Water is a chemical (pretty much all matter is technically made of chemicals), so it can undergo chemical changes.
Ice itself is not particularly reactive, but if it is melted into water (physical change), it can be chemically changed in a number of ways.
These are some relatively common ones:
1. Water can be mixed with CO2 (Carbon dioxide) to form Carbonic Acid, something with a different chemical structure from water.
2. Water can undergo electrolysis to be split into its component elements, hydrogen and oxygen.

Is melting ice cream a physical change or a chemical change?
Melting ice cream is a physical change because it has the ability to go back to it's frozen form and be ice cream again. The chemical identity of it isn't changed.
When milk spoils it smell bad is this a physical change or chemical change?
It is a chemical change because you cannot not make the smell go away, if you could it would be a physical change
Does dry ice go through a physical change or chemical change?
It is a physical change (phase change). Dry Ice is frozen carbon dioxide gas. At atmospheric pressure, liquid CO2 is unstable. So the frozen solid "sublimes" turning directly from a solid to a gas (absorbing heat from around it).
Is making a cake a physical or chemical change?
Baking a cake is a chemical change because the baking powder or soda (whichever one) undergoes a chemical reaction. you can tell because of the bumps or air bubbles. Not only that, but the chemical change is irreversible, you put the ingredients that make up the cake together and you can't change them back. The ingredients don't go back to their original form. You can tell it's a chemical change becaue of the heat, rising, and odor.
What happens when a chemical change does not go through completion?
The chemical reaction is interrupted.
Is melting ice cream a physical change or a chemical change?
Melting ice cream is a physical change because it has the ability to go back to it's frozen form and be ice cream again. The chemical identity of it isn't changed.
Is ice cubes shrinking a physical or chemical change?
It's a physical change.. it can go back to the way it was before.
Is ice cream melting in a bowl a physical or chemical change?
Melting ice cream is a physical change because it has the ability to go back to it's frozen form and be ice cream again. The chemical identity of it isn't changed.
How tyo recgonize chemical and physical change?
think if it can be reversed. if it is easially reversed, it is most likely physical. ie. if you bake a cake, you cant make it go back to a batter, so it is a chemical change. if you freeze an ice cube, you can just melt it and it goes back to water, so its a physical change.
Is ice meeting into water a physical or chemical change?
it's physical change
When milk spoils it smell bad is this a physical change or chemical change?
It is a chemical change because you cannot not make the smell go away, if you could it would be a physical change
Why is water freezing into ice a physical change?
You can always undo a physical change by reversing the process. i.e. when you freeze water it turns into ice and when you heat the ice it turns back into water. Therefore it is a physical change.
Why use dry ice to make stage effect instead of water ice?
Dry ice goes through one change to make "fog", but water ice has to go through two changes to become a gas.You could use water ice to make fog, but it would have to go through the liquid phase before it evaporates or boils. But dry ice, instead of melting and evaporating, will go through what is called sublimation, which is the change of matter of solid to gas.
Ice melting physical or chemical?
It is a Physical Change. Melting it does not change what components/elements are found in snow. It is just a phase change from solid to liquid.
Does dry ice go through a physical change or chemical change?
It is a physical change (phase change). Dry Ice is frozen carbon dioxide gas. At atmospheric pressure, liquid CO2 is unstable. So the frozen solid "sublimes" turning directly from a solid to a gas (absorbing heat from around it).
Is the setting of concrete a physical or chemical change?
It's a physical change.It's a chemical change. The concrete hardens through a chemical reaction called hydration :)Its a physical change. The Chemical change already happened when the water was added. The concrete powder became hydrated turning it into usable concrete.
Are rotten leaves a physical or chemical change?
Both, but chemical dominates.
