Textbook Problem

In the following reactions, decide which reactant is oxidized and which is reduced. Designate the oxidizing agent and the reducing agent.

(a) C2H4(g) + 3 O2(g) → 2 CO2(g) + 2 H2O()

(b) Si(s) + 2 Cl2(g) → SiC14()

(a)

Interpretation Introduction

Interpretation:

In the given reaction, the oxidized and reduced reactant has to be decide and oxidizing and reducing agent should be designated.

Concept introduction:

An oxidizing agent gains the electrons and is reduced in a chemical reaction and it is electron acceptor.

A reducing agent loses electrons and is oxidized in a chemical reaction and it is electron donor.

The oxidation state is called as oxidation number, which describes degree of oxidation (loss of electrons) of an atom in a chemical compound. Theoretically, the oxidation state is positive, negative or zero.

Explanation

The given reaction is shown below,

  

The given compound is a neutral compound.  Generally, Oxygen behaves as an oxidizing agent, it oxidized ethane which forms carbon dioxide and water...
