Sure, let’s analyze each of the given chemical reactions and identify the type of reaction. Here's the step-by-step solution:

1. Reaction:
[tex]\[ NaNO_2 + HCl \longrightarrow NaCl + HNO_2 \][/tex]
- Type of Reaction:
This reaction involves the exchange of ions between two compounds to form new compounds. This is known as an exchange (double replacement) reaction.

2. Reaction:
[tex]\[ Ba(ClO_3)_2 \longrightarrow BaCl_2 + 3 O_2 \][/tex]
- Type of Reaction:
This reaction involves the breakdown of a single compound into two or more simpler substances. This is known as a decomposition reaction.

3. Reaction:
[tex]\[ CaO + CO_2 \longrightarrow CaCO_3 \][/tex]
- Type of Reaction:
This reaction involves the combination of two or more substances to form a single compound. This is known as a combination (synthesis) reaction.

4. Reaction:
[tex]\[ ZnSO_4 + Mg \longrightarrow Zn + MgSO_4 \][/tex]
- Type of Reaction:
In this reaction, one element displaces another element in a compound. This is known as a displacement (single replacement) reaction.

To summarize:

- NaNO_2 + HCl \longrightarrow NaCl + HNO_2 is an exchange (double replacement) reaction.
- Ba(ClO_3)_2 \longrightarrow BaCl_2 + 3 O_2 is a decomposition reaction.
- CaO + CO_2 \longrightarrow CaCO_3 is a combination (synthesis) reaction.
- ZnSO_4 + Mg \longrightarrow Zn + MgSO_4 is a displacement (single replacement) reaction.

Therefore, the correct associations are:
- \(NaNO_2 + HCl \longrightarrow NaCl + HNO_2\) ⟶ exchange (double replacement).
- \(Ba(ClO_3)_2 \longrightarrow BaCl_2 + 3 O_2\) ⟶ decomposition.
- \(CaO + CO_2 \longrightarrow CaCO_3\) ⟶ combination (synthesis).
- [tex]\(ZnSO_4 + Mg \longrightarrow Zn + MgSO_4\)[/tex] ⟶ displacement (single replacement).
