Question

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 because there is a release of heat and light.

Event 2 because the blue color mixes throughout the liquid.

Event 2 because the temperature is dropping in the liquid.

Event 1 because there is a color change.

Answer 1

Event 1 is an example of a chemical reaction.

Step-by-step explanation:

Whenever there is a chemical reaction, we can find that by means of a color change, formation of any gas, vapors, bubbles or any color or colorless precipitation, or by means of heat generation.

In the event 1 there is only a clear liquid in the beaker again it is added to a clear liquid in another beaker, forming an orange colored liquid , which shows that there is an occurrence of some chemical reaction.

So Event 1 is most likely an example of a chemical reaction.
