Answer:
0.1935atm is the pressure of the gas.
Explanation:
In the problem you have the mass of Neon (You can obtain moles using molar mass), you have volume, and temperature. You can use general ideal gas law to solve pressure:
PV = nRT
P = nRT / V
<em>Where P is pressure in atm, n are moles, R is gas constant (0.082atmL/molK), T is absolute temperature (20.0°C + 273.15 = 293.15K), and V is volume in L = Volume in dm³</em>
<em />
<em>Moles gas:</em>
Molar mass Ne = 20.1797g/mol
0.325g * (1mol / 20.1797g) = 0.0161 moles
Replacing:
P = nRT / V
P = 0.0161 moles * 0.082atmL/molK * 293.15K / 2L
P = 0.1935atm is the pressure of the gas
Answer:
Evaporation
Explanation:
Boiling the water will make it evaporate, leaving the solid at the bottom of the solution
If you do not this, I suggest brushing up on delocalization as well as sigma/pi bonds. Benzene is the only one of the 5 with any pi bonds, so this should be a relatively easy question if you are familiar with the concepts. I would search up a detailed (not to detailed though) explanation of both.
Explanation:
What type of graph is most appropriate to present the data in Table 4? Create a graph of the data in Excel or another graphing software and submit it to your instructor.
Develop a detailed hypothesis for your experiment.What would your experimental approach be to test this hypothesis? Be detailed in your description of the experiment.
6.What are the independent, dependent, and controlled variables in your experiment?
What type of graph would be appropriate for this data set? Why?
Simple molecules have no overall charge, or charged particles that can separate, so simple molecular substances cannot conduct electricity, even when liquid or dissolved in water.
