Molecular weights of the species in the representative octane combustion are 114, 32, 44, and 18 for C 8 H 18, O 2, CO 2, and H 2 O, respectively; therefore one kilogram (2.2 lb) of fuel reacts with 3.51 kilograms (7.7 lb) of oxygen to produce 3.09 kilograms (6.8 lb) of carbon dioxide and 1.42 kilograms (3.1 lb) of water.
Hydrogen cyanide (formerly known as prussic acid) is a chemical compound with the formula HCN and structural formula H−C≡N.It is a highly toxic and flammable liquid that boils slightly above room temperature, at 25.6 °C (78.1 °F).
1,3,5-Trioxane, with the formula (CH 2 O) 3. It is a white solid that dissolves without degradation in organic solvents. It is a trimer of molecular formaldehyde. Paraformaldehyde, with the formula HO(CH 2 O) n H. It is a white solid that is insoluble in most solvents. Methanediol, with the formula CH 2 (OH) 2.
The body produces approximately 2.3 pounds (1.0 kg) of carbon dioxide per day per person, [72] containing 0.63 pounds (290 g) of carbon. In humans, this carbon dioxide is carried through the venous system and is breathed out through the lungs, resulting in lower concentrations in the arteries .
Propylene, also known as propene, is an unsaturated organic compound with the chemical formula CH 3 CH=CH 2. It has one double bond, and is the second simplest member of the alkene class of hydrocarbons. It is a colorless gas with a faint petroleum-like odor. [4]
Estimates of world population by their nature are an aspect of modernity, possible only since the Age of Discovery.Early estimates for the population of the world [10] date to the 17th century: William Petty, in 1682, estimated the world population at 320 million (current estimates ranging close to twice this number); by the late 18th century, estimates ranged close to one billion (consistent ...
Two 2.5" external USB hard drives Seagate Hard Drive with a controller board to convert SATA to USB, FireWire, and eSATA Current external hard disk drives typically connect via USB-C; earlier models use USB-B (sometimes with using of a pair of ports for better bandwidth) or (rarely) eSATA connection. Variants using USB 2.0 interface generally ...
