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
What is a formula for potassium?
KO2
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?
For every 4 moles of KO2 consumed, 3 moles of O2 are produced. Since the molar mass of KO2 is 71.097 g/mol, 323.2 grams of KO2 is approximately 4.55 moles. Therefore, 3/4 * 4.55 = 3.41 moles of O2 are produced. This is equivalent to 6.83 grams of O2.
How do you balance KO2 plus H2O - KOH plus O2?
The balanced equation for KO2 + H2O is 2KO2 + 2H2O -> 2KOH + O2. This means that for every 2 moles of KO2 and H2O, you get 2 moles of KOH and 1 mole of O2.
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.
How many grams of KO2 are needed to form 8.5 grams of O2?
One mole of KO2 produces 1 mole of O2. The molar mass of KO2 is 71.1 g/mol and that of O2 is 32 g/mol. So, 8.5 g of O2 would require (8.5 g / 32 g/mol) x 71.1 g/mol = 18.95 grams of KO2.
Why is KO2 formed when you add K to O wasn't it supposed to be K2O?
When potassium and oxygen react, the most stable compound formed is potassium oxide (K2O). KO2 can be formed when there is an excess of oxygen present. In this case, oxygen binds to potassium to form potassium superoxide (KO2) instead of the normal oxide.
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?
The minimum amount of KO2 required for the apparatus to produce enough oxygen for a 15-minute emergency exit depends on the flow rate of oxygen required by the user and the reactivity of KO2. Typically, a 500g cartridge of KO2 can provide enough oxygen for 15-30 minutes of use in emergency situations. It's essential to test the apparatus to determine the exact amount needed for 15 minutes.
What is the equation for potassium and oxygen react to form potassium oxide?
K + o2 = ko2
Which formula represents a peroxide a k2o b k2o2 c ko2 dcao e ca2o2?
The correct formula for peroxide is option (c) KO2. This compound contains the peroxide ion O2^2- and potassium cation K^+.
How many grams of KO2 would be required to produce 1120.0L of O2 at 20.0 degrees Celsius and 1.00atm?
To determine the amount of KO2 required to produce 1120.0 L of O2 at 20.0°C and 1.00 atm, we need to use the ideal gas law. First, calculate the moles of O2 using PV = nRT. Then, use the balanced chemical equation for the decomposition of KO2 to O2 to find the molar ratio and the mass of KO2 needed.
