Is freezing carbon dioxide a chemical change or physical change?
Frozen carbon dioxide is still carbon dioxide, so it is a physical change.
What colour would Carbon dioxide change limewater to?
Carbon dioxide.
Which organs are oxygen and carbon dioxide changed?
Oxygen and carbon dioxide change in the lungs.
Is carbon dioxide a reversable or irreversible reaction?
This is a reversible change as it involves a change in the state of a substance. Also, by applying pressure and lowering the temperature, gases carbon dioxide can be converted back into dry ice.
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-
How can you prove in an experiment that carbon dioxide concentration and temperature are limiting factors?
To change (increase or decrease) carbon dioxide concentration and temperature (in different experiments, not simultaneously) and to measure the effect on growth.
Why does adding carbon dioxide to BTB solution cause a color change?
BTB is an acid indicator. by adding carbon dioxide to the solution, it will turn into carbonic acid (a weak acid) turns green in low concentration and yellow in high concentration.
Is freezing carbon dioxide a chemical change or physical change?
Frozen carbon dioxide is still carbon dioxide, so it is a physical change.
Does plants change carbon monoxide to carbon dioxide?
plants do not change carbon monoxide into carbon dioxide. they, on the other hand, convert carbon dioxide in to oxygen.
What colour would Carbon dioxide change limewater to?
Carbon dioxide.
Which organs are oxygen and carbon dioxide changed?
Oxygen and carbon dioxide change in the lungs.
What must be done to carbon dioxide gas to change it to solid?
the cold air can change the carbon dioxide gas to a solid
If you could break up a carbon dioxide molecule would you still have carbon dioxide?
Although the molecule is broken up it does not change the fact that it is carbon dioxide. Therefore you still have carbon dioxide.
Which receptor is likely to detect changes in carbon dioxide and oxygen concentration in the blood?
The receptors that are likely to detect changes in carbon dioxide and oxygen concentration in the blood are chemoreceptors located in the aorta and carotid arteries. These chemoreceptors detect changes in the pH of the blood and send signals to the brain to regulate breathing heart rate and other bodily functions. The receptors are sensitive to the following: Carbon dioxide concentration Oxygen concentration pH of the bloodThe chemoreceptors are located in the walls of the aorta and carotid arteries and are sensitive to the changes in carbon dioxide and oxygen concentrations. When the concentrations of these two gases change the chemoreceptors send signals to the brain which then responds with appropriate adjustments in breathing rate and heart rate.
What changes carbon dioxide gas back into carbon in a solid form?
the cold air can change the carbon dioxide gas to a solid
Which increase in atmospheric carbon dioxide contributes to global climate change?
Any increase in atmospheric carbon dioxide contributes to global climate change.
Is carbon dioxide a reversable or irreversible reaction?
This is a reversible change as it involves a change in the state of a substance. Also, by applying pressure and lowering the temperature, gases carbon dioxide can be converted back into dry ice.
