Potassium superoxide (KO2)reacts in the following equation: 4KO2 + 2H2O +4CO2 =4KHCO3 + 3O2 If a person wearing an oxygen mask exhales 0.85 grams of CO2 every minute, how many moles of KO2 are comsumed every 10.0 minutes? $\begingroup$ KO2 can decompose, but as Nilay Ghosh said, the product is not K2O; also, even that requires heating, which is simply not there. Avoid prolonged or repeated exposure. What mass of KO2 produces 235g of O2?b. Absorb on sand or vermiculite and place in closed containers for disposal. ... Notice that the reaction produces O2, which can be breathed, and absorbs CO2, a product of respiration. a. The theoretical capacity of KO2 is the absorption of 0.309 kg CO2 per kg of absorbent while 0.38 kg O2 are generated per kg of absorbent. 0.102250 mole of CO2 would react completely with (4/2) x 0.102250 = 0.2045 moles of KO2, but there is not that much KO2 present, so KO2 is the limiting reactant. [citation needed] The human body though will produce more CO2 than oxygen absorbed, thus a device or absorbent specifically for CO2 scrubbing may also be … The reaction of removal of water is KO2+H2O>>O2+KOH. The KOH produced is used to remove carbon dioxide by the following reaction; KOH+CO2>>KHCO3. Ventilate area and wash spill site after material pickup is complete. KO2 Beds with Dry and Humidified CO2 (Test Nos. What mass of CP2 can be removed by 123g of KO2? KS-4 - KS-7) 4-13 Maximum Temperatures Recorded by Thermocouples 118 in KO2 Beds During Reaction with Dry and Humidified CO2 4-14 Amounts of 02 Evolved and CO2 Absorbed During 121 Reaction of KO2 Beds with Humidified CO2 4-15 Comparison of the Reactivities of KO2 and 124 Ca(C2)2 with CO2 and H20 Section 7 - Handling and Storage HANDLING User Exposure: Do not breathe vapor. Correct answers: 1 question: KO2 is used in a closed-system breathing apparatus. Also, K2O is perfectly stable by itself (though it would surely react with CO2, given a chance). STORAGE Suitable: Keep tightly closed. (0.0351631 mol KO2) x (3/4) x (31.9989 g O2/mol) = 0.844 g O2 It removes carbon dioxide and water from exhaled air. Calculating grams of KO2 from equation. asage1510 Sun, 10/03/2010 - 10:44. The advantage of using KO2 in gas masks is that it absorbs CO2 at the same time releasing oxygen gas If 0 002 moles of KO2 is present in an atmosphere containing 44 8cm3 of CO2at STPfree from moisture , what will be the volume of O2 released at - Chemistry - Do not get in eyes, on skin, on clothing.
