Chemical Reactions - Standards
California Science Content Standards
Standard 5: Chemical reactions are processes in which atoms are rearranged into different combinations of molecules.
- 5a: Students know reactant atoms and molecules interact to form products with different chemical properties.
- 5b: Students know the idea of atoms explains the conservation of matter. In chemical reactions the number of atoms stays the same no matter how they are arranged, so their total mass stays the same.
- 5c: Students know chemical reactions usually liberate heat or absorb heat.
