<p>Chemistry Ch. 2 Notes Outline and Key Concepts Name</p><p>1. I understand the differences, and the connections between Energy and Matter 2. I can apply the Laws of Conservation to real world scenarios, and predict and interpret their results. 3. I can identify the 5 phases of matter, and describe how the motion of their particles results in their properties 4. I can identify and differentiate between elements, compounds, homogeneous mixtures and heterogeneous mixtures. 5. I can recognize the difference between chemical and physical changes and properties 6. I can perform calculations that support the Laws of Conservation, including percent composition.</p><p>Define matter. </p><p>What is the Law of Conservation of Matter? </p><p>What is the Law of Conservation of Energy?</p><p>Are there any “exceptions” to the rule? Be specific.</p><p>KC #2 Explain why all samples of a given substance have the same intensive properties.</p><p>KC# 3 What are the five (5) phases of matter? Include their motion of molecules, how much relative Energy they have, and relate absolute zero to the proper phase, including its temperature.</p><p>What does it mean to be a pure substance?</p><p>What is an element? Give an example </p><p>What is a compound? Give an example</p><p>KC #20 How is a compound different than an element?</p><p>KC #22 What re chemical symbols and chemical formulas used for?</p><p>KC #11 What is a homogeneous mixture? Example?</p><p>What is a heterogeneous mixture? Example</p><p>KC #21 How can you distinguish a pure substance from a mixture?</p><p>What are the a processes you can do to separate mixtures? </p><p>KC #31 What is the main difference between physical changes and chemical changes?</p><p>KC #28 How does a chemical change affect the composition of matter?</p><p>KC #29 Name four possible clues that a chemical change has taken place.</p><p>KC #30 In a chemical reaction, how does the mass of the reactants compare with the mass of the products?</p><p>What processes are chemical changes (can turn compounds into elements or vice versa)?</p>
