Achemical reaction’s main identifying sign is bubbles. true or false?

TRUE

It is true that bubbles is a sign of a chemical reaction. The formation of bubbles when an antacid tablet makes contact with water is an example of a chemical reaction where the mixture becomes saturated with gas.

Moreover, chemical property cannot be determined by merely viewing or touching the substance, for the substance composition must changed. This means that the substance molecular structure must be affected or bonds are broken to form new ones to indicate chemical change. Other indicators of chemical change includes change in temperature, color, odor and formation of precipitate.

i just did an experiment like this in my science class. also the answer is yes, it will get separated because they are two opposites meaning if they are opposite they can not attract.

hope this .!
