It's a physical change because carbon dioxide still has it's same properties. It is not changed.
Added:
Even if you dissolve it in water it is still there thus making it a physical change and not a chemical change. If it were a chemical change then it would be changed for example, fire or burning things like logs and so forth. Dissolving something in water is not changing it completely it only has a minor change in how you see it, thus it is a physical change.
The only 'chemical' change might be considered to be the protolysis of water being slightly enhanced by the hydrogen bonding to carbon dioxide molecules. But that is more a (very weak) 'chemical' change of water molecules rather than of CO2 molecules:
(CO2)aq + 2 (H2O)l <<--> (HCO3-)aq + (H3O+)aq
An analogon to this is: dissolving HCl-gas to hydrochloric acid, which is also not considered as chemical change of HCl, only water molecules are becoming strongly acidic!
(HCl)aq + (H2O)l -->> (Cl-)aq + (H3O+)aq
What else can I help you with?
Dry ice turning into carbon dioxide physical or chemical?
i think it is chemical but it may be physical.
Is carbon dioxide a physical or chemical property?
Carbon dioxide (CO2) is a chemical compound consisting of one carbon atom bonded to two oxygen atoms. It is a chemical property because it describes the composition and arrangement of atoms in a substance. However, in terms of physical properties, carbon dioxide is a colorless, odorless gas at standard temperature and pressure.
When carbon dioxide comes from the fuel of the car is it a physical or chemical change?
chemical change
How many chemical reactions are possible regarding the formation of carbonic acid and the dissolving of calcite?
Dissolving calcite (calcium carbonate) in acids leads to release of carbon dioxide gas.
What is the name of this compound CO 2?
CO2 is the chemical formula of carbon dioxide.
Is carbon dioxide dissolving in water a chemical reaction?
Dah
Is dissolving carbon dioxide in water a chemical or physical reaction?
Dissolving CO2 in water would be a physical reaction because neither the CO2 molecules, nor the H2O molecules are undergoing any change.
Is freezing carbon dioxide a chemical change or physical change?
Frozen carbon dioxide is still carbon dioxide, so it is a physical change.
Dry ice turning into carbon dioxide physical or chemical?
i think it is chemical but it may be physical.
Is carbonating water a physical or chemical change?
Carbonating water is a physical change because it involves dissolving carbon dioxide (gas) into the water to create carbonated water. No new substances are formed during the process, so it does not involve a chemical change.
Is carbon dioxide a physical or chemical property?
Carbon dioxide (CO2) is a chemical compound consisting of one carbon atom bonded to two oxygen atoms. It is a chemical property because it describes the composition and arrangement of atoms in a substance.

When ethanol is burnt and converted into carbon dioxide and water is that a chemical or physical change?

When carbon dioxide comes from the fuel of the car is it a physical or chemical change?

How does carbon dioxide change?
Carbon dioxide can change by converting into solid form (dry ice) at temperatures below -78.5°C or by dissolving in water to form carbonic acid. In the atmosphere, it can undergo photochemical reactions to form ozone and other compounds.
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 physical or chemical change when acid on limestone produces carbon dioxide gas?
It is a chemical change.
Is antacid tablet fizzing and releasing carbon dioxide in the stomach physical or chemical?
This is a chemical process.
