) The air in a room with volume 210m3 contains 0.2% carbon dioxide by volume initially. Fresher air with only 0.1% carbon dioxide flows into the room at the rate of 3m3/min and the mixed air flows out at the same rate. Find the percentage of carbon dioxide in the room as a function of time. What is the percentage of carbon dioxide in the room at the end of 30 minutes? What happens in the long run(that is what happens to your function when time t goes to infinity)?

A room has volume 100m3, and initially contains
normal air. Every minute, 2m3 of gas is pumped in, which
is 1.9m3 air, and 0.1m3 xenon. Every minute,
2m3 of well-mixed gas is pumped out. What volume of
xenon will be in the room after 1 hour?

A cylinder with a volume of 10 liters contains 1.32 kg of carbon
dioxide at a pressure of 75 atm. The carbon dioxide has a molecular
weight of 0.044 kg / mol and its molecule has 2 free rotations.
a) Calculate the gas temperature in the cylinder. If the
temperature is increased by 50 degrees, how much will the pressure
increase? Do not take into account the thermal expansion of the
cylinder
b) Calculate the number of molecules in the...

-An initially empty canister with volume of 0.2m3 f filled with
carbon dioxide from a line at 1000 kPa, 500K. Assume the process is
adiabatic and the flow continues until it stops by itself. Use
constant heat capacity to find the final mass and temperature of
the carbon dioxide in the canister and the total entropy generation
by the process.

The water in a shallow lake is at equilibrium with carbon
dioxide in the air. The pH was measured to be 7.0. What is the
alkalinity of the water in mg/L as CaCO3? The partial
pressure of CO2 is 1 X 10-1.5 atm. The
Henry's constant for CO2 is 3.162 X 10-4
moles/(L-atm) at 25oC.

VOLUME TECHNIQUE: This method is based on the volume of carbon
dioxide produced and collected.
MASS TECHNIQUE: This method is based on the difference in mass
before and after the reaction.
The mass of carbon dioxide calculated using the volume technique
will not be identical to the mass of the carbon dioxide calculated
using the mass technique. In this discussion, compare and contrast
the two techniques and the mass of carbon dioxide obtained by each
technique. Also discuss reasons for...

fraction of CO2 in air is 3.01×10-4. The Henry's law constant for
carbon dioxide is 4.48×10-5 M/mmHg.
