- 1. Unit 1 Lesson 4 Pure Substances and Mixtures 1) I can define mixture, solute, solvent and solution 2) I can classify elements and compounds as two types of pure substances
- 4. Solvent : is the substance that dissolves other substances. Ex: water Solute: is the substance to be dissolved Ex: sugar Mixture : water + sugar Parts of the mixture
- 5. A mixture is a combination of two or more substances that are combined physically but not chemically. Mixtures are not pure substances and do not have definite properties. Substances within a mixture keep their identities and individual properties. Mixtures can be separated by physical changes, although some mixtures are difficult to separate. Magnets, centrifuges, filters, and other materials can be used to separate mixtures. What are mixtures
- 6. A suspension is a heterogeneous mixture.A solution is a homogeneous mixture
- 7. What is the type of mixture?
- 9. A pure substance is a substance with definite physical and chemical properties. Pure substances are made up of just one type of particle. Elements and compounds are pure substances. Pure substance
- 10. Physical changes such as melting, freezing, cutting, or smashing do not change the identity of pure substances. When a pure substance undergoes a chemical change, it is no longer that same substance. What are pure substances?
- 11. An atom is the smallest unit of an element that maintains the properties of that element. Substances are classified as elements, compounds, and mixtures Basic unit of matter
- 12. Is water an element, a compound, or a mixture?
- 13. 3 atoms: 2 hydrogen atoms -------- same element (Hydrogen) Compound 1 oxygen atom ------- one element (oxygen)
- 17. An element is made of only one kind of atom. A compound is made up of different kinds of atoms that are chemically combined. A mixture contains a variety of elements and compounds that are not chemically combined. How can matter be classified?
