24. Chapter 1. (L1)-Introduction • It is Matter That Matters -Things are different -Things are changing good changes and changes we want healthy food, medicine, materials, clean water bad changes and changes we try to avoid

25. Chapter 1. (L1)-Introduction • It is Matter That Matters Now, we can’t help asking some questions: -Why are things different? -What make things differ from each other? -Why are things changing? -What drive things changing?

26. Chapter 1. (L1)-Introduction • Basic Theme of Chemistry Let money talk How to make changes? How many basic money elements? Answer: coins (p, n, d, q, dl) bills (1, 2, 5, 10, 20, 50, 100, 200)

27. Music: A keyboard Instrument

28. Chapter 1. (L1)-Introduction • Basic Theme of Chemistry Dreams by Langston Hughes Hold fast to dreams For if dreams die Life is a broken-winged bird That cannot fly Hold fast to dreams For when dreams go Life is a barren field Frozen with snow

29. Chapter 1. (L1)-Introduction • Basic Theme of Chemistry Ozone Chemistryby Sidney Chapman O2 + hv = O + O O + O2 = O3 O3 + hv = O + O2 O3 + O = O2 + O2

30. Chapter 1. (L1)-Introduction • Basic Theme of Chemistry Something happened in Coke CO2 + H2O = H2CO3 H2CO3 = H+ + HCO3- HCO3- = H+ + CO32-

31. Chapter 1. (L1)-Introduction • Basic Theme of Chemistry A basic theme is emerging: We can use some basic elements to compose various things, such as in the cases of money, music (keyboard), and language. Chemistry is a language.

32. Chapter 1. (L1)-Introduction • Basic Theme of Chemistry For a language, we can ask these questions: What are the basic letters of English? How do the letters become the language of English? (letter, words, sentences, paragraph, and so on) What is the grammar (rules and laws)?

33. Chapter 1. (L1)-Introduction • Basic Theme of Chemistry Likewise, we can ask the similar questions about matter: What are the basic elements for matter? How can we determine what these basic elements are? How small are they? How do these elements make various things? How can we use these elements to explain and describe the changes of things?

34. Chapter 1. (L1)-Introduction • Basic Theme of Chemistry Chemistry is the science to answer these questions. The answers are not arbitrary, but have to be given in a scientific way.

35. Chapter 1. (L1)-Introduction • Basic Theme of Chemistry In this course, we will learn how chemistry answers these questions, and explains the different things and their changes around us. And, also, we will learn the scientific way to answer these questions. In other words, we will learn the language of chemistry as science.
