(c) \(2 \mathrm{Al}(s)+3 \mathrm{Cl}_2(g) \longrightarrow 2 \mathrm{AlCl}_3(s)\)
ANSWER:Step 1 of 2
Here, we are going to identify the substance that is oxidized in the given reactions.
The term “oxidation” is defined as the addition of oxygen/electronegative element to a substance or removal of hydrogen/ electropositive element from a substance. The substance which undergoes oxidation are said to be oxidized.
Whereas the term “reduction” is defined as removal of oxygen/electronegative element from a substance or addition of hydrogen/ electropositive element to a substance.
