but because the effluent from the factory, once the bottom stream become colorful; Forest, once very lush, but due to the deforestation of people, make once lush forest into a desolate desert...
Both elements have multiple oxidation states, but the same biological pathway does not reach some of these states. For instance, elemental sulfur (S0) can be formed by (partial) sulfide bio-oxidation but not by sulfate bio-reduction, whereas elemental selenium (Se0) can be formed by selenite...
What will most likely occur if sulfur forms an ionic bond with another element? How does the hydronium ion form? How does a cation differ from an anion? What are ions and how do they form? How do polyatomic ions behave in an ionic compound?
The other part of a typical solar cell is doped with the element boron, which has only three electrons in its outer shell instead of four, to become P-type silicon. Instead of having free electrons, P-type ("p" for positive) has free openings and carries the opposite (positive) charge....
The larger the volume of the developer, the greater the amount of sulfur is removed from the hair. Loss of sulfur causes hair to harden and lose weight. This is why, for the majority of hair coloring, the developer is maintained at 30% volume or less. Ammonia -- This alkaline allows ...
An effectivealternative to the photovoltaic systemis known as the concentrated solar plant. This method does away with silicon panels and instead uses a massive array of polished mirrors to capture sunlight. These mirrors are programmed to follow the sun's movement anddirect the light to a large...
What happens to the valence electrons in an ionic bond? What does ionic bonding have to do with chemical reactions? Why can transition metals form bonds with more than one ion? How can one tell what bonds have been broken and what bonds have been formed from a chemical reaction?
How many unpaired electrons are in a cu2+ ion? Electron Pairing Atoms and ions consist of electrons that occupy orbitals somewhere around the nucleus of the atom. Orbitals are spaces around the nucleus that an electron has the greatest likelihood of occupying. Different orbitals have different ene...
How many valence electrons are in an atom of sulfur? a. 16 b. 6 c. 5 d. 2 How many electrons does a CO atom have in its 3-d subshell? How many valence electrons are there in an atom with the electron configuration (noble gas)ns2(n - 1)d10np3?
What does K equal in Avogadro's law? Given the number of moles, find the actual count of atoms, ions, or molecules. Be sure to show units that include atom, ion, or molecule. 2.45 moles of Ca(NO3)2 Given a sample of Glucose C6H12O6 how many hydrog...
