The pressure of the machine has to be reduced to 0.4 atm in order for the breathing machine to bring 500 ml of air into the lungs.
<h3>What is the relationship between volume and pressure?</h3>
Volume and pressure are inversely relate as given by the Boyle's law equation below:
The complete question is as follows:
<em>You Want To Design A Breathing Machine That Will Bring 500 ML Of Air Into The Lungs. You Begin With 100 ML Of Air At 2 atm Of Pressure. How Would You Change The Pressure In Your Machine To Accomplish Your Goal?</em>
From the question,
The change in pressure, will be:
Therefore, the pressure of the machine has to be reduced to 0.4 atm in order for the breathing machine to bring 500 ml of air into the lungs.

Answer:
At least 3 three extractions are required to recover at least 99.5 % of the material in the organic layer.
Explanation:
The partition coefficient of a solute (S) soluble in two immiscible solvents is given by the following formula
The lower layer is taken as an aqueous layer (1), while the upper layer is organic (2). The fraction of solute remaining in the aqueous layer is given by the following formula
Here, n denotes the number of extraction, and q^n represents the fraction of solute remaining in aqueous solvent after n number of extraction. According to the given data, the fraction of solute remaining in the aqueous layer after multiple extractions is 0.005, i.e., q^n=0.005. Mathematically,
Taking log on both sides
The above calculations show that the number of extractions should be greater than 2, i.e, at least 3, in order to achieve extraction greater than 99.5 %.
The correct answer is C. Colligative properties only depend upon the number of solute particles in a solution but not on the identity or nature of the solute and solvent particles. I hope this anwers your question.
Answer:
8.8 seconds
Explanation:
Formula: acceleration = (v - u) /t where v = final velocity, u = initial velocity and t = time
a = 2.5 m/s²
u = 5.0
v = 27. 0
t =?
at = v - u
t = (v - u) /a
= (27- 5)/ 2.5
= 8.8 s
