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.
Answer:
The formal charge on N is usually -1 for an anion, 0 for a neutral compound, and +1 in cations.

Answer:
XeF₂
Explanation:
Let's call the compound as XeaFb, where a and b are the number of atoms of each element. In the beginning, the partial pressure of XeaFb was 16 torr. By Dalton's Law, the total pressure of a gas mixture is the sum of the partial pressures of the components, so:
pH₂ = 64 - 16 = 48 torr
The reaction that happened was:
XeaFb + (b/2)H₂ → aXe + bHF
The stoichiometry of the reaction is 1:b/2:a:b. If all the XeaFb reacts:
1 torr of XeaFb -------- b/2 torr of H₂
16 torr -------- x
By a simple direct three rule:
x = 16b/2 = 8b torr of H₂ reacts
1 torr of XeaFb -------- a torr of Xe
16 torr -------- x
x = 16a torr of Xe is formed
Thus, 8b + 16a = 32
b + 2a = 4
The empirical formula is the minimum integer number of the elements in the compound. So, let's suppose a = 1 because fluorine can do only one bond, thus it's unprovable that will be more than one Xe bonded with one F:
b + 2*1 = 4
b = 2
Thus, the empirical formula is XeF₂.
