Baryon (4/13)



  1. How would I show the rules that were applied for naming cations and anions that helped me to determine the name?
  2. Yes, I’m aware. I couldn’t find anything in my reference book so I was trying to find a better explanation online. Phosphorus pentachloride (PCI5) is an exception to the octet rule because it has more than 8 electrons around the valence shell. Phosphorus (PCI5) can form an expanded octet containing ten electrons. The central phosphorus atom is bonded to five chlorine atoms. While PCI3 contains a phosphorus atom with an octet. How is this?
  3. n order for the P atom to form bonds with 5 Cl atoms, it must have an expanded octet.
  4. Phosphorus pentachloride (PCI5) is an exception to the octet rule because it has more than 8 electrons around the valence shell. The chlorine atoms (PCI3) obey the octet rule because the atom has five electrons and need three to fulfill its octet, while the phosphorus atom does not. Phosphorus (PCI5) can form an expanded octet containing ten electrons in the 3d orbitals. is this correct?
  5. Transition metals Fe2+ has the lower state than oxygen (Fe3+ has the higher state), so “Fe” becomes ferrous. The name of Fe2+O can also be written as ferrous oxide. The terms “ferric” and “ferrous” are both use to refer to ions containing iron, since iron’s symbol is “Fe.” Ferrous = iron(II) Ferric = iron(III) Oxide = O-2 Anions always take the –ide suffix. Can i leave this?
  6. Equation is not simplified. It should be Zn + 2HCl —> ZnCl2 + H2 How do do I explain what is wrong with this equation?
  7. I have to show my work for this question and I’m not sure if this is the correct way to do it H2(g) + CI2(g) —> 2HCI(g) The balanced equation is H2 + CI2 —> 2HCI There are two hydrogen (H) atoms on the reactants side and two chlorine (CI) atoms on the reactants side. Two hydrogen (H) atoms and two chlorine (CI) atoms are produced. To balance them, we put a coefficient of 2 in front of the product hydrogen chloride (HCI).
  8. I don’t really know how to do the calculations (for showing my work.)
  9. Okay got it, but is there a better way that I can show how the name is determined?
  10. I’m suppose to give how I determined the name though..
  11. I looked this up. I’m suppose to explain how I determined that is the correct name but I was struggling trying to come up with an explanation. Ferrous = iron(II) Ferric = iron(III) Here is the example in my book.
  12. Yes, this is part of my studies. I’m following the example in my book but I need to show my work along with it so I was having trouble with that. I wasn’t sure if my explanation was correct.
  13. Can you please give me a hint to what kind of explanation it should be? are you referring to electron configuration?
  14. two Fe atoms have an oxidation state of +3? I’m not sure how else to explain it?
