If a substance changes color what has most likely happened chemical or physical change?
Very probable a chemical change; but also physical changes can be the cause.
What is evidence that a chemical change has happened?
Evidence of a chemical change includes a change in color, formation of a precipitate, evolution of gas bubbles, or a change in temperature. Additionally, if the substance cannot be easily reversed back to its original form, it is likely a chemical change has occurred.
What is the most likely sign that a chemical change has happened?
The most likely sign that a chemical change has occurred is the formation of a new substance with different properties. This can include color changes, formation of a precipitate, evolution of gas, or changes in temperature.
When paper turn yellow brown upon exposure to sun light what type of change is likely taking place?
The paper is likely undergoing a chemical change called photodegradation, where the molecules in the paper are breaking down due to the energy from sunlight. This can cause the paper to change color and become brittle over time.
Which chemical change is most likely to involve bubbling or an odor?
A chemical change that is most likely to involve bubbling or an odor is the reaction between an acid and a base to produce water and a salt. For example, mixing hydrochloric acid (HCl) with sodium hydroxide (NaOH) produces water and sodium chloride (NaCl), with bubbling and a characteristic odor of the products.

Is burning a bagel a physical or chemical change?
Burning is most likely chemical
If graham crackers are crushed for a pie crust is that likely caused by a chemical reacion or chemical change?
Crushing the graham crackers is a physical change, not chemical. *Chemical reactions and chemical changes are the same thing.
Is mostly likely a chemical change salt dissolving in water or a match burning?
A match burning is a chemical change. Salt dissolving in water is a physical change.
