B. The time is likely between 40 - 80 seconds.
<u>Explanation:</u>
One group of students were asked to leave a whole mint in their mouth, not moving it around, and let it dissolve, which takes very long time to dissolve since there is lower frequency of collision among the saliva particles and mint.
Another group swirled a whole mint around in their mouths, so the frequency of collision between the saliva and the mint particles increases, there by increase in dissolving capacity, but the timing will be lesser when compared to other groups used mints broken into smaller pieces.
So the time for swirling is likely between 40 - 80 seconds.
Answer: 36.6°C
Explanation:
Given that,
initial pressure of helium (P1) = 1.20 atm
Initial temperature (T1) = 22.0°C
Final temperature (T2) = ?
Final pressure of helium (P2) = 2.00 atm
Since pressure and temperature are given while volume is constant, apply the formula for pressure's law
P1/T1= P2/T2
1.20 atm / 22.0°C = 2.00 atm / T2
Cross multiply
1.20 atm•T2= 2.00 atm•22°C
1.20 atm•T2= 44 atm•°C
Divide both sides by 1.20 atm
1.20 atm•T2/1.20 atm = 44 atm•°C/1.20 atm
T2 = 36.6°C
The correct answer for the given statement above would be TRUE. It is true that chromatography separates gas or liquid solutions using a stationary phase. Chromatography is the separation of mixture <span>that distributes components to separate between two phases which includes stationary phase and the other is mobile phase.
