C) metal ions are produced when pure metals are oxidized. For example, C6H5C2H5 + O2 = C6H5OH + CO2 + H2O will not be balanced, but XC2H5 + O2 = XOH + CO2 + H2O will. E) all of the above, When the reaction shown is balanced, there are ________ atoms of oxygen and ________ atoms of (b) -h, where h is Planck's constant.
