Is freezing carbon dioxide a chemical change or physical change?
Frozen carbon dioxide is still carbon dioxide, so it is a physical change.
When carbon dioxide comes from the fuel of the car is it a physical or chemical change?
chemical change
We inhale oxygen and exhale carbon dioxide as a result of a change in our bodies. a. physical b. chemical?
We inhale oxygen and exhale carbon dioxide as a result of a change in our bodies. Answer - Chemical Change
Is Carbon dioxide filled with balloon a chemical change?
No. helium is released in outer air but does not lose or change its chemical formula
Is it physical or chemical change when acid on limestone produces carbon dioxide gas?
It is a chemical change.
Is combustion of a fuel that produces carbon dioxide an example of a chemical change?
Yes, combustion of a fuel that produces carbon dioxide is an example of a chemical change. In this process, the chemical composition of the fuel undergoes a change as it reacts with oxygen to form carbon dioxide and release energy.
What type of change is oxygen turning into carbon dioxide?
Chemical
When Acid is placed into limestone and produces carbon dioxide gas is this a physical or a chemical change?

Is acid on a limestone producing carbon dioxide gas a physical or chemical change?
The reaction of acid on limestone to produce carbon dioxide gas is a chemical change. This is because new substances with different properties (carbon dioxide gas and water) are formed during the reaction, changing the chemical composition of the limestone.
When baking biscuits and other quick breads the baking powder reacts to release carbon dioxide bubbles the carbon dioxide bubble causes the dough to rise is this a physical or chemical change and why?
The reaction of baking powder to release carbon dioxide bubbles is a chemical change because it involves the formation of new substances (carbon dioxide gas) due to a chemical reaction. The carbon dioxide bubbles cause the dough to rise through physical expansion, but the underlying process of gas production is a chemical change.
Is combining carbon dioxide and water to make sugar a physical change?
Combining carbon dioxide and water is a chemical change, not a physical change, but it doesn't make sugar. Carbon dioxide and water makes carbonic acid. CO2 + H2O <--> H2CO3-->H+ + HCO3-
