a change in the color of a solution is a sign that\n\na. a physical change has just occurred.\n\nb. organic chemicals are present.\n\nc. a chemical change is taking place.\n\nd. oxygen is present.
Answer
Brief Explanations:
A color - change in a solution is often an indicator of a chemical reaction. Chemical reactions involve the breaking and forming of chemical bonds, which can lead to new substances with different properties, including color. Physical changes do not usually cause color changes (except in some cases related to light - scattering which is not the main case here). The presence of organic chemicals or oxygen alone does not necessarily cause a color change in a solution.
Answer:
C. a chemical change is taking place.
