Balanced?
2AlBr3
Al: 2
Br:2x3=6
Al: 2
Br:6
Reaction Type
Balanced
Synthesis:
The elements combined, becoming simplified.
The reaction is exothermic. By combining the two elements a lot of heat is given off.
Reaction
Aluminum (Al)
Bromine (Br)
Aluminum-Bromide Reaction
Half-Reaction
Step 1: Balance Equation [COMPLETE]
Step 2: Identifying Oxidation/Reduction [COMPLETE]
Step 3: Seperate the elements, showing change
Step 4: Placing electrons to balence the half reaction
Step 5: Set electrons equal in both half-reaction
Step 6: Bask in the glory of being done
2Al + 3Br2
2AlBr3
What happens when you combine
the two?
Aluminum
Oxidation #
Bromide
Two elements combine creating Aluminum-Bromide
Which side of the equation to add the electrons to?
2Al (0) --> 2Al (+3) + e (-)
3Br2 (0) + e (-) --> 2Br3 (-6)
0 = Possitive [+3] + Negative Charge [Electrons]
Positive [0] + Negative Charge (Electrons) = -1
6 Al (+1) = 6e (-) =0
6Br (0) + 6e (-6) = 6Br (-6)
2AlBr3
6Al (0) --> 2Al (+3) + 6e
Balanced?
6 electrons = 6electrons
6 electrons in, 6 electrons out
Br: electrons out
Al: electrons in
Al: 0 [rule 1 first]
Br: 0 [rule 1]
Al: +1 -- +3
3Br: -1
Al: 0 --> +3; Lossed Electrons
Br: 0 --> -1; Gained Electrons
Al = Oxidized = Reducing Agent
Br = Reduced = Oxidizing Agent
