly attracts electrons and gets reduced. An oxidizing agent is generally represented by halogens or a substance that consists of oxygen. It can readily give it away to another substance. The oxidation state of these substances decreases.Full Answer >
Nitrogen forms three covalent bonds. Nitrogen has five electrons in its bonding orbital, and it needs eight electrons to fill its outermost shell. Thus, nitrogen forms three covalent bonds and has one lone pair of electrons.Full Answer >
A mixture of water and starch is colloidal because it forms a shell of firmly bound molecules of water that stops the starch particles from aggregating with the molecules of water when they collide. However, when heated, aggregation occurs because the particles collide with each other with greater energy and this destroys the protective shell.Full Answer >
Wavelengths of spectra for Acetanilide ranges from 3300 cm-1 to 1700 cm-1. This is because of the bonds that are formed within the Acentanilide chemical structure.Full Answer >
