The question is incomplete, the complete question is:
Using the following portion of the activity series for oxidation half-reactions, determine which combination of reactants will result in a reaction.
A) Li(s) with Al(s)
B) Li(s) with (aq)
C) (aq) with Al(s)
D) (aq) with (aq)
<u>Answer: </u>The correct option is B): Li(s) with (aq)
<u>Explanation:</u>
The oxidation reaction is defined as the reaction in which a chemical species loses electrons in a chemical reaction.
A reduction reaction is defined as the reaction in which a chemical species gains electrons in a chemical reaction.
The chemical species will undergo a reduction reaction if the value of standard reduction potential is more positive or less negative.
For the given half-reactions:
As the value of standard reduction potential of aluminium is less negative. Thus, it undergoes reduction reaction and lithium will undergo oxidation reaction.
The half-reaction follows:
<u>Oxidation half-reaction:</u> ( × 3)
<u>Reduction half-reaction:</u>
<u>Overall cell-reaction:</u>
Hence, the correct option is B): Li(s) with (aq)
