definitions
Reactant: A starting substance in a chemical reaction
Mixture: A physical blend of two or more components
Phase: Part of a sample having uniform composition and properties.
Heterogeneous: Not uniform in composition
Product: A substance formed in a chemical reaction
Mass: Amount of matter an object contains.
Homogeneous: Describe mixture with a uniform composition
Reaction: Process in which substances are charged into different by chemical means.
Element: Substance that cannot be changed into simpler substance by chemical means.
Compound: Composed of two or more substances chemically combined in a fix proportion.
Chemical Properties Examples: Rust
Physical Properties: Smell, Touch, Taste
Intensive Property: Does not depend on the amount of matter. Depend on the type of matter.
