Question

$4Fe+3O_2\to 2{Fe}_2{O}_3$
$I$. In the reaction shown above, oxygen is an oxidizing agent.
$II$. Oxidizing agents become oxidized during chemical reactions.

• A. Statement $I$ is true, Statement $II$ is true
• B. Statement $I$ is true, Statement $II$ is false
• C. Statement $I$ is false, Statement $II$ is true
• D. Statement $I$ is false, Statement $II$ is false

Answer 1

Answer: (B)

Statement $I$ is true, Statement $II$ is false

$4Fe+3O_2⟶2F{e}_2{O}_3\downarrow \downarrow 00⟵\text{( Oxidation no.)}$

In $F{e}_2{O}_3$ oxidation no. of $Fe$ be $x$.

So, $2\left(x\right)+3(-2)=0x=3$

$I)$ Oxidation no. of $Fe$ changes from $0$ to $+3$. So, it is oxidised. Oxygen made it to oxidise. So, Oxygen is the oxidising agent here.

$I)$ Oxygen reduced here from $0$ to $-2$. So, oxidising agents become reduced during chemical reactions.
