Dissolving is a physical process.
It is a chemical change.
it is a chemical change because the stuuff dissolves so it is a chemical reaction.
Dissolving CO2 in water would be a physical reaction because neither the CO2 molecules, nor the H2O molecules are undergoing any change.
Frozen carbon dioxide is still carbon dioxide, so it is a physical change.
Carbon dioxide (CO2) ia chemical compound, not a property.
chemical and physical because some carbon dioxide is already in the air
carbon dioxide escapes from upon the opening soda can is it chemical or physical
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
Carbonation is the process of dissolving carbon dioxide (CO2) in a liquid, usually water.
i think it is chemical but it may be physical.
The sublimation of dry ice into gaseous carbon dioxide is a physical change. It does not undergo any chemical changes.
It is a change in physical state, which is a physical 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.
its a chemical reaction.
No, its a physical change.
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.
CO2 is the chemical formula for carbon dioxide.
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.
This is a chemical process.
It is a chemical change.
This is a chemical change.
No, dissolving solutes in a solvent is always a physical change!
It is a chemical reaction. The coal (which is mostly carbon) reacts with oxygen to form carbon dioxide.
physical reaction, because there is no change in its chemical composition.
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
