The reaction of baking powder to release carbon dioxide bubbles is a chemical change because it involves the formation of new substances (carbon dioxide gas) due to a chemical reaction. The carbon dioxide bubbles cause the dough to rise through physical expansion, but the underlying process of gas production is a chemical change.
What else can I help you with?
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.
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.
Is freezing carbon dioxide a chemical change or physical change?
Frozen carbon dioxide is still carbon dioxide, so it is a physical change.
Are Effervescent tablets bubbling in water physical properties?
Yes, the bubbling of effervescent tablets in water is a physical property. This is due to a physical reaction between the tablets and water that releases gas, typically carbon dioxide, resulting in the formation of bubbles. The effervescence is a visible indication of this physical change.
Is opening a soda can a chemical change?
Nope. The pressure keeps the Carbon Dioxide dissolved in the liquid, and when that pressure is relieved, the CO2 rapidly returns to its gaseous state. None of the molecules are reacting or changing, although the CO2 switches from aqueous to gaseous phase.
What chemical gives a soft drink it bubbles?
the carbon dioxide dissolved in the drinks gives it its bubbles

What are the chemical reactions in soda beverages?
The carbon dioxide bubbles from a chemical reaction.
Is bubbles in lemonade physical?
Bubbles in refreshing drinks have three origins: 1. Fermentation of sugars: a chemical process 2. Dissolving of air from the atmosphere after a vigourous stirring: a physical process 3. Adding carbon dioxide under pressure: a physical process
Is it a chemical or physical change when pop rocks pop in your mouth?
The pop that results is caused by the release of carbon dioxide bubbles that are encapsulated within the candy. This is a physical change, rather than a chemical reaction, because no new products are formed.
What chemical gives soft drink it's bubbles?
the carbon dioxide dissolved in the drinks gives it its 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 formation of bubbles a physical change?
If you ae talking bubbles released from a can of soda = physical. It is just carbon dioxide being released. If you are talking bubbles produced from a mixture of baking soda and vinegar = chemical. It is actually changing the chemical composition and releasing oxygen from the H2O.
C02 is a chemical syble for what compound?
CO2 is a chemical symbol for the compound known as carbon dioxide. Carbon dioxide is those bubbles dissolved in your soda pop.

Is warm water and yeast a chemical or physical change?
The mixing of warm water and yeast to create a chemical reaction that produces carbon dioxide gas is a chemical change. This is because the combination of the water and yeast results in the formation of new substances with different properties (gas bubbles).
Dry ice turning into carbon dioxide physical or chemical?
i think it is chemical but it may be physical.
