Redox Reaction Homework
For the following (Not Balanced rxn) chemical reaction, do the following:

Show all the oxidation of each "atom" above it.
Make the appropriate brackets with Reactant oxidation number ---> product oxidation number, then "lose or gain e^-
Make sure that one bracket is above chemical equation and another below
Then write down (as described in notes) what is oxidized, reduced, oxidizing agent, reducing agent.
If no oxidation numbers are changing from reactant to product, write NOT REDOX RXN (but must show oxidization numbers)

1. Fe₂O_3(s) + C_(s) ---> Fe_(s) + CO_2(g) [C - elemental carbon)]

2. H_2(g) + Cu₁O_1(s) ---> Cu_(s) + H₂O_1(g)

3. NaOH_(aq) + H₃(PO₄)_1(aq) ---> Na₃(PO₄)_1(aq) + H₂O_1(l)

4. Cl_2(g) + Ca₁Br_2(aq) ---> Ca₁Cl_2(aq) + Br_2(l)
