when vinegar combines with baking soda they form gas bubbles is this experiment physical or chemical change?
please answer me
What else can I help you with?
Is bubbles a chemical change?
In and of itself, no. Both chemical and physical changes can create bubbles.
Is a root beer foat a chemical or physical reaction?
Depends, the drink itself is a chemical reaction, the CO2 bubbles. But the icecream and that is a physical reaction. Anything that changes state is a physical reaction.
Is pouring acid on a rock and producing bubbles physical or chemical?
chemical
Is it a physical or chemical change champagne bubbles when the cork is removed?
It is a physical change.
Do the bubbles in a pot of boiling water for noodles indicate chemical change?
No, the bubbles in boiling water for noodles do not indicate a chemical change. The bubbles are formed due to the physical process of water reaching its boiling point and turning into steam bubbles. This is a physical change, as only the state of the water molecules is changing, not their chemical composition.
Baking powder bubbles and gives off CO2 when it is moistened is it a chemical or physical change?
It is a chemical change.
Are water bubbles chemical or physical change?
Water bubble is a substance not a change.
Is bubbles fizzing a physical or chemical change?
Physical. If a substance releases bubbles, it is converting some of its liquid into a gaseous state. The chemical properties do not change, only its present state. A most common physical change is that of watching ice melt in glass of water.
What gas is represented by bubbles in an experiment?
Which experiment?
When baking soda is mixed with lemon juice bubbles are formed with the evolution of gas Is it a physical or chemical change?
it is a chemical change
Are bubbles a physical property?
No, bubbles are not a physical property. They are formed by gases trapped in a liquid or solid material, and are a visual representation of that specific arrangement and interaction of molecules. Bubbles themselves are physical entities that exhibit traits of fluids, such as surface tension.
Why is the coke and Mentos experiemnt a physical reaction?
The Coke and Mentos experiment is a physical reaction and not a chemical one because the chemical compounds involved are not changed. No "chemistry" happens, but only "physics" occurs. Let's look. Carbon dioxide (CO2) gas is dissolved in the Coke, and when the cap is removed, it begins to come out of solution and form bubbles. There is a complex issue regarding exactly where a bubble will form and how it will grow, but bubbles do form and grow. Dump in some Mentos and the surface of each of the Mentos provides a "zillion" sites for bubbles to form. They form quickly, then detach, and more bubbles quickly form. This results in a cascade of bubble formation and the dramatic result we see. And it's all about the CO2 coming out of solution and making bubbles rapidly. Those bubbles carry Coke with them to the top of the bottle as they make their way out, and we see the fountain form. The Mentos and Coke are unchanged, just as the CO2 is unchanged in this physicalreaction.The reaction of Diet Coke and Mentos is a physical reaction. Links can be found below to learn more.
