1. 1Zumdahl's Introductory Chemistry - Chapter 1 Chemistry: An Introduction Chapter 1

2. 2Zumdahl's Introductory Chemistry - Chapter 1 Why is Chemistry Important? In Our Daily Lives  New Materials  New Pharmaceuticals  New Energy Sources  Food Supplies  Can you think of others?

3. 3Zumdahl's Introductory Chemistry - Chapter 1 Why is Chemistry Important? In Your Education  Help you learn to Gather and Organize Information Qualitative and Quantitative  Help you learn to find Patterns in Information  Help you learn to Analyze Complex Systems  Help you develop skills to Predict Future Events based on Patterns of Behavior  Help you develop Problem-Solving Skills Systematic Approach

4. 4Zumdahl's Introductory Chemistry - Chapter 1 What is Chemistry? The science that deals with the materials of the universe and the changes these materials undergo The Central Science  Understanding most other fields of science requires an understanding of Chemistry

5. 5Zumdahl's Introductory Chemistry - Chapter 1 Solving Problems Using a Scientific Approach Define the Problem Gather Information  Facts  Observations Propose Solutions Organize Information and look for Patterns Hypotheses

6. 6Zumdahl's Introductory Chemistry - Chapter 1 Evaluate your Proposed Solutions Test your Patterns by using them to Predict What Will Happen Experiments Solving Problems Using a Scientific Approach

7. 7Zumdahl's Introductory Chemistry - Chapter 1 The Scientific Method A process of studying natural phenomena that involves making observations, forming laws and theories, and testing theories by experimentation

8. 8Zumdahl's Introductory Chemistry - Chapter 1 The Scientific Method Make Observations  Qualitative  Descriptions  Quantitative  Measurements Formulate Hypotheses  Possible Explanations for Observed Characteristics or Behaviors Perform Experiments  Test Hypothesis

9. 9Zumdahl's Introductory Chemistry - Chapter 1 The Scientific Method Repeat the process until we get a well-tested explanation Theory  a set of assumptions put forth to explain some aspect of the observed behavior of matter  May need to be modified or discarded as new information (observations) becomes known

10. 10Zumdahl's Introductory Chemistry - Chapter 1 The Scientific Method While Experimenting we may Observe the Same Behavior all the time, and therefore be able to Predict this Behavior will Always Occur in the Future Law  a generally observed behavior  Without explanation as to why the behavior occurs!

11. 11Zumdahl's Introductory Chemistry - Chapter 1 The Difference Between a Theory and a Law Laws predict what will happen Theories explain why something happens  Which will also allow you to predict what will happen!

12. 12Zumdahl's Introductory Chemistry - Chapter 1 The Best Approach to Learning Chemistry Learn the Vocabulary of Chemistry  Definitions of Terms  How Common Vocabulary is Applied to Chemistry Memorize Important Information  Names, Formulas and Charges of Polyatomic Ions  Solubility Rules Learn and Practice Processes  Systematic Names and Formulas  Dimensional Analysis Do the Questions and Exercises at the End of the Chapter to Test your Understanding and help you See the Patterns
