During a chemical reaction, two or more reactants come together and mix it up to make new products. It's like when you mix up some ingredients to make a tasty cake, except with chemicals. The reactants break their old bonds and make new ones to form the products. It's like they're having a big party and swapping dance partners!
In 3–5 sentences, describe the difference between a chemical property and a physical property.
A chemical property is something that describes how a substance reacts with other substances to make new stuff, like if it rusts or burns. It's all about what happens when you mix it with other things. A physical property, on the other hand, is all about how the substance looks or feels, like its color, shape, or texture. It's more about what you can see or touch without changing the substance itself. So, chemical properties tell us how substances behave, while physical properties tell us how they look or feel.
