How many moles of O2 g are produced by the reaction of 156 g CO2 g with excess KO2?
To calculate the moles of O2 produced, first find the moles of CO2 using its molar mass, which is 44.01 g/mol. Then, use the mole ratio from the balanced equation to find the moles of O2 produced. Finally, multiply the moles of CO2 by the mole ratio to get the moles of O2 produced.
What is the oxidation number of O in KO2?
KO2 is rare and is called potassium superoxide. It consists of K+ ion and O^2- ion. In this case, the oxidation number of O would be 1-. If, however, you meant to ask about K2O (potassium oxide), then the oxidation number of O would be 2-
What is the chemical symbol for superoxide?
The chemical symbol for superoxide is O2-.
Which alkali metal can react with oxygen to form peroxide or superoxide?
The metal of copper can react with oxygen. This is a metal that is very reactive when ti is combined with different substances.
Which chemical is used in submarines to form oxygen?
Chemicals aren't used to make O2 on board modern submarines; they use electrolysis to separate the Hydrogen and Oxygen in DI water, then store the O2 in tanks outside the pressure hull. The hydrogen is bled overboard as tiny bubbles (in the wine.... make me feel happy...make me feel fine).
How many grams of KO2 are needed to form 8.5 grams of O2?
You would need 18 grams to get the requirement. Using a chemical equation can help to solve this for you.
How many O2 molecules are produced per milligram of KO2 consumed 323.2 grams are consumed of KO2. The equation is 4KO2 2CO2 -- 2K2CO3 3O2?
323.2 grams of KO2 is equal to 4.55 moles of KO2. Per the equation, 3.4125 moles of O2 is produced which is equal to 2.055 E24 molecules of oxygen. This means that every mg of KO2 produces 6.36 E18 molecules of O2.
What is the chemical formula of potassium super oxide?
The chemical formula of potassium superoxide is KO2.
How many moles of O2 are produced when 0.400 mol of KO2 reacts in this fashion?
The balanced chemical equation for the reaction would be: 4KO2 + 2CO2 → 2K2CO3 + 3O2 Since the molar ratio between KO2 and O2 is 4:3, 0.400 mol of KO2 would produce: 0.400 mol KO2 * (3 mol O2 / 4 mol KO2) = 0.300 mol O2
How many grams of KO2 would be required to produce 1120.0L of O2 at 20.0 degrees Celsius and 1.00atm?
Use.PV = nRTTo get moles O2. ( 20.0o C = 293.15 Kelvin )(1.00 atm)(1120.0 L) = (X moles)(0.08206 L*atm/mol*K)(293.15 K)Moles = 1120.0/24.56= 45.60 moles O2-----------------------------------now,45.60 moles O2 (1 mole KO2/2 mole O2)(71.1 grams/1 mole KO2)= 1621 grams potassium oxide required=============================
What is a formula for potassium?
KO2
How many moles of O2 g are produced by the reaction of 156 g CO2 g with excess KO2?
To calculate the moles of O2 produced, first find the moles of CO2 using its molar mass, which is 44.01 g/mol. Then, use the mole ratio from the balanced equation to find the moles of O2 produced. Finally, multiply the moles of CO2 by the mole ratio to get the moles of O2 produced.
What minimum amount of KO2 is required for the apparatus to produce enough oxygen to allow the user 15 minutes to exit in an emergency?
This question can not be answered because KO2 is not an existing chemical compound and the probable mistaken compound K2O (potassium oxide) does not produce free oxygen (O2) in a normally possible chemical reaction.
How do you balance KO2 plus H2O - KOH plus O2?
The reaction is:4KO2 + 2H2O ---> 4KOH + 3O2
What is oxidation number for o in Ko2?
The oxidation number for oxygen (O) in KO2 is -1. Since the overall charge of the compound is 0, the oxidation number of potassium (K) is +1.
Why is KO2 formed when you add K to O wasn't it supposed to be K2O?
when k(potassium)added too(oxygen),it forms ko2(potassium oxide)because one molecule of k is reacted with o which contians always two molecules that means o+o=o2,therefore k+o=ko2 not k2o and there is one more reason that when one metal react with oxygen it forms oxides that is O2
What is the equation for potassium and oxygen react to form potassium oxide?
K + o2 = ko2
