Okay, let's clarify the terminology. Oxidizing means you'relosing electrons (reducing agent) and reducing means you're gainingelectrons (oxidizing agent).1. Ba (s) + S (s) -----> BaS (s)
Here, Ba and S are both at 0. When combined Ba has a +2 charge andS has a -2 charge.
Oxidized:__Ba_______ Reduced:____S_____ Ox.Agent:___S_____ Red.Agents:__Ba____ 2. CuCl2 (s) -----> Cu (s)+ Cl2 (g)
Cl is at -1, so if there's 2 that means Cu is at +2. When it reactsthen Cu goes to 0 as well as Cl.
Oxidized:____Cl_____ Reduced:___Cu______ Ox.Agent:____Cu____ Red.Agents:___Cl___ 3. Pb+4 (aq) + Cl-1 (aq)-----> Cl2 (g) + PbCl2 (s)
You already have the oxidation numbers for the first part. In thesecond, Cl is at 0 and Pb goes to +2.
Oxidized:____Cl_____ Reduced:___Pb______ Ox.Agent:___Pb_____ Red.Agents:___Cl___ 4. Fe+3 (aq) + P-3 (aq)-----> Fe (s) + P (s)
Same as above, except in the second they both go to 0.
Oxidized:___P______ Reduced:___Fe______ Ox.Agent:___Fe_____ Red.Agents:__P____ 5. Al(s) + I2 (g)-----> AlI3 (aq)
Al and I are both at 0. When reacted, Al goes to +3 and I goes to-1.
Oxidized:____Al_____ Reduced:____I_____ Ox.Agent:__I______ Red.Agents:___Al___
Hope this helps!
