18 Question (1 point) Self-contained self-rescue breathing devices, like the one in the figure below, convert CO2 into Oy according to the following (balanced) reaction: 4KO, (s) +200,(g) 2K,CO,(s)+302 (8) Image Credit: Jack Jackson/Alamy 1st attempt It See Periodic Table How many grams of KO2 are needed to produce 879.0 L of O, at 13.0°C and 1.00 atm?
please provide all the steps 7.37. Oxygen for First Responders In self-contained breathing devices used by first responders, potassium superoxide, KO2, reacts with exhaled carbon dioxide to produce potassium carbonate and oxygen: 4 KO,(s) + 2 CO2(g) – 2 K2CO3(s) + 3 O2(g) How much O, could be produced from 85 g KO,?
A self-contained breathing apparatus uses canisters of potassium superoxide, KO2, which consumes the CO2 exhaled by a person and replaces it with oxygen according to the following reaction: 4KO2(s) + 2CO2(g) → 2K2CO3(s) + 3O2(g) (a) What mass of KO2 in g is required to convert 6.30 L of CO2 at 21.0 oC and 656 mmHg into O2? Answer _____________________ (b) What is the rms speed of an O2 molecule at -9.4 oC?
Sodium peroxide is often used in self-contained breathing devices such as those used in fire emergencies because it reacts with exhaled carbon dioxide to form sodium carbonate and oxygen gas: a. balance the equation ___ Na2O2(s) + _____ CO2 (g) ----> _____ Na2Co3 (s) + O2 (g) b. If you begin with 3.50 g of Na2O2, how many moles of Na2O2 is that? c. If you begin with 3.50 g of Na2O2, how many moles of )2 can be produced...
