Which response includes all of the following that are single replacement reactions, and no other reactions?
Zanzabum

Only 2nd reaction is a single replacement reaction

<h3>What is a single replacement reaction?</h3>

A single replacement reaction is a reaction in which an element is replaced by another element in a compound.

It is often called a single displacement reaction

The reactants in this reaction are always pure elements and an aqueous compound.

When this reaction occurs, a new aqueous compound and other pure elements are formed as products.

We can write a general single replacement reaction as:

AB (aq) + C \rightarrow A + CB(aq)

Hence, only 2nd reaction is a single replacement reaction that is

Cl_2(g) + 2NaBr(aq)  \rightarrow Br_2(l) + 2NaCl (aq)

Disclaimer: The question was given incomplete on the portal. Here is the complete question

Question: Which response includes all of the following that is single replacement reactions and no other reactions?

  1. Li_2O(s) + CO_2(g) \rightarrow Li_2CO_3(s)
  2. Cl_2(g) + 2NaBr(aq)  \rightarrow Br_2(l) + 2NaCl (aq)
  3. HNO_3(aq) + KOH (aq) \rightarrow KNO_3(aq) + H_2O (l)
  4. SO_3(l) + H_2O \rightarrow H_2SO_4
