What happens when you add zinc to hydrochloric acid using the pop test?
When zinc is added to hydrochloric acid, the reaction produces hydrogen gas. The "pop test" is a test for hydrogen gas, where a lighted match is extinguished with a "pop" sound when in contact with hydrogen gas. The presence of the "pop" sound indicates that hydrogen gas was produced in the reaction.
Are pop rocks a chemical change?
Yes, popping candy like Pop Rocks undergoes a chemical change when it releases carbon dioxide gas upon contact with moisture in the mouth. The reaction between the candy ingredients and saliva causes the popping sensation and sound.
What gas burns with a pop in lime water?
Carbon dioxide gas burns with a pop in lime water. When carbon dioxide gas is passed through lime water, it forms a milky precipitate of calcium carbonate, resulting in the pop sound due to the chemical reaction.
Is pop rocks exploding on your tongue a chemical reaction?
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.
What is the chemical reaction of pop rocks and coke?
Pop rocks contain carbon dioxide gas, which is released when they come in contact with moisture. When mixed with Coke (a carbonated beverage), the gas bubbles from the Pop Rocks accelerate the release of gas from the Coke, resulting in an effervescent reaction. This causes foaming and fizzing due to the rapid release of gas.

A glowing splint placed in a test tube causes a loud pop Is this chemical or physical change?
The loud pop indicates a chemical change. The glowing splint caused a reaction that produced a gas (likely oxygen or hydrogen) leading to the noise. This transformation is a result of a chemical reaction and not just a physical change.
Are pop rocks a chemical change?
Yes, popping candy like Pop Rocks undergoes a chemical change when it releases carbon dioxide gas upon contact with moisture in the mouth. The reaction between the candy ingredients and saliva causes the popping sensation and sound.
Is pop rocks mixed with soda a physical or chemical reaction?
the chemicals in the soda interact with the pop rocks and they some times blow up.
What gas burns with a pop in lime water?
Carbon dioxide gas burns with a pop in lime water. When carbon dioxide gas is passed through lime water, it forms a milky precipitate of calcium carbonate, resulting in the pop sound due to the chemical reaction.
What is indicated when a flaming splint causes a pop?
This means that in the chemical reaction that occured, hydrogen (H2) gas was produced. The splint will make the popping noise because literally there is a small explosion occuring, and water vapor will form.

What does the pop sound indicate when metals react with hydrochloric acid?
The popping sound is due to the rapid formation and release of hydrogen gas bubbles as the metal reacts with hydrochloric acid. This is a sign of a vigorous chemical reaction taking place.
Can you make popcorn on a radiator?
The radiator would not be hot enough to trigger the chemical reaction which makes the popcorn pop.
Is putting pop rocks in a soda and blowing up a balloon with it a chemical or physical reaction?
Mixing is a physical process.
Which thing gives colourless gas that burns with pop sound on reaction with dilute hcl?
Zinc metal gives off a colorless gas (hydrogen gas) that burns with a pop sound when reacted with dilute hydrochloric acid.
