The distribution of electrons across the shells of sulphur (atomic number = 16) is as follows (number of shells indicated with Roman numbers: number of electrons shown with Arabic numbers) (1-8; 11 - 8 (1 - 2; || - 4; ||| - 4 (1 - 4; || - 4; III - 8 1-2; 11-6; III - 8 (1-2; 11 - 8; III - 6

I was at the supermarket the other day shopping for groceries, and I picked up a box of Schtuck Margarine. On the front of the box, it listed “5% trans fats” and on the ingredient list it had “hydrogenated corn oil” listed as the main ingredient. If corn oil is a polyunsaturated vegetable oil with cis- double bonds (only), why is it hydrogenated, and where are the trans fats coming from? Additionally, what is the issue with trans- fats?

Answer the following questions about compound A, represented in the given ball-and-stick model. In a ball-and-stick model, each black sphere represents a carbon atom and each white sphere represents a hydrogen atom. Part: 0 / 4 Part 1 of 4 Give the IUPAC name for compound A. ☑

Atoms A and B interact to form a compound, AB2. When measured, atom A has a partial negative charge and atom B has a partial positive charge. From this information, we can conclude what? Select only ONE answer choice. Note: - means "approximately equal to" , A > B means "A is greater than B" , and A B: AB2 is hydrophilic Not enough information to answer the question

The triple point of an element is at 75 torr and 125°C. This means that liquid is more dense than solid cannot exist at 1 atmosphere pressure cannot have a vapor pressure less than 75 torr cannot exist above 125 degrees Celsius What is the electron geometry (or electron arrangement) around an atom in a molecule or ion which is surrounded by three lone pairs of electrons and two single bonds T-shaped see-saw trigonal planar trigonal bipyramidal linear A red blood cell placed in pure water will swell because water moves from a higer osmotic pressure to a lower osmotic pressure the osmotic pressure is greater in the cell than in the water the osmotic pressure is the same in the cell and the water the somotic pressure is greater in the water than in the cell

Unshared, or lone, electron pairs play an important role in determining the chemical and physical properties of organic compounds. Thus, it is important to know which atoms carry unshared pairs. Use the structural formulas below to determine the number of unshared pairs at each designated atom. Be sure your answers are consistent with the formal charges on the formulas. H₂C H₂ b Hc N CH2 The number of unshared pairs at atom a is The number of unshared pairs at atom b is The number of unshared pairs at atom c is The number of unshared pairs at atom a is 1 v The number of unshared pairs at atom b is Ov The number of unshared pairs at atom c is 1.

The naturally-occurring amino acid L-serine (NH2-CH(COOH)-CH2-OH, dry form) shares all of the following features with the naturally-occurring amino acid D-serine, except: the same three-dimensional arrangement of covalent bonds the same stoichiometry the same number of covalent bonds the exact same atoms the same number of atoms

In the following questions, consider the carbanion formed by the arrow pushing below: он | HC-C-R H ཋཙམཏིཏཡརིཡཐཱ པཱལཾ ཏིཡཏིཡ, B: H C-C-R Н Question 7 2 pts Below are a proposed resonance structure of the carbanion and rules of resonance. Which rules, if any, does the resonance structure break? (Select all that apply.) Ο Η | │ C-C-R H The formal charge of the molecule cannot change. ☐ Single (sigma) bonds cannot be broken. With the exception of carbocations, octet rules must be satisfied. ☐ All of the above rules are satisfied.
