Best ResponseYou've already chosen the best response.0Put on the ox number by the following rules: http://www.dummies.com/howto/content/rulesforassigningoxidationnumberstoelements.html Element which get change in ox.n. are or ox or red. Whan you had a raction containing ox and red atoms, its a redox

Best ResponseYou've already chosen the best response.0Rule 1: The oxidation number of an element in its free (uncombined) state is zero — for example, Al(s) or Zn(s). This is also true for elements found in nature as diatomic (twoatom) elements
