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
What is the physical change of carbon dioxide and snow disappears?
The physical change that is happening is called sublimation. Sublimation is when a solid (snow) directly turns into a gas (carbon dioxide) without passing through the liquid state.
Is a heating process onto carbon dioxide a chemical reaction or a physical reaction?
Heating carbon dioxide is a physical reaction because it does not change the chemical makeup of the substance, only its physical state. The heat energy causes the carbon dioxide molecules to vibrate more rapidly, increasing their kinetic energy and leading to a phase change from solid to gas.
When Acid is placed into limestone and produces carbon dioxide gas is this a physical or a chemical change?
This is a chemical change.
Is freezing carbon dioxide a chemical change or physical change?
Frozen carbon dioxide is still carbon dioxide, so it is a physical change.
How does the carbon in coal become part of the carbon dioxide in the air?
When coal is burnt the chemical change combines carbon from the coal with oxygen from the air to produce carbon dioxide.
What happens to the carbon in the coal?
When coal is burned, the carbon in the coal combines with oxygen in the air to form carbon dioxide. This carbon dioxide is released into the atmosphere as a greenhouse gas, contributing to climate change.

Is freezing carbon dioxide to make dry ice a chemical change?
No, it's a physical change.
Is it physical or chemical change when acid on limestone produces carbon dioxide gas?
It is a chemical change.
When you burn a log has a physical change occurred?
Yes, carbon from the log combines with the air to form co2.

Is dry ice subliamating into carbon dioxide a chemical change?
no. a phase change is ALWAYS a physical change in the substance.
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-
