Heterogeneous and homogenous
What is a homogeneous mixture
Mixture with substances completely mixed together and cannot be distinguished
What is a heterogeneous mixture
Substance with particles large enough to tell the difference between
What are physical properties
Characteristics that can be observed without changing the chemical composition
What are extensive properties
