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%

Answer:
We know that an antacid is a base that can neutralize the stomach acid when ingested. The student observed that a soluble antacid tablet reacted faster in relieving pain due to the excess acid secreted in the stomach. So, the problem that can be studied is the effect of temperature on the rate of neutralization of stomach acid by the antacid. The independent variable is the one the student is going to vary that is the temperature. The dependent variable is the rate of reaction or the time taken for an antacid tablet to neutralize the acid present in stomach. The controlled variable is the tablet taken, that is the student should use a specific antacid tablet to ensure that the rate of reaction or the time taken for the antacid tablet to neutralize the acid present in stomach is not affected by the chemical composition of tablet.
