When carbon dioxide comes from the fuel of the car is it a physical or chemical change?
chemical change
Is it possible to have a chemical and physical change at the same time?
When gunpowder explodes, it changes from a solid to a gas. That is why a gun works. Put a stick of wood on the fire. Watch the carbon burn as it turns to carbon dioxide. Feel it give off heat. Put gasoline in your car. When the gasoline combines with air it burns and turns to water and carbon dioxide. It also turns to hot gas and pushes your car.
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 evaporation rate of liquid carbon dioxide?
it's an example of physical change
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.
If you are burning coal be a physical or chemical change?
chemical. A chemical change is a change where a substance is changed and a new substance is formed. in the case of coal when the solid carbon in the coal combines with the oxygen in the air carbon dioxide (CO2) is formed.
What is the sublimation of carbon dioxide a chemical property or chemical change?
It is a change in physical state, which is a physical 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-

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.
Describe the physical and chemical changes that occur when a pot of water is boiled over a campfire?
The chemical changes are in the campfire- the wood combines with oxygen from the air, releases heat and carbon dioxide. The water does not have a chemical change, but does have a physical change- it changes from a liquid (water) to a gas (steam).
