The chemical reaction in this example is of environmental interest. Iron pyrite (Fesz) is often an impurity in
enot [183]

178.87 grams of sulphur dioxide is formed according to the  equation given.

Explanation:

The balanced chemical reaction for the process is:

4 FeS2 + 11 O2 ⇒ 2Fe2O3(-) + 8 SO2

the reaction involving FeS and oxygen having balanced chemical equation as:

moles of oxygen given as 3.84

so when  11 moles of O2 reacts to form 8 moles SO2

                3.84 moles of oxygen reacts to form x moles of SO2

\frac{8}{11} = \frac{x}{3.84}

x = \frac{30.72}{11}

2.792 moles of sulphur dioxide will be formed

The mass can be calculated as number of moles x molar mass of 1 mole of SO2

= 2.792 x 64.066

= 178.87 grams of sulphur dioxide is formed.

Which best describes the oxidizing agent in this reaction?
MissTica

For the reaction Cl₂(aq) + 2 Br⁻(aq) ⇒ 2Cl⁻(aq) + Br₂(aq), Chlorine (Cl) is the oxidizing agent because it gains an electron.

<h3>What is the oxidizing agent?</h3>

In a redox reaction, the oxidizing agent is the one that gains electrons, causing the other element to oxidize.

Let's consider the following redox reaction.

Cl₂(aq) + 2 Br⁻(aq) ⇒ 2Cl⁻(aq) + Br₂(aq)

The corresponding half-reactions are:

Reduction: 2 e- + Cl₂(aq) ⇒ 2Cl⁻(aq)

Oxidation: 2 Br⁻(aq) ⇒ Br₂(aq) + 2 e-

Which best describes the oxidizing agent in this reaction?

  • Bromine (Br) is the oxidizing agent because it gains an electron. NO. Br is the reducing agent.
  • Bromine (Br) is the oxidizing agent because it loses an electron. NO. Br is the reducing agent.
  • Chlorine (Cl) is the oxidizing agent because it gains an electron. YES.
  • Chlorine (Cl) is the oxidizing agent because it loses an electron. NO. Cl gains electrons.

For the reaction Cl₂(aq) + 2 Br⁻(aq) ⇒ 2Cl⁻(aq) + Br₂(aq), Chlorine (Cl) is the oxidizing agent because it gains an electron.
