What defines an element?
Step 1 of 3
Chapter 18 Electrochemistry is the branch of chemistry that deals with the chemical action of electricity and the production of electricity by chemical reactions. Assigning oxidation numbers: Fe O + 3CO ------- 2Fe + 3CO 2 3 2 3+ (Fe2) (These elements balance each other) (O 36- (Oxygen usually has a charge of -2. 2*3=6) (O)2- (See above) 2+ (3C) (These elements must balance each other out) 0 (2Fe) (Elemental form has no charge) (3C) 4+ (See above) (O )4- (See above) 2 Note: The electric charge is not tied to the elements stoichiometry. A useful way to check this is to remember that the sum of the oxidation states is equal to the charge of the molecule: HCO
