Chemical Reactions
Fun Facts
- Testing the properties of magnetism, flammability, electricity, density, and odor before and after a chemical reaction help determine if a new substance was formed.
- Lighting a gas grill requires a chemical reaction in which atoms are rearranged.
- When iron combines with oxygen in a chemical reaction, it is no longer flammable because its properties have changed.
Why Do We Need To Know About Chemical Reaction
Learning about chemical reactions helps you understand the world better. Scientists use these reactions to make new materials and medicines. This knowledge is important for science and is used in real life too.
Chemical reactions are behind everything from how our food is digested to how rockets fly. They help create new things like bendy solar panels and make rocket fuel better. Knowing about chemical reactions helps people like chemical engineers and material scientists fix problems and come up with new ideas, showing how chemistry is used to solve problems and make new things.
