  2. Collaborative Station: • As a group, work through the packet on Concentrations (posted on HW page). • Complete your lab write-ups and prelabsfor this week. Direct Instruction: • Ask questions about the concentration packets • Notes on molarity problems • Demonstration Individual Instruction: • Catch up on your compass learning quizzes. • Read through the packets from the collaborative station and copy the flow charts for solving each type of concentration problem.

  3. Classification of Matter • Matter: anything that takes up space and has mass • Pure substance: only one type of matter is present—it is the same throughout • Element: pure substance that cannot be broken down into smaller components by non-nuclear methods • Compound: composed of two or more elements in a fixed ratio and (arrangement of atoms when it is solid) • Mixture: Two or more pure substances added together • Homogeneous: same throughout (homogenized—grind up the solid particles into small enough parts, the milk is the same throughout) • Heterogeneous: 2 different phases. • Solutions: made up of a solvent and solute. The solvent is the compound that is present in the greatest amount. The solute is the compound that is present in lesser amounts. Alloys: solution made of two or more metals.

  4. Classification of Matter • Matter: anything that takes up space and has a resistance to a change in motion (inertia or mass) • Pure substance: something that is made up of only one type of matter. • Elements: smallest building blocks of matter that cannot be divided further without nuclear reactions • Compound: combination of 2+ elements that are arranged in a certain order by fixed ratios. • Mixture: combination of two or more pure substances that can be separated by non-chemical means. • Homogeneous mixture: the same throughout (homogenized milk: chop the fat and proteins up into small particles that can be evenly dispersed in the milk. • Solution: two or more compounds mixed uniformly throughout. The component in the largest amount is called the solvent. The component in the lesser amount is called the solute. Diet Pepsi: solvent: water; solutes: carbon dioxide, caramel color, aspartame, phosphoric acid, potassium benzoate, caffeine, citric acid, and natural flavors) • Alloy: one or more elements or compounds dissolved in a solid metal as the solvent. • Heterogeneous mixture: 2+ different regions or phases within the mixture.
