The images show two unrelated events occurring at separate times.

Event 1: A beaker pours a clear liquid into a second beaker, also full of clear liquid, creating an orange liquid. A glass holds clear liquid, with some areas of dark blue liquid surrounded by lighter blue liquid.

Which event is most likely an example of a chemical reaction?

Event 1 is an example of a chemical reaction.

Explanation:

Whenever if two solutions are mixed, then if there is any color change, or evolution of any vapors, bubbles or gas formation or if there is any formation of a color or white precipitate confirms that the occurrence of a chemical reaction.

If nothing happens said above then it is said that there is no chemical reaction occurs.

Here in the event 1 a clear liquid in one beaker poured into clear liquid in beaker 2 then there is a formation of orange liquid, which means there is a formation of a new colored liquid confirms that the chemical reaction occurred.
