Is it a chemical or physical change when oxygen is incorporated into hemoglobin to bring it to the cells?
This is a chemical change. When oxygen binds to hemoglobin, it forms a new compound with a different chemical composition. This process involves breaking and forming chemical bonds.
Is a silver teapot turning black a chemical or physical change?
It is a chemical change but it can be reversed since that cahnge is only on the surface. It is merely an oxidization that occurs when silver is exposed to oxygen and has no contact with oil (which blocks the pores of the metal from reacting with oxygen).
What is a chemical change that involves oxygen?
The rusting of iron is a chemical change that involves oxygen. When iron reacts with oxygen in the presence of water, iron oxide (rust) is formed. This process is an example of oxidation.
Is burning alcohol in oxygen a physical or chemical change?
Burning alcohol in oxygen is a chemical change because it involves a chemical reaction that produces new substances with different properties. The alcohol (ethanol) reacts with oxygen to form carbon dioxide and water vapor, which are completely different from the original alcohol molecules.
Is separating water into oxygen and hydrogen an example of a change?
Yes, separating water into oxygen and hydrogen is an example of a chemical change. It involves breaking the bonds between the hydrogen and oxygen atoms in water molecules, resulting in the formation of new substances with different properties (oxygen and hydrogen gas).
Is forming ozone from oxygen a chemical change?
Putting oxygen in tanks (under pressure) is a physical change, not a chemical change. The chemical nature of the oxygen has not been altered, and it is possible to recover the original substance, thus it is not a chemical change.
The chemical change of glucose and oxygen into energy -?
The chemical change of glucose and oxygen into energy is called fermentation.
Is combining hydrogen and oxygen a physical change or a chemical change?
This is a chemical change.
The chemical change of the sun's energy into glucose and oxygen-?
Photosynthesis is the chemical change of the suns energy into glucose and oxygen.
Is heating mercuric oxide a physical or chemical change?
This is a chemical reaction; oxygen is released.
If leaves producing oxygen a chemical or physical change?
That would be a chemical change.
Is oxygen a chemical change or a physical?
Oxygen is a chemical element, so its presence does not involve a chemical change. It undergoes physical changes such as changes in state (gas to liquid) based on temperature and pressure.
Is oxygen gas a chemical change?
Oxygen gas is not a change of any sort. It is an element.
When oxygen is liquefied is it a physical or chemical change?
Physical because it is still Oxygen. A chemical change results in a chemical equation and thus a new substance. No new substance = no chemical change. Liquefaction is a physical property.
Is Oxygen and hydrogen combining to form water physical or chemical change?
This is a chemical change.
Is burns in the presence of oxygen physical or chemical change?
The process of burning in the presence of oxygen is that of a chemical change. It is a chemical change and not a physical change because the prodects do not have the same properties as the reactants.
Is a sugars and oxygen in the muscles producing lactic acid physical or chemical change?
This is a chemical change.
