Examples: Fe, Au, Co, Br, C, O, N, F.     Compare: Co - cobalt and CO - carbon monoxide, To enter an electron into a chemical equation use {-} or e. To enter an ion specify charge after the compound in curly brackets: {+3} or {3+} or {3}. it even reacts with oxygen when potassium metal is cut open, a layer of potassium oxide is form. there is a website where you put in the skeleton equation and the website will balance it for you...however if your equation is not written rite then it will pick upp the error. Compound states [like (s) (aq) or (g)] are not required. Write the formula for the compound that has the atoms and, or groups in the order given: 3 Fe, and two groups made up of 1 As and 4 O.. Oxygen balance (OB, or OB%) is an expression that is used to indicate the degree to which an explosive can be oxidized.If an explosive molecule contains just enough oxygen to form carbon dioxide from carbon, water from hydrogen atoms, all of its sulfur dioxide from sulfur, and all metal oxides from metals with no excess, the molecule is said to have a zero oxygen balance. Potassium oxide is produced from the reaction of oxygen and potassium. Show Balanced Equation. The chief was seen coughing and not wearing a mask. Which of the following can be characterized as a strong electrolyte? How to Balance K + O2 = K2O (Potassium + Oxygen gas) - YouTube The answer will appear below, Always use the upper case for the first character in the element name and the lower case for the second character. For example, C6H5C2H5 + O2 = C6H5OH + CO2 + H2O will not be balanced, but XC2H5 + O2 = XOH + CO2 + H2O will. Compound states [like (s) (aq) or (g)] are not required. this reaction affords potassium oxide, K2O.
