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.
KO2, [O2-] being the superoxide anion.
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-
K2O: 3 atoms in the molecule K2O2: 4 atoms in the molecule KO2: 3 atoms in the molecule
The potassium creates a small explosion. Afterwards there will be a small green flame.A2. This is a dangerous experiment, as potassium has a vigorous reaction with water. It will react with the moisture in the air with sufficient vigor to dissociate that water into oxygen and hydrogen which will again react. This sort of experiment must only be performed under an inert gas environment.Additionally, the potassium sample will have a surface film of kerosene from its storage, and this burning will add to the hazard. The flame is an orange-red.
You would need 18 grams to get the requirement. Using a chemical equation can help to solve this for you.
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.
The principal oxidation state of NA in NA2O2 and K in KO2 is +1
The thermal decomposition reaction is:2 KO2------------K2O2 + O20,2 moles of O2 are produced from o,4 moles KO2.
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.
+3
It is KO2 .
KO2, [O2-] being the superoxide anion.
Three potassium oxides are known: K2O, KO2, K2O2.
K + o2 = ko2
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
