Answer:
Explanation:The buffer is a mixture of ammonia (NH3) and ammonium (NH4+). ... Since ammonia (NH3) is a weak base, it will have a pH above 7 and since ammonium (NH4+) is a weak acid, it will have a pH below 7. Ammonia (NH3) is a weak base and ammonium (NH4+) is a weak acid. Ammonia (NH3) is the conjugate base of ammonium (NH4+).
Answer: Temperature will Increase
PV=nRT. Ideal Gas Law
We see by inspection of the ideal gas law, there is a liner relationship between Pressure and Temperature of an ideal gas. So if the pressure is increased on the gas, then the Temperature will increase also.
Any questions please feel free to ask. Thanks and have a great day!
The best way to dry is to let it air dry after washing it with soap and water
I think the most appropriate answer is: the solvent being used in the experiment
<span>To correct for any light absorption not originating from the solute you will need to calibrate the tools with a solution that most similar to the sample.
Blank covete or standard solution can be used, but it was not ideal. By using the solvent as calibration, you can remove the reading from the solvent so your result only comes from the sample.

Answer: The partial pressure of neon is 173 mmHg
Explanation:
According to Dalton's law, the total pressure is the sum of individual pressures.
Given : 
=total pressure of gases = 490 mm Hg
= partial pressure of Helium = 215 mmHg
= partial pressure of argon = 102 mm Hg
= partial pressure of neon= ?
Thus partial pressure of neon is 173 mmHg
