The exoplanet Kb has been all over the news lately, with provocative headlines suggesting a life detection because of the possible presence of dimethyl sulfide DMS , a molecule produced by life on our own planet. Almost nine times as massive as Earth, Kb is certainly noteworthy, but just how likely are these speculations? Centauri Dreams regular Dave Moore has some thoughts on the matter, and as he has done before in deeply researched articles here, he now zeroes in on the evidence and the limitations of the analysis. This is one exoplanet that turns out to be provocative in a number of ways, some of which will move the search for life forward. Two planets are known to orbit this star: Kc, a 5. The latter planet transits its primary, so from its mass and size 2.

In a Hydrogen dominated atmosphere, Hydrogen combines with Oxygen and Carbon.

Thus far, we have used two-dimensional Lewis structures to represent molecules. A bond angle is the angle between any two bonds that include a common atom, usually measured in degrees. A bond distance or bond length is the distance between the nuclei of two bonded atoms along the straight line joining the nuclei. Valence shell electron-pair repulsion theory VSEPR theory enables us to predict the molecular structure, including approximate bond angles around a central atom, of a molecule from an examination of the number of bonds and lone electron pairs in its Lewis structure. The VSEPR model assumes that electron pairs in the valence shell of a central atom will adopt an arrangement that minimizes repulsions between these electron pairs by maximizing the distance between them. The electrons in the valence shell of a central atom form either bonding pairs of electrons, located primarily between bonded atoms, or lone pairs. The electrostatic repulsion of these electrons is reduced when the various regions of high electron density assume positions as far from each other as possible.

Formaldehyde is one of the simpler naturally occurring aldehydes. It is generally in a gaseous state with a strong, pungent smell. When used in an aqueous state as formalin, this compound can be used to produce and synthesize several compounds in industries. Due to its properties, this is also used as a disinfectant and has also been used to preserve the tissues of the specimens. This colorless- gas compound has several uses, and thus it becomes vital to know its physical and chemical properties. To know all this, one needs to know the molecular geometry of the compound and its polarity. To understand the molecular geometry, shape, and polarity of CH 2 O , let us first quickly go through its Lewis Structure and hybridization. In the Lewis structure of Formaldehyde , the central Carbon atom has single bonds with two hydrogen atoms and a double bond with the Oxygen atom. There are no lone pairs of electrons on the central atom, while there are two lone pairs on the Oxygen atom. It becomes easy to study the molecular geometry of any compound once we know the Lewis structure and its hybridization.

Perhaps the water was uv photo disassociated into hydrogen which filled the atmosphere and the oxygen combined with other elements to form oxide compounds. OBJ Madhusudhan in his interview suggests that the spectra was a shot of the high-dry stratosphere. The other diagram tracks the condensation histories of various nebula dust types as they cool. A long form of the policy can be viewed on the Administrative page. It looks like both reactions should occur spontaneously, at least under standard conditions. Madhusudhan, M. To test my assumption, I did a rough back of the envelope calculation using online calculators, and looked at the wet adiabatic lapse rate the rate of increase in temperature when saturated air is compressed per atm. The presence of O 3 can function as a stand-in for O 2 , but molecules such as H 2 , N 2 , with no permanent dipole moment, are much harder to detect. Constantinou, M Holmberg, A. Medicine Thematic 3D Icon Set.

One of the first molecules used for studying and understanding molecular geometry and the basics of the Lewis structure is CH 2 O.

Prosty Zwroty. It could be life… But it could just be some hot internal layers of the atmosphere. Nixon, L. Telefon nadzorczy:. So when considering Sulfur in the equation, in a Type C atmosphere, it will be preferentially combined with Carbon as much as possible. Constantinou, M Holmberg, A. Two planets are known to orbit this star: Kc, a 5. So to arrive at this state, this planet must never have had much gas accretion in the first place, or lost large amounts of Hydrogen after it formed. Centauri Dreams is emphatically not a soapbox for political or religious views submitted by individuals or organizations. Another really interesting post and I did enjoy your previous one too, do you have any more diagrams of this Planet?
