Materials Balance question for assignment. Help needed.
Hi guys, i'm currently doing an assignment which seems to be beyond my knowledge and would like to ask for some helps. There are 2 questions im currently stuck on:
A natural gas analyzes CH4, 80.0 percent and N2, 20.0 percent. It is burned under a boiler and most of the CO2 is scrubbed out of the flue gas for the production of dry ice. The exit gas from the scrubber analyzes CO2, 1.2 percent; O2, 4.9 percent; and N2, 93.9 percent. Calculate the
(a) Percentage of the CO2 absorbed.
(b) Percent excess air used
2]A 10.0 m3 tank contains steam at 275°C and 15.0 bar. The tank and its contents are cooled until the pressure drops to 1.2 bar. Some of the steam condenses in the process.
a) How much heat was transferred from the tank?
b) What is the final temperature of the tank contents?
c) How much steam condensed (kg)?
(Use the steam table provided below).
Any help would be greatly appreciated. Thanks!

So what are the issues? We don't do peoples homework here on physics forums, you need a specific issue or question!
