Yes it is a chemical reaction, where 2 cations replace each other.
AgNO3 + KI --> AgI + KNO3 is a double replacement (displacement) reaction.
This is a double displacement reaction.
An example of a double-replacement chemical reaction is: AgNO3 + NaCl -> AgCl + NaNO3 This reaction involves the exchange of ions between silver nitrate and sodium chloride to form silver chloride and sodium nitrate.
The general chemical equation for an endothermic double replacement reaction is AB + CD → AC + BD, where energy is absorbed from the surroundings. This type of reaction usually occurs in the presence of heat or other sources of energy to facilitate the breaking and reforming of chemical bonds.
A double replacement reaction is a chemical reaction where two reactant ionic compounds exchange ions to form two new product compounds with the same ions.Double replacement reactions take the form:A+B- + C+D- → A+D- + C+B-
Photosynthesis does not represent a single replacement reaction. It is a complex process that involves the conversion of light energy into chemical energy by plants, algae, and some bacteria. Photosynthesis involves multiple reactions, including light-dependent and light-independent reactions, to produce glucose and oxygen as end products.
A double replacement reaction occurs when two compounds exchange ions to form new compounds. It is determined by the solubility of the products formed and the presence of a driving force, such as the formation of a precipitate or a gas.
In a double replacement reaction a change of bonds between reactants occur.

This kind of reaction is called a double replacement or double displacement reaction, and has the pattern AB + CD --> AD + CB.
Single replacement
If it's a double replacement reaction, then 3MgI2 + Al2O3 --> 3MgO + 2AlI3
