Is bleach a chemical reaction?
Yes, bleach is a chemical reaction. It contains sodium hypochlorite, which reacts with water to produce hypochlorous acid. This acid is responsible for the bleaching and disinfecting properties of bleach.
Is bleaching your hair physical or chemical property?
Bleaching your hair is a chemical process, not a physical property. The chemicals in hair bleach work to break down the natural pigments in your hair, resulting in a lighter color. This change is due to a chemical reaction rather than a physical characteristic of the hair itself.
Is bleaching tiles a chemical change?
Bleaching your hair is a chemical change. The bleach reacts in hair, removing the color in an irreversible chemical reaction. There is no way to reverse the bleaching. Bleaching your hair also makes a new substance, when you do bleach your hair it is permanent.
Is bleaching hair chemical or physical?
Bleaching hair is a chemical process. It involves the use of chemical compounds, like hydrogen peroxide, to break down and remove the natural pigment in the hair shaft. This changes the hair color by lightening it.
What is an observable reaction?
An observable reaction is a change that can be measured, detected, or witnessed during a chemical or physical process. This can include changes in color, temperature, precipitation, gas formation, or the release of light or sound. It provides evidence that a chemical reaction or a physical change has occurred.

What chemical reaction takes place when bleaching a stain?
Bleaching stains typically involves the chemical reaction of the bleach (usually chlorine-based compounds like sodium hypochlorite) breaking down the chromophores in the stain molecules. This process disrupts the bonds that give the stains their color, effectively decolorizing them.

Is bleaching a stain out of a article clothing a chemical change or a physical change?
Bleaching is done by oxidising chemicals like hypochlorite (bleaching powder) or peroxides. So it is a chemical change(called reaction): the stain is not (only) dissolved, but (rather) broken down to colorless molecules.Additions to this answer are on the discussion area.

If burning sugar is a chemical reaction can you give me an evidence?
One evidence that burning sugar is a chemical reaction is the production of heat and light during the process. This indicates a change in the chemical composition of the sugar molecules as they react with oxygen in the air, releasing energy in the form of heat and light. Additionally, the formation of new substances such as carbon dioxide and water from the sugar molecules further supports the occurrence of a chemical reaction.
Is a chemical reaction?
A chemical reaction is a process that leads to the transformation of one set of chemical substances to another.
Is there evidence of a chemical reaction when bubbles form on heated water?
Bubbles forming on heated water are usually due to the process of water vaporization rather than a chemical reaction. When water is heated, the molecules gain energy and move faster, eventually reaching a point where they break free from the liquid surface and form bubbles of water vapor. This phase change is a physical process, not a chemical reaction.
How is the process of converting kiwi in plastic-ware evidence of a chemical reaction?
It gives evidence of a chemical reaction because it's molecules have changed to make something new also because it looks very different from how it looked before.
What is an observable reaction?
An observable reaction is a change that can be measured, detected, or witnessed during a chemical or physical process. This can include changes in color, temperature, precipitation, gas formation, or the release of light or sound. It provides evidence that a chemical reaction or a physical change has occurred.
What is an enzyme(what does it do for a chemical reaction)?
the purpose is to accelerate the process of the reaction...
