1. (9 pts.) Given the following four substances: (i) CH₂Br2 (ii) C₂04² (iii) CO3² (iv) C₁1H1602 (it's a real compound and NOT a peroxide!) a) Determine the oxidation number of C in each substance above: 1) 11) HI) M. I b) If the following redox half-reaction occurs: C₂04² - CO² 1) would this be an oxidation or reduction half-reaction in terms of the change in oxidation state for C? II) would the C in C₂042 be classified as an oxidizer or as a reducing agent, as it undergoes the change to the carbonate ion? III) how many electrons would be involved in this change of oxidation state (number) for C when the given half-reaction (C₂04 2- CO₂-2) is properly balanced?
