Dry air is 78% nitrogen gas, 21% oxygen gas, and 0.9% argon gas. These gases can be separated by distillation after the air is first converted to a liquid. In one of the steps in this process, filtered air is compressed enough to increase the pressure to about 5.2 atm.
a) To what volume must 175 L of air at 1.0 atm be compressed to yield a pressure of 5.2 atm?
b) The argon derived from the distillation of air can be used in fluorescent light bulbs. When 225 L of argon gas at 0.997 atm are distilled from the air and allowed to expand to a volume of 91.5 m3, what is the new pressure of the gas particls?
The total pressure of the mixture is 1.42 atm. What is the partial pressure of O2 in the mixture? (A) 0.211 atm (B) 0.426 atm
A solution which contains 41.0 g of an unknown molecular compound in 312 g of water freezes at -2.23°C. What is the molar mass of the unknown?
Water can be separated into hydrogen and oxygen gases by using electricity to break the bonds in a process called electrolysis. The reaction is:
They hydrogen atom is not actually electronegative enough to form bonds to xenon. Were the xenon-hydrogen bond to exist, what would be the structure of XeH4
