It isn't.
Answer --> It is an example of phase change and thus a physical change. Not a chemical change

Is dry ice a chemical change or a physical change?
I just had this question for a chemistry and it is a physical change
What is dry ice physical or chemical change when left unattended?
Physical change, called sublimation. It still stays CO2
Is dry ice a element?
Dry ice is not an element. Dry ice is solid carbon dioxide, CO2, which is a compound.
Dry ice chemical formula?
Dry ice is solidified carbon dioxide (CO2).
Is dry ice turning into Carbon dioxide physical or chemical?
It is a physical change of state. CO2 solid (dry ice) is still CO2 as a gas.What does change is the physical heat content of the substance. By absorbing heat the physical state is changed from a solid at -109.3 degrees F to a gas at -109.3 degrees F. All the heat absorbed for the change of state is used by the molecules to expand in size (external energy), rather than to change in temperature. There is also a small amount of energy loss due to this change (entropy). Another calculation made is internal energy which is the internal molecular motive energy of the substance.
Is there any chemical change that can happen to dry ice?
no.
Is dry ice changing into theatrical smoke physical or chemical change?
Dry ice doesn't "turn into smoke". Dry ice causes moisture in the air to condense, forming fog. This is a purely physical, not chemical, change.
Is dry ice smoking at a concert is a physical or chemical change?
It is a physical change.
What happens after a substance goes through a chemical change?
Yes because when a chemical change happens the substance may not have some of the physical or chemical properties it had once before. An example of htis would be Dry Ice. This would be an example because dry ice was once just ice then they add a chemical and it turns into dry ice.
Is mealting dry ice a chemical change or physical change?
Any type of melting is a physical change.
Is freezing carbon dioxide to make dry ice a chemical change?
No, it's a physical change.
Is dry ice a chemical change or a physical change?
I just had this question for a chemistry and it is a physical change
Is it physical or chemical when dry ice evaporates without melting as time passes?
It is a physical change because the composition of the dry ice didn't change; it just changed forms
Is dry ice subliamating into carbon dioxide a chemical change?
no. a phase change is ALWAYS a physical change in the substance.
Is the temperature at which dry ice evaporates a chemical or physical?
Physical Change
Why is dry ice evaporation a physical chainge?
Dry ice is a solid form of cooled carbon dioxide. When it reaches room temperature it changes to gaseous carbon dioxide. Since, there is no change in the chemical composition of dry ice, it is called a physical change.
What is the chemical formula of dry ice and ordinary ice?
Dry ice is solid carbon dioxide. It has the chemical formula CO2. The correct formula for dry ice( cardice), which is solid carbon dioxide, is CO2.
