With a good mask-to-face seal and an oxygen flow rate of 15 L/min, the nonrebreathing mask is capable of delivering up to 90% inspired oxygen.
<h3>What is fraction of inspired oxygen?</h3>
FiO2 is the fraction of inspired oxygen which is explained as the concentration of oxygen inhaled by a person.
<h3>Non breather mask:</h3>
It delivers a high concentration of oxygen. Hence the liter flow will be 8-15L/min with the percentage of oxygen between 60-90%.
The liter flow of nonbreathing mask must not be less than 8L/min.
From the above information we can conclude that the fraction of inspired oxygen for a nonbreathing mask is 90%

A machine called a barometer is what is used to measure atmospheric pressure :D
Its A because there has to be a roman numeral to indicate which net charge of iron was used
Answer:
B- Iodine
Explanation:
Using the periodic trends, electronegativity (electron affinity) goes down as you go down a period. This is due to the atom gaining new shells when going down each period, resulting in a weakened attraction force between the nucleus and the electrons in the cloud. In other words. as more shells are added, the weaker the atom's affinity for electrons are and the less electronegative it is. As a result, Iodine would have the weakest attraction for electrons in a bond with Calcium as it is the furthest down in the periodic table.
