A 149mL bubble of hot gas at 217?C and 1.70atm is emitted from an active volcano. What is the final temperature, in ?C, of the gas in the bubble outside the volcano if the final volume of the bubble is 161mL and the final pressure is 0.827atm, if the amount of gas remains constant?
What is the mole fraction of ethanol in a solution made by dissolving 14.6 g of ethanol in 53.6 g of water?
A compound contain 60.87% carbon, 4.38% hydrogen, and 34.75% oxygen then determine its empirical formula?
If you fill the larger tank with oxygen to a pressure of 155atm , to what pressure should you fill the acetylene tank to ensure that you run out of each gas at the same time? Assume ideal behavior for all gases.
we know that actually it is filled with a mixture of gases called air. If the flask volume is 4.00 L, and the air is at standard temperature and pressure, how many gaseous molecules does the flask contain?
A large cylinder of He gas,such as that used to inflate balloons,has a volume of 25.0 L at 22 Celsius and 5.6 atm. how many moles of He are in such a cylinder ?
the pressure of a sample of a 1000 mL sample of gas at 10.0C increases from 700 mm Hg to 900 mm Hg. If the volume is unchanged, what is the new temperature

You performed this fractional distillation using an air condenser as the "fractionating" column. Explain why the distillate may have been obtained in higher purity if you would have used a fractionating column packed with glass beads.
Calculate the wavelength and frequency of an emitted gamma particle having the energy of 1.29x 10^11 J mol. Enter in scientiic notation.
Based on Liquid Chromatography, how can I changed if the capacity value and selectivity value and resolution value is not in the proper range?
