Question

some chemical reactants are listed in the table below. complete the table by filling in the oxidation state of the highlighted atom. species oxidation state of highlighted atom n₂(g) br⁻(aq) na⁺(aq) cu⁺(aq)

Explanation:

Step1: Oxidation state of element in free form

For \(N_2(g)\), in free elemental form, oxidation state is \(0\).

Step2: Oxidation state of monatomic ion

For \(Br^-(aq)\), monatomic ion's oxidation state equals its charge, so it is \(- 1\).

Step3: Oxidation state of monatomic ion

For \(Na^+(aq)\), monatomic ion's oxidation state equals its charge, so it is \(+1\).

Step4: Oxidation state of monatomic ion

For \(Cu^+(aq)\), monatomic ion's oxidation state equals its charge, so it is \(+1\).

Answer:

species	oxidation state of highlighted atom
\(Br^-(aq)\)	\(-1\)
\(Na^+(aq)\)	\(+1\)
\(Cu^+(aq)\)	\(+1\)
