What element forms an ion with an electronic configuration of 1s2 2s2 2p6 (or [Ne]) and a -2 charge? Give the symbol for the element. Which of the following elements is least likely to form a cation that will form an ionic bond with an ion of a group 7A element? (a) Rb (b)...
(Garnet and peridot are both silicate gemstones, formed when crystals of silicon cool out of the magma that makes up our planet's interior. Peridot forms in the presence of divalent cations, things with a 2+ charge like calcium and magnesium, while garnet requires trivalent ions like aluminum...
1 seen through time, allowing the practitioner to track genealogical linkage between three related concurrent variants of θ (at time t1) and their ancestral θz (at a prior time t0, and which can or cannot be an element of α). The genealogical relationships between θ-theories can be ...
Another element in the SCD and CF responses about cau- sality is important to note. When asked to discuss genetic ver- sus nongenetic cause, these respondents emphasized the ben- efit of having had a genetic condition from birth and being allowed to adapt to it. They contrasted this ...
generally considered the first conducted in the context of trying to understand the origin of life. It is thus widely deemed to have opened the modern experimental period of research into the mechanism of the origin of life and to have been the first intentional example of “prebiotic chemistry...
-Organic salts have a reasonable solubility in many polar organic solvents,有机盐在许多极性有机溶剂中具有合理的溶解度 but are generally much more soluble in water than in these organic solvents. The non-organic counter cations are usually Na+, K+, or NH4+, all of which generally form solubl...
Displacement reactions are a type of chemical reaction in which one element or group is displaced from a chemical compound by an...
Very interesting read here...haven't heard anything about water vapour feedback yet. Enlighten me if what i say is wrong but are theIPCCmodels flawed in that their water vapour feedback element is missing out on a rather unavoidable factor in gravity. Douglas Hoyt discusses here http://www...
