This chapter discusses the properties and measurement of matter, focusing on concepts such as the classification of substances, physical and chemical processes, and unit conversions in chemistry. • be able to distinguish between solids, liquids, and gases at all 3 levels of representation: symbolic (h2o), particulate (one molecule of h2o), and macroscopic (1 g of h2 o) o be able to recognize graphical representations of molecules o the properties of matter are related to its molecular level structure • understand that chemistry is an experimental science and depends on accurate, precise, and reproducible measurements o scientific method: an approach to acquiring knowledge based on observation of phenomena, development of a testable hypothesis, and additional experiments that test the validity of the hypothesis. o hypothesis: a tentative and testable explanation for an observation or a series of observations o scientific theory: a general explanation of widely observed phenomena that has been extensively tested. o scientific law: a concise and generally applicable statement of a fundamental scientific principle • matter can be divided into two principle classes (figure 1.2 in textbook): o pure substances: matter that cannot be separated into simpler matter by a physical process element: a pure substance that cannot be separated into simpler substances by an chemical process • atom: the smallest particle of an element that retains the chemical characteristics of the element compound: a pure substance that is composed of 2 or more elements linked together in fixed proportions and that can be broken down into those elements by some chemical process.

Simply put, it is the conversion between an amount in one unit to the corresponding amount in a desired unit using various conversion factors. this is valuable because certain measurements are more accurate or easier to find than others. College chemistry exam covering unit conversions, empirical formulas, molar mass, balancing equations, stoichiometry, iupac naming, and molecular formulas. Here are 25 questions, some from each unit that we covered in class. the questions on the final will look just like these questions (but they won't be these exact questions!). if you can answer these questions correctly in 30 minutes, then you are well prepared for the final. The underlying principal is unit conversion by which one type of unit is changed by another by use if conversion factor (relationship) 2. the conversion factor has the form of a ratio that allows for cancellation of one unit and its replacement of a new unit.
