Ethylene (IUPAC name: ethene) is a hydrocarbon which has the formula C 2 H 4 or H 2 C=CH 2.It is a colourless, flammable gas with a faint "sweet and musky" odour when pure. [7] It is the simplest alkene (a hydrocarbon with carbon–carbon double bonds).
Although ignitable liquids are the most common fire accelerants, other chemicals such as propane or natural gas could also be used to accelerate a fire. Detecting the use of a fire accelerant at a crime scene can be the difference between classifying a fire as accidental or as an arson. Once a case is determined to be an arson, the detection of ...
Firefighters worked to contain the fire so it would burn out as quickly as possible, and now there are few active flames and very little release of combustion byproducts, according to Mendoza.
Reports that artefacts were removed from the wreck of La Girona and HMS Drake are being investigated.
The components of long-term fire retardants are mainly salts – typically agricultural fertilizers – that "alter the way the fire burns, decreases the fire intensity, and slows the advance of ...
