In this lab, you will be breathing into a 5 L mixing chamber. The mixing chamber will start with “regular” air (20.93 vol% O2, 0.04 vol% CO2, and 79.03 vol% N2). You will inhale air through your nose (which is exposed to “regular” air) and exhale through your mouth into the mixing chamber. As your exhaled air is added into the chamber, an equal volume of air leaves the other end of the chamber so that the system remains at atmospheric pressure. Assume that the chamber is well-mixed.
Keep in mind the following points as you sketch the plot:
Calculate the volume of oxygen in 5L chamber after every exhale as shown in table below.. each exhale will have 16% oxygen concentration or a depletion by 5% from 21% of the air already in chamber. Similarly for CO2, the exhale percentage will increse to 4% from the original 0.04%
The graphs for O2 and CO2 are as attached below

please help with my pre lab additional information Pre-Lab Questions: 1. What is the definition of an 'equivalence point' in an acid/base titration? (1 point) 2. In part one of the experiment, you will prepare the acid solutions being titrated from a stock solution. Describe how you will accurately prepare 10.00 mL of 0.100 M HCl solution using a 1.00 M HCI stock solution. In your response to this question, be very specific about the quantities of stock solution and...

For the preparation and standardization of NaOH with KHP im supposed to boil water for 1hr and 30 min to remove CO2....the problem is that if I don't boil it for that long and (30 min) b/c of not enough time but I put the water I boiled for 1/2 hr aproximately into a NaOH bottle with a CO2 absorber and stored it there for a few days. I would assume that I would have to boil the water again...but...
