K2O is potassium oxide. Per means one more oxygen, so
K2O2 is potassium peroxide.
Look at H2O2 for hydrogen peroxide.
H2O2 is a dimer(the empirical formula is HO) as is K2O2(the empirical formula is KO). By the way, oxygen has an oxidation state of -2 in most compounds but in peroxides it is -1.
Write a formula for the ionic compound that forms between each of the following pairs of elements. 1. aluminum and oxygen Express your answer as a chemical formula. AlO and Al2O3 and Al2O3 the 2 was the bottom right cornor and I
Which of the following statements best describes p orbitals? a dumbbell with a ring around it a sphere around the nucleus a four-leave clover two lobes apposing each other Examine the three isotopes of potassium (K) below.
I need the oxidation half reactions, reduction half reactions, and net ionic equations for the following reactions: 1)magnesium +0.1M zinc sulfate 2)copper+0.1M zinc sulfate 3)zinc+0.1M copper(II)sulfate 4)zinc+3M HCl 5)copper+3M
Small quantites of hydrogen peroxide can be prepared by the action of an acid on an alkaline earth metal peroxide, such as barium peroxide. BaO2 (s) + 2HCl (aq) -> H2O2 (aq) + BaCl2 (aq) What mass of hydrogen peroxide should
David Robertson works as a chemical engineer for U.S. peroxide Corporation. David has 2500 gallons of commercial-grade hydrogen peroxide solution that is 60% pure hydrogen peroxide. How much distilled water(which is 0% hydrogen
Determine the volume of oxygen that is needed at STP to completely react with 5.63 g of potassium. 4K + O2 yields 2H2O I don't buy the equation. If K is reacting with oxygen, then the equation is 4K + O2 ==> 2K2O Actually, I
2mno4 - + 5h2o2 + 6h= 2mn 2+ + 5o2(gás) + 8h2o You must determine the percentage of hydrogen peroxide (H2O2) in a solution by permangan titration. In an acid solution, the permanganations will oxidize hydrogen peroxide to oxygen
Question: When a pink aqueous solution of potassium permanganate, faintly acidified with dilute sulfuric acid was treated with 10% aq. hydrogen peroxide, the reaction took place with the evolution of gas bubbles, and the pink
Redox titrations are used to determine the amounts of oxidizing and reducing agents in solution. For example, a solution of hydrogen peroxide, , can be titrated against a solution of potassium permanganate, . The following
