Dissolving carbon dioxide in water a chemical change or a physical change?

it is a chemical change because the stuuff dissolves so it is a chemical reaction.


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.


Is carbon dioxide a physical or chemical property?

Carbon dioxide (CO2) ia chemical compound, not a property.


When you inhale oxygen and exhale carbon dioxide is that a physical change or a chemical change?

chemical and physical because some carbon dioxide is already in the air

Is dissolving carbon dioxide in water a chemical or physical change?

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+)aqAn 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 is chemical carbonation?

Carbonation is the process of dissolving carbon dioxide (CO2) in a liquid, usually water.


Dry ice turning into carbon dioxide physical or chemical?

i think it is chemical but it may be physical.


Is dry ice turning into carbon dioxide a physical or chemical change?

The sublimation of dry ice into gaseous carbon dioxide is a physical change. It does not undergo any chemical changes.


What is the sublimation of carbon dioxide a chemical property or chemical change?

It is a change in physical state, which is a physical change.


Is the formation of carbon dioxide a chemical change?

No. The formation of carbon dioxide is a change in physical state from the gas phase to the solid phase, which is a physical change.




Is dry ice turning into Carbon dioxide physical or chemical?

Carbon dioxide changing from solid dry ice to a gas is a change of physical state, the chemical composition and formula still remains the same.


What is the chemical formula of carbon dioxide?

CO2 is the chemical formula for carbon dioxide.


Is bubbles of carbon dioxide evidence of a chemical change?

Yes and no. Bubbles of carbon dioxide effervescing from a soft drink is a physical change. Bubbles of carbon dioxide produced as vinegar reacts with baking soda is a chemical change.





Is dissolution of sulphar in carbon disulfide a chemical change?

No, dissolving solutes in a solvent is always a physical change!


Is burning coal a chemical or physical reaction?

It is a chemical reaction. The coal (which is mostly carbon) reacts with oxygen to form carbon dioxide.


Is a heating process onto carbon dioxide a chemical reaction or a physical reaction?

physical reaction, because there is no change in its chemical composition.


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
