When performing this experiment a control is required to show that inhaled air contains less carbon dioxide than exhaled air. Describe, using a labelled diagram, a suitable control procedure. [2009] The diagram shows the apparatus used by a pupil when performing an experiment in a school laboratory. The pupil blew (exhaled) air into test tube X.

Explain the difference in oxygen levels in inhaled and exhaled air. If nitrogen is not used by the cells of the body, account for the different composition between inhaled and exhaled air. During mouth-to-mouth resuscitation, exhaled air is forced into the victim’s trachea. Exhaled air contains a higher level of carbon dioxide than ...

Determine the mass in kg of air passing through this person per day. Use air at 25oC, 1 atm, and molecular weight of 29. If the air contains 21 mol % oxygen and the exhaled air contains 16 mol % oxygen, estimate the moles of oxygen absorbed by this person per day. If all of the absorbed oxygen is used to convert glucose (C6H12O6) into CO2 and H2O.
