No, it is not a chemical reaction. Pop rocks simply melt in your mouth and release trapped CO2 (Carbon Dioxide) out into your mouth, and this release is what causes you to hear a pop, much as in popping a balloon.
A chemical reaction requires a substance to chemically change. Since the pop rock simply melts, it can always be cooled and would re-solidify.
If this were to be a chemical reaction, the enzymes in your mouth, or the water, would have to change the pop rock candy in a way that the atoms of the molecules that make it up would re-arrange to form CO2, leaving behind a totally different substance in your mouth after. Note that this change would not be easily reversible - another tell-tale method of detecting a chemical reaction.
The pop rocks fizz and sizzle and give out CO2 just like they do in your mouth. They do not kill you as the popular myth says.
The reaction that occurs when acid rain damages carbonate rocks is an acid-base reaction.
== == Acidity can dissolve certain rocks through chemical reaction.
It is chemical and mechanical both
They are rocks.

the chemicals in the soda interact with the pop rocks and they some times blow up.

honfel rocks are made of already existing rocks formed from heat, preasure or a chemical reaction. also its a metamorphic rock.
Mixing is a physical process.
warm temperatures; very moist
The mineral pyrite is composed of iron and sulfur. FeS2. And is created by a chemical reaction between the two under certain geologic conditions.
Chemical weathering of rocks is caused by a chemical reaction. Factors such as dissolution, carbonation, oxidation, or hydrolysis of rocks are factors of chemical weathering.
