CHAPTER 1-3 Review Jesperson, Brady, Hyslop. Chemistry: The
Molecular Nature of Matter, 6E 2 Learning Objectives Scientific
Method Matter: definition, elements, compounds, mixtures,
changes/properties Atomic Theory Law of definite proportions Law of
conservation of mass Chemical formulas Chemical equations Balancing
Measurements: units, conversions, uncertainty Significant Figures
Density Subatomic particles Atomic #, mass #, atomic weights
Periodic Table Ionic Compounds, hydrates, molecular compounds Basic
nomenclature
Slide 3
Chapter 1 Scientific Method Jesperson, Brady, Hyslop.
Chemistry: The Molecular Nature of Matter, 6E 3 1.Make
observations/collect data Empirical fact Something we see, hear,
taste, feel, or smell Something we can measure Organize data so we
can see relationships 2.Law or Scientific Law Usually an equation
Based on results of many experiments Only states what happens Does
not explain why they happen 3.Hypothesis Mental picture that
explains observed laws Tentative explanation of data Make
predictions Leads to further tests Go to laboratory and perform
experiments 4.Theory Tested explanation of how nature behaves
Devise further tests Depending on results, may have to modify
theory Can never prove theory is absolutely correct

Chapter 1 Elements Jesperson, Brady, Hyslop. Chemistry: The
Molecular Nature of Matter, 6E 4 Substances that cant be decomposed
into simpler materials by chemical reactions Substances composed of
only one type of atom Simplest forms of matter that we can work
with directly More complex substances composed of elements in
various combinations diamond = carbongold sulfur
