When iron is heated until it turns red will the color show a chemical change has occurred?
Ashleedevon
Iron turning red happens when it is burnt and it is not called as rusting because rusting happens when iron material has not been used for a long time.Iron turning red is a chemical change because change in color is also considered as a chemical change.

When you dye your hair is that physical change or chemical change?
Yes it is a chemical change because color change is an observed change that a chemical change has occurred. So you are very much right. :)
When iron is heated until it turns red the color change shows that a chemical change has occured?
False.
What clues can you use to identify a chemical change?
Characteristics of a chemical change can include a temperature change, a color change, the production of bubbles, the production of a precipitate, and a smell.
Why do elements change color when mixed with others elements?
Color change indicates a chemical reaction has occurred. The mixture of elements has different chemical properties than the original individual elements.

When paper changes from yellow to brown in sunlight what type of change occurred?
A chemical change. Color change is a good indicator of a chemical change.

False.
How can you be certain that a chemical change has occurred?
Signs of chemical reactions may be: - Gas release - Formation of a precipitate - Change of color - Change of odor - Change of pH - Change of aspect - Change of viscosity - Change of the temperature - Visible formation of new compounds
How will you know that a chemical reaction has occurred?
Some indicators of a chemical reaction are:- change of color- change of odor- release of a gas- change of the temperature- change of the viscosity- formation of a precipitate- change of general appearance- possible explosion- possible chemiluminescence- formation of new compounds
Is a common sign that a chemical change has occurred?
A change in pH or conductivity will always hint to a chemical change. Also less technical signs can be a change in volume or color
