What coefficient should be used to make the following equation balance

1.	What coefficient should be used to make the following equation balanced Na2+ O2 gives -No
Answer» Na + O2 = Na2O - Chemical Equation Balancer.Explanation:To balance a chemical equation, enter an equation of a chemical reaction and press the Balance button. The balanced equation will appear above.Use UPPERCASE for the first character in the element and lowercase for the second character. EXAMPLES: Fe, Au, Co, Br, C, O, N, F.Ionic charges are not yet supported and will be ignored.Replace immutable GROUPS in compounds to avoid ambiguity. 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.You can use parenthesis () or BRACKETS [].How To Balance EquationsRead our article on how to balance chemical equations or ask for help in our chat.You can also ask for help in our forums.
