Discover fascinating chemical reaction facts, from glow-in-the-dark reactions to everyday kitchen chemistry. Explore surprising lesser-known insights about chemical reactions that shape our world.

Essential Chemical Reaction Facts

1. Chemical reactions occur when bonds between atoms break or form, creating new substances with different properties than the original reactants.
2. The Law of Conservation of Mass states that matter cannot be created or destroyed in a chemical reaction – the total mass of reactants always equals the mass of products.
