What covalent compound is K2O?
K2O is an IONIC compound. containing K+ and O2-
What is the formula of a compound containing a potassium ion and an oxygen ion?
Potassium oxide = K2O = K+ O-2 Potassium peroxide = K2O2 = K+ O2-2 Potassium superoxide = KO2 = K+ O2-1
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 balance of K Br2 2KBr?
You need to have values for K, Br2 and 2KBr in order to find out the balance. For example, if you had the values as H2 + O2 = H20 the balanced chemical equation would be 10 H2 = H20.
What is the ionic compound between K and O?
Potassium oxide, with formula K2O.
What covalent compound is K2O?
K2O is an IONIC compound. containing K+ and O2-
What does potassium and oxygen form what ionic compound?
The combination of potassium (K) and oxygen (O2) produces K2O (potassium oxide). The balanced equation is 2K + O2 ==> K2O. The answer provided previously is incorrect. The compound KO does not exist.

What is the molecular mass for the chemical K2O?
2*39.10 (for 2 K) + 16.00 (for 1 O) = 94.20 a.m.u. for K2O
What is the mass of K2O contain equal number of moles of K atoms as are present in 1kg of KCl?
This mass is 631,75 g K2O.

What is the ionic compound between K and O?
Potassium oxide, with formula K2O.
What is the symbol for potassium plus oxygen?
An equation refers to a reaction, not an individual compound. The formula of potassium oxide is K2O. If you mean the equation for its formation from the elements, it is 4K + O2 --> 2K2O.
What is the empirical formula of a compound composed of 36.3 K and 7.43 O?
K: 36.3/39 = 0.931 molesO: 7.43/16 = 0.464 molesDividing both by 0.464, one gets K = 2 and O = 1Empirical formula = K2O (potassium oxide)
Give the mass of oxygen in 145g of Potassium Oxide?
145g of Potassium Oxide ( K2O )contains a mass of 24.6279566g of Oxygen ( O )& a mass of 120.3705041g of Potassium ( K )24.6279566g O + 120.3705041g K2 = 144.9984607g K2O * Potassium Oxide (K2O)- 94.195 g/mol* Oxygen ( O )- 15.999 g/mol* Potassium ( K )- 39.098 g/mol ( K2 ) - 78.196145g x (1mol/94.196g) = 1.539343497mol K2O 145g K2O = 1.539343497 mol K2O Please note the concept: K2O has a Molar Ratio of 1 Oxygen:2 PotassiumSo... 1.539343497 mol K2O is representative of(1 x 1.539343497 mol) of Oxygen &(2 x 1.539343497 mol) of Potassium 1.539343497mol O x [ ( 15.999g O ) / ( 1mol O) ] = 24.6279566g O and 1.539343497mol K x [ ( 39.098 g K ) / ( 1mol K ) ] x [ ( 2mol K ) / ( 1mol K ) ] =120.3705041g K2 Please Note: the Molar Ratio ex: (2mol/1mol) etc. is the last step 24.6279566g O + 120.3705041g K2 = 144.9984607g K2O only a 0.001062% of error (some percent of error is always present no matter what)Percent Error is calculated by%Error= [ ( experimental value - accepted value ) ] x100%
Potassium oxide formula?
K2o *Remember the symbol for potassium is K and not P, which is phosphorus
