Formaldehyde

FORMALDEHYDE By: Zach Ross .

=//Properties //= Formula: CH2O Molar Mass: 30.026 g/mol IUPAC: methanal Melting Point: -92 degrees C Boiling Point: -21 degrees C Density: 812.14 kg per cubic meter =//Appearance //= Colorless Gas == =// 3D Model //=

== == = //Historical Background// = The compound was founded by German chemist August Wilhelm Von Hofmann. However, it was first stumbled upon accidentally by a Russin chemist by the name of Aleksandr Butlerov. A.W. Hofmann officially identified it to the world in 1868.

= //Found and Obtained// = It is the simplest aldehyde. It exists in many different thing. It is found in water as a hydrate H2C(OH)2. It is obtained in forest fires, car exhaust, and in cigarette smoke. If a connection between sunlight and oxygen is produced, it will create smog from which formaldehyde is made.

= //**Uses and Importance**// = Formaldehyde is found inside glues, preservatives, antiseptics, paints, and film processers. It can be made through a fuel burning stove. Formaldehyde is put in human and animal remains to preserve the bodies.

= //[|World Occurrences]// = During Hurricane Katrina and Rita, FEMA sent out hundreds of trailers for victims to use as shelter. However, excessive amounts of formaldehyde was found in the trailers. It caused extreme headaches to those who were used them. In addition, it made it hard to breathe for the victims. The trailers were also used in the Iowa floods of 2008. In Vietnam and Indonesia, Formaldehyde was found in food.

= //Chemical Properties// = Formaldehyde is the simplest aldehyde so it has the same reactions as most aldehyde. Although, it is more reactant than any other aldehydes. When combined with hydrogen sulfide trithiane. Also, it could be made when methane is oxidated.

=// Percent Composition //= Carbon: 40% Hydrogen: 6.73% Oxygen: 53.27% Carbon: 27.72 % (3.33 mol) Hydrogen: 33.33 % (6.73 mol) Oxygen: 20.8% (3.33 mol) : Carbon is connected by a single bond to Hydrogen on the left and right and it is double bonded to Oxygen.
