If a piece of metal bubbles was place in acid is that a chemical change?
No, it is not a chemical change. For example, if you put gold bubbles into any single acid, no chemical change will take place.
When drain cleaner is added to water bubbles of hydrogen are produced Is what happens to form the bubbles when the cleaner is added a chemical or physical reaction?
If a gas is produced and it isn't a state change (such as steam bubbles forming), the reaction is a chemical change because the molecular makeup of either the water or the drain cleaner has changed and the hydrogen has been liberated.
Is bubbles a chemical change?
In and of itself, no. Both chemical and physical changes can create bubbles.
Do bubbles indicate a physical or chemical change?
Not always but they can. They may simply be an indication of a phase change, as when water boils. This is usually counted as a physical change rather than a chemical change. But if you add baking soda to vinegar, you will see bubbles as a result of a chemical change.
Is combustion of a fuel that produces carbon dioxide an example of a chemical change?
Yes, because new substances are produced in this reaction, it is an example of chemical change.

What are used to show the changes that take place during a chemical reaction?
Color change Precipitate (cloudy) Bubbles - gas is produced.
What does bubbling indicate in a chemical reaction?
The creation of bubbles in a liquid can result from:Boiling (formation of gas phase material) a physical changeDissolution of dissolved gasses (a physical change) from a liquid as it warmsThe creation of gases by reactants in an aqueous environment (chemical change)
Which kind of change produces bubbles?
chemical
Is floating bubbles are example of chemical change?
no, not really, the reason the bubble floats is because of the hot air slowly moving upward. there are no chemical processes going on
Is bubbling and fizzing a physical change or chemical change?
Gas bubbles are a chemical change. A common example can be soda. The bubbles in the soda are carbon, thus soda is carbonated, when you leave soda open and out in the open the carbon reacts with the oxygen in the air and forms carbon dioxide. Since there is a new chemical composition of the soda since it has lost carbon, also know as going flat, this is a chemical change. The above example is incorrect. The bubbles coming out of soda is not carbon reacting with oxygen;the bubbles are already carbon dioxide. Does pencil lead react with oxygen? The carbon dioxide in your soda is dissolved in solution. Gas bubbles in most other situations though ARE a sign of a chemical change.
What is one kind of energy produced during a chemical change in matter?
For example thermal energy.
Baking powder bubbles and gives off CO2 when it is moistened is it a chemical or physical change?
It is a chemical change.
