I don’t get it. What is the question asking?
The temperature of the gas sample is 813 K.
<u>Explanation:</u>
We have to use the ideal gas equation to find the temperature of the gas sample.
The ideal gas equation is PV = nRT
Pressure, P = 429 mm Hg = 0.56 atm
Volume, V = 560 mL = 0.56 L
R = gas constant = 0.08205 L atm mol⁻¹K⁻¹
Mass = 0.211 g
Molar mass of carbon di oxide = 44.01 g / mol
Moles, n = 
= 0.0047 mol
Now, we have to plugin the above values in the above equation, we will get the temperature as,
T = 
= 813 K
So the temperature of the gas sample is 813 K.
Answer:
C)
Explanation:
(A) Cover the chamber. => <u>It helps to keep the solvent in his gas state</u>
<u />
(B) Gently swirl the solvent in the chamber prior to placing the TLC plate inside => <u>The mechanical energy can promote the conversion from the liquid state to the gas state and help to the saturation process.</u>
<u></u>
(C) Add ninhydrin (a visualization technique) to the developing solvent =><u>There is no change in the saturation process</u>
(D) Place a paper wick (like a piece of filter paper) inside the chamber=><u>Increases the area for evaporation. The solvent can go up across the paper by capillarity a then can be evaporated increasing the saturation in the chamber.</u>
-3
explanation: if you subtract 5 from 8 you get 3 just put a negative sign and you have your answer :)
Predation, because the pitcher plant is preying on the insects.
