Classifying Matter: Anything that has mass and volume Organizing the Knowledge of Substances

Classifying Matter: Anything that has mass and volume Organizing the Knowledge of Substances

Homogeneous Mixture: Solutions Solute: A substance that is dissolved in something Solvent: Any substance

Homogeneous Mixture: Solutions Solute: A substance that is dissolved in something Solvent: Any substance that dissolves a solute Solution: Homogeneous mixture of dissolved substances containing at least one solvent and one solute Eg. Salt water Water is a solvent Salt is a solute

Elements versus Compounds Substance Empirical Definition Theoretical Definition Examples Elements Can’t be broken down

Elements versus Compounds Substance Empirical Definition Theoretical Definition Examples Elements Can’t be broken down further Made of one kind of atom K Mg O 2 Decomposed Made of more chemically by than one kind of heat or electricity atom H 2 O Na. Cl Compound

Solutions compared to Elements and Compounds The Relationship between Solutions, Elements, and Compounds :

Solutions compared to Elements and Compounds The Relationship between Solutions, Elements, and Compounds : - Solutions contain more then one compound or element. These compounds and elements are uniformly dispersed throughout the solution. Eg. HCl + H 20 HCl (compound) (Compound) (solution) - Pure substances can be written as chemical formulas
