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 else can I help you with?
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^+.
What is the oxidation number for O in K2O?
The oxidation number for O in K2O is -2. Oxygen typically has an oxidation number of -2 in most compounds. Since there are two oxygen atoms in K2O, the total oxidation number contributed by the oxygen atoms is -4.
How does K O2 and K2O balance?
To balance the equation of potassium reacting with oxygen to form both potassium superoxide (KO2) and potassium oxide (K2O), you would write it as 4K + O2 -> 2KO2 and 4K + O2 -> 2K2O. This ensures that both sides of the equation have the same number of each type of atom.
Is KO2 an acid or base?
Potassium Hydroxide (KOH) is a base. Bases contain hydroxide (OH) while acids contain hydrogen (H).
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.
What is the chemical formula of ionic compound potassium oxide?
Three potassium oxides are known: K2O, KO2, K2O2.
What is the correct formula for the ionic compound formed between potassium and oxygen?
The correct formula for the ionic compound formed between potassium and oxygen is K2O. Potassium is a Group 1 element with a +1 charge, while oxygen is a Group 16 element with a -2 charge. By balancing the charges, we get K2O as the formula for the compound.
The chemical formula for an ionic compound of potassium and oxygen is what?
the chemical formula for potassium and Oxygen is: K2O Because Potassium has a charge of 1+. And Oxygen has a charge of 2- Hope this helps!

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-
Is KO2 an acid or base?
Potassium Hydroxide (KOH) is a base. Bases contain hydroxide (OH) while acids contain hydrogen (H).
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 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.
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
