Laboratory Requirements Students need to purchase the following items from around the university before they come to the labs (starting September 26th): 1.- Laboratory manual (Document Services) $10.00-$15.00 2.- Breakage card (Cashiers Office) $25.00 3.- Safety glasses (Bookstore) $ 5.00 Lab Coats Required, $30.00 Essex Hall Lab D 12:00-3:00pm MWF See Jenny or Sharonna General Chemistry: Chapter 1

  3. General Chemistry Principles and Modern Applications Petrucci • Harwood • Herring 8th Edition Chapter 1: Matter—Its Properties and Measurement General Chemistry: Chapter 1

  4. Contents • Physical properties and states of matter • Système International Units • Uncertainty and significant figures • Dimensional analysis http://cwx.prenhall.com/petrucci/chapter1/deluxe.html General Chemistry: Chapter 1

  5. Properties of Matter Matter: Occupies space, has mass and inertia Composition: Parts or componentsex. H2O, 11.19% H and 88.81% O by mass Properties: Distinguishing features physical and chemical properties General Chemistry: Chapter 1

  6. States of Matter Examples of physical changes. The chemical composition remains constant. General Chemistry: Chapter 1

  7. Classification of Matter NO YES Physical Separation ? Chemical Separation ? Uniform Throughout ? NO YES YES NO General Chemistry: Chapter 1

  8. Separations Filtration Distillation Paper Chromatography General Chemistry: Chapter 1

  9. Separating Mixtures Chromatography mixture As the mixture moves through the stationary phase, the components are separated based on their retention time. General Chemistry: Chapter 1

  10. Adding and subtracting. Use the number of decimal places in the number with the fewestdecimal places. 1.14 0.6 11.676 13.416  Significant Figures Count from left from first non-zero digit. Significant Figures 3 Number 6.29 g 0.00348 g 9.0 1.0  10-8 100 eggs 100 g  = 3.14159 3 2 2 Infinite (exact) 13.4 bad notation various General Chemistry: Chapter 1

  11. Rounding Off 3rd digit is increased if 4th digit  5 Report to 3 significant figures. 10.235  12.4590  19.75  15.651  . 10.2 12.5 19.8 15.7 Significant figures Multiplying and dividing. Use the fewest significant figures. 0.01208  0.236 = 0.512 = 5.12  10-3 General Chemistry: Chapter 1

  12. Units S.I. Units Length metre, m Mass Kilogram, kg Time second, s Temperature Kelvin, K Quantity Mole, 6.022×1023 mol-1 Derived Quantities (based on SI units) Force Newton, kg m s-2 Pressure Pascal, kg m-1 s-2 Energy Joule, kg m2 s-2 Other Common Units Length Angstrom, Å, 10-8 cm Volume Litre, L, 10-3 m3 Energy Calorie, cal, 4.184 J Pressure 1 Atm = 1.064 x 102 kPa 1 Atm = 760 mm Hg General Chemistry: Chapter 1

  13. SI Prefixes General Chemistry: Chapter 1

  14. Temperature T(K) = t(°C) + 273.15 t(°C) = 5/9 [t(°F) – 32] General Chemistry: Chapter 1

  15. Relative Temperatures Boiling Point of Water Hot Day Melting Point of Ice Very Cold Day Boiling Point of Liquid Nitrogen Absolute Zero General Chemistry: Chapter 1

  16. Volume General Chemistry: Chapter 1

  17. Density • = m/V m = Vd V = m/d g/mL Mass and volume are extensive properties Density is an intensiveproperty Independent on the quantity of matter present Dependent on the quantity of matter present General Chemistry: Chapter 1

  18. Conversion What is the mass of a cube of osmium that is 1.25 inches on each side? Have volume, need density = 22.48g/cm3 Does the answer make sense ?? General Chemistry: Chapter 1

  19. The Gimli Glider, Q86, p30 Wrong units General Chemistry: Chapter 1

  20. Uncertainties • Systematic errors. • Thermometer constantly 2°C too low. • Random errors • Limitation in reading a scale. • Precision • Reproducibility of a measurement. • Accuracy • How close to the real value. General Chemistry: Chapter 1

  21. End of Chapter Questions 1, 3, 5, 12, 14, 17,18, 20, 30, 35, 41, 49, 50, 61, 72, 74, 79. General Chemistry: Chapter 1
