Answer:
157.29 Torr
Explanation:
This question may be solved by the mole fraction.
Mole fraction → Moles of gas / Total moles = Partial pressure of gas / Total pressure
If the atmosphere is about 21% you assume that the mole fraction is 0.21 so:
0.21 = Partial pressure of gas / Total pressure
0.21 = Partial pressure of gas / 749 Torr
Partial pressure of the gas = 749 Torr . 0.21 → 157.29 Torr

Answer:
We deduce that the correct option is option c: critical period
Explanation:
Hello!
Let's solve this!
The imprint is the learning that occurs in early ages, the example of the duckling is used, which follows anyone in early periods.
This is called the critical period.
We deduce that the correct option is option c: critical period
