In a neutralization reaction, an acid reacts with a base.
In a redox reaction, one species oxidizes and another species reduces.
In a precipitation reaction, an insoluble solid is formed and it precipitates.

A. HNO₃(aq) + NH₃(aq) → NH₄NO₃(aq)

Neutralization. HNO₃ is an acid that reacts with NH₃ that is a Bronsted-Lowry base.

B. 2 Cu(s) + O₂(g) → 2 CuO(s)

Redox. Cu oxidizes from Cu to Cu²⁺ and O reduces from O₂ to O²⁻.

C. NaCl(aq) + AgNO₃(aq) → NaNO₃(aq) + AgCl(s)

Precipitation. Insoluble AgCl is formed.

D. 2 LiOH(aq) + H₂SO₄(aq) → Li₂SO₄(aq) + 2H₂O(l)

Neutralization. H₂SO₄ is an acid that reacts with LiOH, a base.

E. CaCl₂(aq) + K₂CO₃(aq) → 2 KCl(aq) + CaCO₃(s)

Precipitation. Insoluble CaCO₃ is formed.

There are several categories of chemical reactions. Chemical reactions are classified based on the kind of recombination that atoms of the reactants undergo.

A chemical reaction is said to have occurred when reactants are transformed into products by recombination of reactant atoms. New substances are formed each time a chemical reaction occurs.

The following chemical reactions are classified as follows;

HNO3(aq)+NH3(aq)→NH4NO3(aq) - Neutralization reaction

2Cu(s)+O2(g)→2CuO(s) - Redox reaction

NaCl(aq)+AgNO3(aq)→NaNO3(aq)+AgCl(s) - precipitation reaction

2LiOH(aq)+H2SO4(aq)→Li2SO4(aq)+2H2O(l) - Neutralization reaction

CaCl2(aq)+K2CO3(aq)→2KCl(aq)+CaCO3(s) - precipitation reaction

In a neutralization reaction, an acid is combined with a base to yield a salt. In a precipitation reaction two aqueous solutions are combined to yield an insoluble product. Redox reactions involve loss or gain of electrons.
