Dissolution of gases in water is a physical change.
it would be a chemical reaction mArKe ^_^
One way to remove oxygen from water is through a process called deoxygenation, which involves using a chemical or physical method to strip the oxygen molecules from the water. This can be done through techniques such as boiling, purging with an inert gas like nitrogen, or using chemical agents that react with the oxygen to remove it from the water.
The element's symbols are N and O, the gaseous diatomic molecules are represented by N2 and O2 .
This is a chemical change.
Breaking water into the component parts of hydrogen and oxygen is a CHEMICAL change.
Chemical change; bonds are broken when water decomposes into hydrogen and oxygen.
the elements found in nitrogen, hydrogen and oxygen
This is a chemical reaction.
Water: Hydrogen and Oxygen (H2O) or Table Salt: Nitrogen and Cholrine (NaCl)
Because molecules have other chemical and physical properties than the containing atoms !
Water is a compound made of hydrogen and oxygen. Nitrogen and oxygen are elements on their own.
The process of leaves producing oxygen is a physical and chemical process. It involves photosynthesis which is a chemical reaction that converts sunlight, water, and carbon dioxide into glucose and oxygen. This process occurs in the chloroplasts of plant cells.
