Must new substances be formed when you observe a chemical property? My answer is no because you are just observing. There is no reaction taking place. I don't know if my answer is correct.
Oh thank you anyway
if there is no reaction...what are you observing?
Physical changes vs. Chemical Changes
Chemical changes - a reaction does occur. Changing Hydrogen and Oxygen into water.
Physical Change would be changing water into ice. It is still water just in a different form.
the question specifies "chemical property"
Your answer is correct. When you observe a chemical property, you are simply studying a characteristic of a substance without any reaction or formation of new substances taking place. Chemical properties are inherent properties of a substance that describe how it interacts and reacts with other substances. They can include things like reactivity, flammability, toxicity, and acidity.
To verify your answer, you can think about the definition of a chemical property. If no new substances are formed during the observation, it implies that there are no chemical changes occurring. Chemical changes involve the rearrangement of atoms or molecules to form new substances with different properties.
It's important to distinguish between chemical and physical properties. Physical properties, such as color, density, and boiling point, can be observed without any chemical changes occurring as well. However, chemical properties specifically refer to the ability of a substance to undergo chemical reactions and form new substances.
