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.
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=============================
How many moles of O2 are produced when 0.400 mol of KO2 reacts in this fashion?
The thermal decomposition reaction is:2 KO2------------K2O2 + O20,2 moles of O2 are produced from o,4 moles KO2.
What is the equation for potassium and oxygen react to form potassium oxide?
K + o2 = ko2
What is a formula for potassium?

What is the chemical formula of potassium super oxide?
It is KO2 .
How many moles of O2 g are produced by the reaction of 156 g CO2 g with excess KO2?
The reaction of carbon dioxide and potassium oxide is 4KO2 + 2CO2 = 2K2CO3 + 3O2. 156 grams of CO2 is 3.54 moles, which will produce 5.31 moles of O2.
What is the chemical symbol for superoxide?
KO2, [O2-] being the superoxide anion.
How many potassium atoms are there in potassium oxide?
K2O: 3 atoms in the molecule K2O2: 4 atoms in the molecule KO2: 3 atoms in the molecule
What is the chemical formula of ionic compound potassium oxide?
Three potassium oxides are known: K2O, KO2, K2O2.
