Lecture 8/30 Dr. Ross Dalbey Finishing Ch. 2  Exothermic: chemical change that transfers energy to its surroundings  Endothermic: removes energy from its surroundings 2  Kinetic energy: energy that occurs during movement (K=.5mv )  Potential energy: energy that’s possessed by virtue of its position relative to another (Eg=mgh) o Energy stored in chemical bonds  Mass-energy equivalence o Law of Conservation of Mass & Energy: total quantity of mass & energy in the universe is fixed and does not change o Law of Conservation of Mass: the total mass of the reactants in a chemical change is equal to the total mass of the products  Phosphorus experiment by Antoine Lavoisier  Disproved the Phlogisten Theory o Law of Conservation of Energy: the energy lost or used in one form is always exactly equal to the energy gained in another form.  All energy gained (used) in the home is lost (generated) by the power plant. Chapter 3: Measurement & Chemical Calculations  Scientific Notation B o A x 10  A = coefficient  10 = exponential  B = exponent 5  E.g., 800,000 = 8 x 10  E.g., .000008 = 8 x 10 -6  E.g., .01 = 10-2 o Practice  Volume of gasoline used in the US each year  Standard Notation: 550,000,000,000 L 11  Scientific Notation: 5.5 x 10 L  Conversion Factors o Dimensional Analysis 61 12 years months 1 year  = 732 months 42.07 .6214 km mi 1 km Lecture 8/30 Dr. Ross Dalbey  = x miles o Equivalency: two quantities that are equivalent in value  12 in = 1 ft o Conversion factor: equivalency expressed as a fraction  12 in/1ft  Aren’t always exact  E.g., 30 mph  Any measure is inexact bc there is always error  Three lines (like an E) means exact  Solving a Quantitative Chemistry Problem o Steps  Analyze: What is given & what is needed?  Properties & units o E.g., distance & miles  Identify: What equivalencies & conversion factors are needed? o E.g., How many miles in a kilometer?  Construct: How will you set up the problem so that the units cancel?  Set up dimensional analysis  Check: Does the answer make sense? What did I learn?  Units o SI Units: subset of metric units  Mass = kilogram (kg)  Length = meter (m)  Time = seconds (s)  Temperature = Kelvin (K)  Amount of Substance = mole (mol) Lecture 8/30 Dr. Ross Dalbey o Prefixes can be placed in front of any unit to increase or decrease its size by factors of 10.  Metric volume: liter (L)  Smaller metric volume: milliliter (mL) o Mass: measure of the quantity of matter  Mass of an object is always constant o Weight: measure of the force of gravitational attraction  Weight on the moon is different than weight on earth o Length: measure of distance  Meter: the distance that light travels in a vacuum in 1/299792458 seconds o Derived Unit: combination of two or more SI base units
