Two common examples are photosynthesis and cellular respiration.
Bleach
no, it happens naturally
chemical change
A smelly sock is a chemical change because the release of odor is a result of chemical reactions occurring within the sock.
solid,liquid,or gas
Manual manipulation is to interfere with a naturally occurring process and change it to benefit our needs
If there is no chemical reaction occurring in the solution as a result of heating then this scenario constitutes a phase change.
The biggest advantage of chemical change is life. All organisms are alive because of the sum total of all the chemical reactions occurring in their cells.
Freckles is a naturally occurring pigment change in the skin. They didn't need to be invented by anyone.
i would think physical, unless there is a chemical change occurring..... :)
Mixing is not itself a chemical change. There could be one occurring as a result, but nothing you described indicated any kind of chemical change.
The net ionic equation shows the chemical species that are directly involved in the reaction, excluding spectator ions that do not participate in the actual chemical change. It focuses on the ions or compounds that undergo a change in oxidation state or bonding during the reaction, providing a clearer picture of the essential chemical processes occurring.
