2. Ammonia combines with oxygen gas to form nitrogen gas and water vapor. A 3.55-L container of ammonia kept at 280 K and 1.66 bar is reacted with a 8.19 L of oxygen measured at 302 K and 0.776 bar. What is the volume of the final gas mixture measured at STP (1 bar, 273 K)?
A 3.50 L container of ammonia gas exerts a pressure of 655 mm Hg at a temperature of 245 K. Calculate the pressure of this same amount of gas in a 2.50 L container at a temperature of 225 K.
Imagine that you have an ideal gas in a 6.90 L container, and that 1350 molecules of this gas collide with a square-inch area of the container at any given instant. If the volume is increased to 55.2 L at constant temperature, how many collisions will occur per square inch of this larger container? Enter the number of collisions per square inch.
If the pressure of a gas in a container is increased while the number of molecules and temperature are held constant. What must happen? Volume must increase. k must decrease k must increase Volume must decrease.
Imagine that you have an ideal gas in a 4.70 L container, and that 2750 molecules of this gas collide with a square-inch area of the container at any given instant. If the volume is increased to 18.8 L at constant temperature, how many collisions will occur per square inch of this larger container?
Calculate the solubility (in M units) of ammonia gas in water at 298 K and a partial pressure of 8.00 bar . The Henry’s law constant for ammonia gas at 298 K is 58.0 M/atmand 1 bar=0.9869 atm. Express your answer in molarity to three significant figures.
QUESTION 1
2n molecules of nitrogen gas and 6n molecules
of hydrogen gas are inside a container and separated from each
other by a valve. The entire container is thermally and
mechanically isolated from the rest of the universe. The gases are
initially at the same temperature, 300 K. If the value is opened,
the gases interact with each other to form ammonia
(NH3). What is the final temperature (in K) of the
system if n molecules of ammonia are...
a (Pa m6 mol2) b (m3-mol-) 2.65 x 10-5 Hydrogen Н, NH3 0.0245 Nonideal Gases 3.71 x 10-5 Ammonia 0.4225 You have two 1.00 L containers at 298 K. One contains 1.00 mol of hydrogen gas while the second contains 1.00 mol of ammonia gas. (a) Calculate the pressure in each container according to the ideal gas law. (b) Calculate the actual pressure in each container.
The decomposition of ammonia gas (NH3) leads to the production of N2 gas and H2 gas. A chemist adds 4.0 mol of ammonia gas to a 2.0 L sealed, rigid container and heats it. It has been found that at equilibrium the number of moles of ammonia gas is 2.0 in the same 2.0 L container. Determine the equilibrium concentration of N2 and H2 gas,
1.Determine the number of entities (atoms or molecules) of C3H8 in a closed 5.94×10-1 L container at a pressure of 4.03×101 torr and a temperature of -93.91 °C. Report your answer to three significant figures. 2.A sample of SO2 gas has a volume of 5.09×103 mL at 2.31 atm and -176.73 °C. Calculate the new temperature (in K), when the volume of the gas is decreased by 479 mL. Assume the pressure does not change.
