Exhaled air contains ___ and ___

Potassium superoxide , KO_(2) , is utilised in closed system breathing apparatus. Exhaled air contains CO_(2) and H_(2)O ,both of which are removed and the removal of water generates oxygen for breathing by the reaction 4KO_(2) (s) + 2H_(2)O(l) to 3O_(2)(g) + 4KOH(s) The potassium hydroxide removes CO_(2) from the apparatus by the reaction : KOH(s) + CO_(2)(g) to KHCO_(3) (s) (a) What mass of KO_(2) generates 24 gm of oxygen ? (b) What mass of CO_(2) can be removed from from the apparatus by 100 gm of KO_(2) ?

Observe following table and answer the questions given below . Why does exhaled air contain more carbon dioxide ?

An athelet takes 20 breaths per minute at room temperature. The air inhaled in each breath is 200mL which contains 20% oxygen by volume, while exhaled air contains 10% oxygen by volume. Assuming that all the oxygen consumed if used for converting glucose into CO_(2) and H_(2)O_((l)) , how much glucose will be burnt in the body in one hour and what is the heat produced ? ( Room temperature -27^(@)C and enthalpy of combustion of glucose is -2822.5kJ mol^(-1) at 0^(@)C)

Assuming that al the oxygen consumed if used for converting glucose into CO_(2) and H_92)O_((l)) , how much glucose will be burnt in the body in one hour and what is the heat produced ? ( Room temperature -27^(@)C and enthalpy of combustion of glucose is -2822.5kJ mol^(-1) at 0^(@)C)

A person takes 15 breaths per minute. The volume of air inhaled in each breath is 448 ml and contains 21% of oxygen by volume. The exhaled air contains 16% of oxygen by volume. If all the oxygen is used in the combustion of sucrose, how much of the Sucrose is burnt in the body per day & how much heat is evolved. Delta H_(com) of sucrose is = 6000 kJ mol^(-1) . Take temperature to be 300 K throughout. [Assuming V_("inhaled air") = V_("exhalded air"), P_(atm) = 1atm ]

Exhaled air does not contain the following gas.

Consider the following statements. (a) Vibration of vocal cords gererate voice Exhaled air create vibrations at vocal cords.
