A chemical property is any of a material's properties that becomes evident during a chemical reaction; that is, any quality that can be established only by changing a substance's chemical identity. Examples of chemical properties include reactivity, flammability and oxidation states. How to use chemical in a sentence. Some chemical changes are a little more difficult to spot, like when a nail rusts. However, for many properties within the scope of physical chemistry, and other disciplines at the boundary between chemistry and physics, the distinction may be a matter of researcher's perspective.

Scientists can determine if a chemical change has occurred by asking this question: Was the substance formed present before?
Some major chemical properties include flammability, toxicity, heat of combustion, pH value, rate of radioactive decay, and chemical stability. A chemical change can produce amazing explosions, like fireworks. PHYSICAL CHANGES EPISODE!Anytime a new substance is made, a chemical change takes place. I started the video subscription in May and used them as a review before the state test, which I know contributed to 100% of my class passing the state test.
