The central atom in BrF5 has how many bonding pairs of electrons and how many non-bonding pairs of electrons? How many valence shell electrons does the element carbon have? Which atom is most likely to form a polar covalent bond with carbon?
Ambient light - Ambient light is light that has bounced and scattered in many directions so that it is does not seem to have a specific source. A good example of ambient light is the glow in the sky around a major city. It would be very hard to identify a single source of light for...

They each have 7 electrons in their outer shell; in each case, 2 are in an s orbital and 5 are in p orbitals. Notice that because the 3 elements all are in the same column of the periodic table, they have the same number of valence electrons. 6. The atomic number...
How many atoms of magnesium are in a sample of 4 moles? Iron oxide is produced when iron metal is exposed to air, via this process: 3O_2 + 4Fe \rightarrow 2Fe_2O_3 a) Which ion or atom is reduced? b) Which ion or atom is oxidized? c) How many electrons are transferre...
For a surface colony, there are also many challenges. The long lunar nights (354 hours long) would means that reliance on solar power would be impeded in any location other than the polar regions. In addition, the significant variations in temperature would be something colonies would have to...
When you connect a battery's two electrodes into a circuit (for example, when you put one in a flashlight), the electrolyte starts buzzing with activity. Slowly, the chemicals inside it are converted into other substances.Ions(atoms with too few or too many electrons) are formed from the ...
Furthermore, many of these core metabolic proteins are also essential for cellular viability and have therefore been sufficiently conserved to enable the implementation of tractable paleogenetic studies. Ancestral sequence reconstruction has also become desirable for deep time biogeochemical studies because, ...
Venus does have a tiny quasi-moon named Zoozve, which occupies a strange orbit around Venus and the sun. 15. Mimas NASA "That's no moon!" Obi-Wan Kenobi was right about the Death Star. This celestial object, however, is a moon. Mimas, one of Saturn’s many moons, is best known...
