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 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.
What is silicon dioxide soluble in?
The only chemical which effectively dissolves silicon dioxide is hydrofluoric acid. But note that silicon dioxide does dissolve to a very slight extent in water. The beaches are not dissolving away into the ocean, but some tiny amount of silicon dioxide is dissolving.
What is the chemical equation for the reaction of coal and carbon dioxide?
CO2,g + Cs --> 2COg is the chemical reaction equation.
When limestone fizzes when acid is added is physical or chemical change?
chemical change
When a rocket is launched is it physical chemical or nuclear change?
when fireworks go off, the energy released show a chemical reaction. gasses such as carbon dioxide and particles of smoke go up in the air.
Is carbon dioxide dissolving in water a chemical reaction?
Dah
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 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 this a physical or chemical change when you pour vinegar into baking soda?
This is a chemical change because a chemical reaction occurs, creating a whole new substance (carbon dioxide).
Is the reaction between carbon dioxide and limewater physical?
Since it gives differed products, its a chemical change.
Is dissolving carbon dioxide in water a physical or chemical 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 > (Cl-)aq + (H3O+)aq
Is explosion of nitroglycerin a chemical or physical change?
it would be a chemical reaction mArKe ^_^
How does carbon dioxide change?
chemical because it is changing the state from solid to a gas in which is a chemical change
What is silicon dioxide soluble in?
The only chemical which effectively dissolves silicon dioxide is hydrofluoric acid. But note that silicon dioxide does dissolve to a very slight extent in water. The beaches are not dissolving away into the ocean, but some tiny amount of silicon dioxide is dissolving.
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
If a molecule of a carbon dioxide is released on a chemical reaction How is it represented in the chemical equation for the reaction?
The representation is CO2(g).
What is the chemical equation for the reaction of coal and carbon dioxide?
CO2,g + Cs --> 2COg is the chemical reaction equation.
