Carbon disulfide (also spelled as carbon disulphide) is an inorganic compound with the chemical formula CS 2 and structure S=C=S.It is also considered as the anhydride of thiocarbonic acid. [8]
Biology is the overall natural science that studies life, with the other life sciences as its sub-disciplines. Some life sciences focus on a specific type of organism. For example, zoology is the study of animals, while botany is the study of plants. Other life sciences focus on aspects common to all or many life forms, such as anatomy and ...
The life of such a system is limited, as the entropy of a closed system can only increase with time. But if the otherwise closed system is allowed to accept high-temperature radiant energy from an external source (e.g., sunlight) and to reject low-temperature waste heat to deep space, it can continue indefinitely.
Skylab 3 (also SL-3 and SLM-2 [2]) was the second crewed mission to the first American space station, Skylab.The mission began on July 28, 1973, with the launch of NASA astronauts Alan Bean, Owen Garriott, and Jack Lousma in the Apollo command and service module on the Saturn IB rocket, and lasted 59 days, 11 hours and 9 minutes.

A column of porous black graphite formed during the experiment. Carbon snake experiment. The carbon snake is a demonstration of the dehydration reaction of sugar by concentrated sulfuric acid. With concentrated sulfuric acid, granulated table sugar performs a degradation reaction which changes its form to a black solid-liquid mixture. [1]
These results call for a re-examination of many ancient real-world examples to see if they are more likely to be fossils or non-biological mineral deposits." [ 11 ] [ 12 ] One use of the study of chemical gardening is to be better able to distinguish biological structures, including fossils , from non-biological structures on the planet Mars .
STS-40, the eleventh launch of Space Shuttle Columbia, was a nine-day mission in June 1991.It carried the Spacelab module for Spacelab Life Sciences 1 (SLS-1), the fifth Spacelab mission and the first dedicated solely to biology.
CCS can be a ligand. It can form an asymmetrical bridge between two molybdenum atoms in Mo2(μ,σ(C):η 2 (C′S)-CCS)(CO) 4 (hydrotris(3,5-dimethylpyrazol-1-yl)borate) 2 In this one carbon atom has a triple bond to a molybdenum and the other has a double bond to the other molybdenum atom, which also has a single bond to the sulfur atom.
