Today I will explain what a valence electron is and how many valence electrons each of the atoms your asking about have. :)
→ A valence electron is an electron in the outer shell of an atom that is able to participate in bonding. While iodine has 53 electrons, all but seven are in the inner shells of the iodine atom.
→ Sulfur has sixteen electrons in total, two in the inner shell, eight in the middle, and six in the outer. This means that sulfur has six valence electrons.

After the addition of 6.47 mL of 0.303 M HCl. Solution :- lets first calculate the moles of the NaOCl and HCl Moles = molarity *volume in liter Moles of NaOCl = 0.100 mol per L * 0.053 L =0.0053 mol Moles of HCl =0.303 mol per L *0.00647L=0.00196
p =
<em>p equals m over V</em>

Answer:
From what I personally know, Acenaphthylene 75%. Empirical Formula (Hill Notation): C12H8. CAS Number: 208-96-8. Molecular Weight: 152.19. Beilstein: 774092. EC Number:
Explanation:
Acenaphthylene, a polycyclic aromatic hydrocarbon is an ortho- and peri-fused tricyclic hydrocarbon. The molecule resembles naphthalene with positions 1 and 8 connected by a -CH=CH- unit. It is a yellow solid. Unlike many polycyclic aromatic hydrocarbons, it has no fluorescence. Acenaphthylene/Formula is C12H8.
I'm not sure if this will help you but this is what I know so I hope it does :)
