A chemical reaction is when the molecular structure of an arrangement of atoms has been reconfigured into a new and different molecular structure, or to put plainly, one or multiple things have changed into another, such as when mixing Sodium and Chloride together to make table salt.
Color is created when white light bounces off an object. White light is bounced off a white T-shirt, primarily yellow light is bounced off a yellow sunflower (while the other colors are being absorbed), and black is absorbing all of the white light when it hits the black road (this is the main reason why roads are hot in the summer, because it's absorbing the heat along with the light). It's the arrangement of the atoms and how the light bounces off them that determines the color of the structure.
So when color changes in a Chemical Reaction, it just means that the old molecular structure has changed into a new one insomuch that it is now radiating (or bouncing off) a different spectrum of light.

Does a chemical reaction change color?
As the electrons change orbits, they change energy levels. The energy is released into photons - which is the light of a fire. When different elements oxidize, they give off different energies - thus different colors.
What does that mean when BTB solution turns yellow?
A yellow color in BTB solution usually indicates a change in pH, typically the solution becoming more acidic. This change in color can be used to monitor chemical reactions, particularly those that involve the release of protons or acidic substances.
How do you tell if something is a chemical change?
I assume you mean how to write out a chemical reaction. Here is an example: Na+ + Cl- = NaCl For more examples you should refer to any High School level Chemistry textbook. If you mean how does a chem reaction look while you are observing it, lots of things can happen. Color change, light, phase transistions, etc...
Why does a colour change not always mean that a chemical change has taken place?
The only example I can think of here is kind of weak; if you dissolve anhydrous copper sulfate in water, it turns blue. Evaporate the water completely, and you'll get the anhydrous copper sulfate back, and it won't be nearly as blue as the solution was.
What kind of change is ripening of fruit?
The ripening of fruit is a physiological change that involves the softening, color change, and development of flavors in the fruit as it matures. This process is triggered by ethylene gas and various enzymatic reactions that break down starches into sugars, making the fruit sweeter and more palatable for consumption.
What mean to be analitical?
chemical reactions
Undergo no chemical change during a chemical reaction?
A catalyst doesn't undergo a chemical change during a chemical reaction.
How does chameleon camouflage himself?
Chameleons use their cell structure in their skin to change color. This does not mean that if you put a chameleon onto a red surface that it will change red in color. chameleons can only change a few different colours, mostly used dependant on the mood of the lizard. It does how ever try to blend in as much as possible. So to camouflage it's self it uses it's cells and chemical reactions in the skin to change the color in it's skin.
Does a chemical reaction change color?
As the electrons change orbits, they change energy levels. The energy is released into photons - which is the light of a fire. When different elements oxidize, they give off different energies - thus different colors.
What would it mean if the change in mass is negative?
A negative change in mass means that the object has lost mass. It could be due to factors such as evaporation, chemical reactions, or loss of particles.
What does evidence chemical change mean?
Evidence of a chemical change refers to observable signs that a chemical reaction has occurred. This can include color change, formation of gas or precipitate, temperature change, or production of light. These changes indicate that the substances involved in the reaction have undergone a chemical transformation at the molecular level.
What type of change that produces a new substance?
If you mean changing one element into another, like uranium 238 into plutonium 239, which happens in nuclear reactors, the word is 'transmutation'. Otherwise many chemical reactions form new substances, without the elements involved changing, and these would be called 'chemical reactions'.
Is the change of identity a physical or chemical property?
If you mean a change in chemical identity, that would be a chemical change.
How are physical and chemical reactions different?
Physical reactions mean that the substance hasn't been altered in terms of its composition. For example, liquid water turning into an ice cube is a physical change. It is still H2O - just different form. However, burning paper is chemical change, since ash + H2O + CO2 is not paper.
Do chemical changes and chemical reactions differ?
No. They are just two different terms that mean the same thing.

A yellow color in BTB solution usually indicates a change in pH, typically the solution becoming more acidic. This change in color can be used to monitor chemical reactions, particularly those that involve the release of protons or acidic substances.
