Answer: 50 to 80mmHg
Explanation:
Retinopathy of prematurity (ROP) is described as an ocular condition associated with O2 administration to premature infants. Excessive blood O2 levels produce retinal vasoconstriction, which (if prolonged) can result in permanent blindness. This risk poses a serious management problem, for the premature infant is often in need of supplemental O2. The American Academy of Pediatrics has recommended that keeping PaO2s between 50 to 80mmHg is the best way to minimize the risk of Retinopathy of Prematurity.
amount of electrons on their outer shell: 1 electron.
Answer:
Linoleic acid has 18 carbons in its carbon chain and 2 double bonds, and the first double bond starts at the 6th carbon from the omega end, thus, it is named omega 6.
Explanation:
Fatty acids are carboxilic acids with long chains of carbon (always in even numbers). There are two types of fatty acids: saturated fatty acid s(without double bonds) or unsaturated fatty acids (with double bonds). Unsaturated fatty acids has common names (linolenic acid, palmitic acid, etc.) and the position of the first double bond present in the molecule are indicated with the greek letter omega (counting from the omega extreme, it means the one with metyl radical) . Based 0on that, unsaturated fatty acids are also called omega x, where "x" represents the position of the first double bond. In the present case, the fatty acid that has 18 carbons and two double bonds is commonly named as linoleic acid and taken into account the position of its first double bond (carbon 6) it is also called omega 6.

See explanation
Explanation:
All molecules possess the London dispersion forces. However London dispersion forces is the only kind of intermolecular interaction that exists in nonpolar substances.
So, the only kind of intermolecular interaction that exists in dimethyl ether is London dispersion forces.
As for ethyl alcohol, the molecule is polar due to the presence of polar O-H bond. In addition to London dispersion forces, dipole-dipole interactions and specifically hydrogen bonding also occurs between the molecules.
Because ethyl alcohol is polar, it is more soluble in water than dimethyl ether.
Answer:
Ionic Substance is....
Explanation:
In chemistry, an ionic compound is a chemical compound composed of ions held together by electrostatic forces termed ionic bonding. The compound is neutral overall, but consists of positively charged ions called cations and negatively charged ions called anions.
