Made of elements in a specific ratio
that are always the same
Can only be separated by
chemical means, not physically
H2O
NaCl
CO2

5. Mixtures
A combination of two or more pure substances that are not chemically combined.
No chemical change takes place

39. Is a Glow Stick Compound or Mixture?
How it works:
Glow sticks give off light when two solutions are mixed.
The sticks consist of a small, brittle container within a flexible outer container. Each container holds a unique solution.
When the outer container is flexed, the inner container breaks, allowing the solutions to combine, causing the necessary chemical reaction. After breaking, the tube is shaken to thoroughly mix the two components
