ATAMSBLAST DIGITAL AGENDA 10 – 11 College Prep Chemistry B KAUFFMAN6 – 9 February 2012 DO NOW: M: Download the three homework assignments that were due last week and the six step problem solving procedure PDF. Today is a day for you to catch up on your missing assignments. Solve: How many grams of CaCl 2 · 2H 2 O are needed to produce 3.5 L of a 0.1 M solution? W: Log in to Achieve3000. On the left hand side of your screen, click Mail. Read the from me and then respond to it, following the instructions given. Th: Put everything away off of your desk except for something to write with and your calculator. Today is the unit exam over solutions. California Standards: Std 6a: Solute vs Solvent Std 6c: Vars affecting rate of solution Std 6b: Solution Process Std 6d: Units of solutions Std IE: Expt & Investigation Essential Questions: What is a solution and what are the properties of solutions? How do we compare solutions? What variables affect solubility and the rate of solution? LEARNING OBJECTIVES FOR STUDENTS: Given: Compass learning activities, information and practice packet, a laboratory procedure, and direct instruction the learner will: accurately describe solutions, their properties, and conduct calculations related to solutions by: analyzing one solution important to their day to day lives, solving problems relative solutions using the procedures outlined in class and showing their work, and answering questions on solutions and their properties, and completing a unit exam on solutions concepts.

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. Direct Instruction: Ask questions about the concentration packets Notes on molarity problems Demonstration Collaborative Station: As a group, work through the packet on Concentrations (posted on HW page). Complete your lab write-ups and prelabs for this week.

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.

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.
