Chemistry 1210: Introduction to General Chemistry Dr. Gina M. Florio 18 October 2012 Brady, Jespersen, Hyslop Chapter 7 Energy & Chemical Change Thermochemistry: the study of energy flow during a chemical reaction Ch. 7.1 Energy: the ability to do work; often measured as heat Kinetic Energy: the energy of motion; KE = ?mv2 Potential Energy: stored or positional energy; chemical energy (no simple eqn.) Conservation of Energy: 1. Energy cannot be created or destroyed 2. Energy is only converted from one form to another (KE ? PE) 3. Total energy of the universe (or an isolated system) is constant Thermochemistry: Basic Definitions Units of Energy 1 Joule (J) ? the KE possessed by a 2 kg object moving at a velocity of 1 m/s 1 cal = 4.184 J (exactly) 1 kcal = 4.184 kJ

Chemistry 1210: Introduction to General Chemistry Dr. Gina M. Florio 11 October 2012 Jespersen, Brady and Hyslop Chapter 6 Oxidation-Reduction Reactions Reactions that involve the transfer of electrons are called oxidation-reduction or redox reactions. Oxidation is the loss of electrons by a reactant. Reduction is the gain of electrons by a reactant LEO the lion goes GER! LEO: Losing Electrons during Oxidation GER: Gaining Electrons during Reduction Redox Reactions Redox Reactions In a balanced redox reaction, the total number of electrons lost by one substance is the same as the total number of electrons gained by the other. Oxidizing agent ? the substance that accepts the electrons. Reducing agent ? the substance that gives up the electrons.

Chemistry 1210: Introduction to General Chemistry Dr. Gina M. Florio 27 Sept. 2012 Jespersen, Brady, Hyslop Chapter 5B Molecular View of Reactions in Aqueous Solution Properties of Solutions: Quantitative Composition The molar concentration or molarity (M) is defined as: units of M = mol/L (mol L-1) Example: How many grams of AgNO3 are needed to prepare 250 mL of a 0.0125 M AgNO3 solution? NOTE: You can also solve this for concentration OR liters of solution CH. 5 Properties of Solutions: Quantitative Composition Solutions of high concentration can be diluted to make solutions of lower concentration. Dilution: CH. 5 Example: How much 1.0 M CuSO4 (aq) solution is required to prepare 250 mL of a 0.10 M CuSO4 (aq) solution? How much water is required? Solution Stoichiometry CH. 5

Kinetic Theory Of Gases Postulates of the Kinetic Theory of Gases: A gas consists of a large number of tiny particles that are in constant, random motion The gas particles occupy a net volume so small in relation to the volume of their container that their contribution to the total volume can be ignored The collisions between particles and the walls of the container are perfectly elastic (no energy transfer) Kinetic Theory of Gases relates temperature to average kinetic energy Kinetic Theory of Gases (aka Kinetic Molecular Theory) can be used to explain the Gas Laws: Pressure-Volume Relationship (Boyle?s Law) P? 1/V or V ? 1/P (at constant n, T) Pressure-Temperature Relationship (Guy-Lussac?s Law) ?T, ?v ?v, ?P Volume-Temperature Relationship (Charles?s Law)

Livingston 1 Luke Livingston Mrs. Bassett Human Geography 6 October 2014 Population Growth in Graph The graph appears to be going at a stable incline and does not change throughout any part in the line graph The only reason the graph looks as though it is going at a steady rate when in fact the pace of increases in population is in fact much more dramatic. The increase for each year shown on the table increases between 400 and 800. But the interval for each year in the beginning is 50 from 1800-1900 then it goes to 30, then to 20 and for the rest of the shown years it goes by 10. This means that it required far more years in the past to add up the same interval than the rate of increase towards the present and future.
