Why Is Color Change A Chemical Reaction? When two or more substances combine, they create one or more new substances, which sometimes have different molecular structures from the original substances, meaning they absorb and radiate light in different ways, leading to a color change. Is color change evidence of a chemical reaction? Yes; new substances
Which Of The Following Is The Best Evidence For A Chemical Reaction? Best evidence for a chemical reaction is a formation of a new substance. What is the best evidence for a chemical reaction? Color Change. Production of an odor. Change of Temperature. Evolution of a gas (formation of bubbles) Precipitate (formation of a solid)
Which Of The Following Is An Example Of A Physical Change? Examples of chemical changes are burning, cooking, rusting, and rotting.

When A Substance Undergoes A Change A New Substance With Different Properties Is Created? Chemical changes occur when bonds are broken and/or formed between molecules or atoms. This means that one substance with a certain set of properties (such as melting point, color, taste, etc) is turned into a different substance with different properties. Is
Which Real World Scenarios Represent Physical Changes? Examples of physical change include changes in the size or shape of matter. Changes of state—for example, from solid to liquid or from liquid to gas—are also physical changes. Some of the processes that cause physical changes include cutting, bending, dissolving, freezing, boiling, and melting. Which is an
