Yes. They can. The clues of a chemical reaction are production of a gas, change in temperature, color change, production of a precipitate. If you take either baking soda or baking powder, and you add them to vinegar they both form bubbles in a chemical reaction.

How do you know that a chemical change is happening in the flask?
signs of a chemical reaction occurring include: -formation of a gas (bubbles) -change in color -transfer of energy (change in temperature, giving off light) -formation of a precipitate (if a solid forms out of solution)
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 are three observable signs to identify a chemical change?
chemical change doesn't apper outside easily as it is change in the chemical property of the element or the experiment done,specific methods can only be used to detect the chemical change for the substance under observation.
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 can be evidence of a chemical reaction?
Generally, you know a chemical reaction has occured if there is a change in temperature, a change in color, a formation of a gas (bubbles), or any kind of flame.
What are 2 signs of a chemical change?
1. precipitate forms 2. bubbles of gas appear
Is bubbles a chemical change?
In and of itself, no. Both chemical and physical changes can create bubbles.

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.
Which kind of change produces bubbles?
chemical
Baking powder bubbles and gives off CO2 when it is moistened is it a chemical or physical change?
It is a chemical change.
What is a sign that a chemiacl change occurred air bubbles or broken pieces?
air bubbles is a sign that a chemical change has occured
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.
What is one thing that can happen as a result of a chemical change?
Depending on the chemical change, sometimes color change, or appearance of bubbles.
What are the symptoms which show that the change is chemical?
1.Precipitation forms 2.Bubbles of gas appear 3.Colour changes occur 4.Temperature occurs 5.Change in volume occurs
What kind of change is happening when egg is boiled?
This is a chemical change.
Are water bubbles chemical or physical change?
Water bubble is a substance not a change.
