Balance this equation: Fe2O3 + CO --> Fe + CO2 in acidic solution. Use the addition of electrons to balance oxidation numbers as needed. As a reminder, you add H2O to balance oxygen molecules.
Step 1: Write 1/2 reactions and determine oxidation values (Hint: you should get Fe3+)
Step 2: Add H2O to balance Oxygen
Step 3: Add H+ ions to balance Hydrogen
Step 4: Add electrons to balance charges/oxidation values in reactants/products.
Step 5: Multiply to have equal number of electrons present in both 1/2 reactions.
Step 6: Recombine 1/2 reactions
Step 7: Balance/Cancel any identical reactants & products (hydrogen ions, water molecules, electrons)
Step 8: Verify mass and charges are balanced!
