Lesson details
Key learning points
- Reactants are the chemicals that react in a chemical reaction.
- Products are the chemicals that are formed in a chemical reaction.
- The products and reactants in a chemical reaction contain exactly the same atoms.
- The atoms in the products of a chemical reaction are bonded differently to the same atoms in the reactants.
Keywords
Reactants - Reactants are the elements or compounds before a reaction takes place. Reactants are found on the left-hand side of a chemical equation.
Products - Products are the elements or compounds that are formed after a reaction has taken place. Products are found on the right-hand side of a chemical equation.
Common misconception
The idea that atoms can be created or destroyed when new products are formed.
Matter cannot be created or destroyed, only arranged differently to be formed into new products.
