Video transcript

Hello everyone today. We are being given the falling problem. Consider the set of ions below identify the central atom and the number of electron domains for each can tie on or each an ion. So first it's important to note that electric or electron domains are simply lone pairs or Adams that are bonded to a central atom. So their lone pairs are atoms that are bonded to a central adam. So we'll label the 1st 11, the 2nd 12 and the 3rd 13 For number one. We see that the central atom here is carbon or a simple see And we see that it is connected to 123 chlorine and so therefore its electron domain is three for two. We see a central atom here is nitrogen and it has brought into 1234 methyl groups. So its electron domain is four. And last but not least we see we have a phosphorus here and it has bonded to 123456 bro means so its electron domain is six. And with that we have answered our question overall. I hope this helped until next time.

Textbook Question

Fluorocarbons (compounds that contain both carbon and fluorine) were, until recently, used as refrigerants. The compounds listed in the following table are all gases at 25 °C, and their solubilities in water at 25 °C and 1 atm fluorocarbon pressure are given as mass percentages. (c) Infants born with severe respiratory problems are sometimes given liquid ventilation: They breathe a liquid that can dissolve more oxygen than air can hold. One of these liquids is a fluorinated compound, CF3(CF2)7Br. The solubility of oxygen in this liquid is 66 mL O2 per 100 mL liquid. In contrast, air is 21% oxygen by volume. Calculate the moles of O2 present in an infant’s lungs (volume: 15 mL) if the infant takes a full breath of air compared to taking a full “breath” of a saturated solution of O2 in the fluorinated liquid. Assume a pressure of 1 atm in the lungs.
