Burning
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.
A chemical change in oxygen occurs when it reacts with another substance to form new compounds. For example, when oxygen reacts with iron, it forms iron oxide (rust), which is a different chemical compound than oxygen. This process involves breaking and forming chemical bonds.
Rusting of a screw is a chemical change. It involves a chemical reaction between the iron in the screw and oxygen in the air to form iron oxide (rust).
It is a chemical property, as it involves a 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.
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.
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.
NO its a chemical change for it can't be reversed

Oxidizing is a chemical change, as it involves a substance reacting with oxygen to form new compounds with different properties. In contrast, physical changes do not alter the chemical composition of a substance.

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.
The change of oxygen from a gas to a liquid is a physical change, as the substance itself remains the same chemically. The physical change involves altering the state of the molecules without changing their chemical composition.
When sulfur combines with oxygen, it undergoes a chemical reaction to form sulfur dioxide. This is a chemical property of sulfur because it involves a change in the chemical composition of the substance.
Chemical change. Burning anything will create a chemical change. Burning involves taking the object/substance being burnt + oxygen to produce water and carbon dioxide.
The formation of an oxide when sodium metal is heated with oxygen is a chemical change. This is because a new substance (sodium oxide) with different chemical properties is formed due to a chemical reaction between sodium and oxygen. It involves the rearrangement of atoms at a molecular level.
