Study 3 hours a week for every hour of credit This is a 4 credit-hour class So? So? 12 hours/week !! 12 27 problems / 12 hours = 2.25 prob/hr Chapter 1 Matter and Measurement • 1.1 The Study of Chemistry • Chemistry is the study of properties of Chemistry matter and the changes it undergoes. matter • What is matter ? What matter • Has mass; occupies space; made up of Has ~100 elements; elements combine to form molecules (compounds if they contain more than one element) more Chapter 1 Matter and Measurement • Chemistry is about bonding Chemistry between atoms! between • Bonding is about electrons! • So chemistry is about electrons • The number of electrons is determined by the element determined • Let’s look at elements Let’s • The Periodic Table Elements and compounds • Compounds contain more than one Compounds element. They always have the same composition, regardless of source (law of constant composition; law of definite proportions). proportions). Classifications of Matter • Make a list of things (and their parts) Make found in the classroom. Classify these as found • • • • solid, liquid, or gas solid, homogeneous or heterogeneous pure substances and mixtures elements or compounds • How do you place them into these How classifications? classifications? Classifications of Matter • Matter can be placed in these classes both Matter on the basis of macroscopic properties, and by considering their atomic/molecular distributions. distributions. Classification of Matter Method to classify matter Classify • • • • mixtures pure substances elements compounds Physical and Chemical Changes • Is this a Is physical or a chemical change? change? • Explain your Explain reasoning. reasoning. Units of Measurement • What is the size of an atom? of Earth? How What do we express such numbers conveniently? • Place the following numbers in order of Place increasing value: 10 0.001 1 x 10 10 4 100000. 100000. Manipulate numbers • Multiply and divide 5 x 103 and 2 x 10-4 • (5 x 103) x (2 x 10-4) = 5 x 2 x 103 x 10-4 10 = 10 x 10-1 10 = 1 x 100 = 1 10 • (5 x 103) / (2 x 10-4) = 5/2 x 103/10-4 = 2.5 x 107 2.5 Derived Units: Density • Density: d = mass / Volume • units of g/mL or g/cm3 • What causes substances to What have different densities? • Density is a fundamental Density property of matter ! property Density • Carbon dioxide gas is more dense than Carbon helium gas. Why? helium Density • Water is more dense than ice. Why? ICE WATER Density • Why is the Why density of a solid usually greater than that of its liquid, which is greater than that of its gas? gas? gas liquid solid 1.5 Uncertainty in Measurement The difference between precision and accuracy: Significant Figures • What are significant figures? Why are they What important? When do you need to worry about them? them? Procedure for significant figures Procedure Count all non-zero digits. What about zeros? Count What Is there a zero to the left of Is the first nonzero digit? the No Yes Not significant Not significant Is there a zero between nonzero digits? Yes No If there is a zero at the end of the number, is it to the right of the decimal point? Yes Not significant No May or may not be Significant.
