Lecture 8/23 Dr. Ross Dalbey Chemistry 1101 Introduction to Chemistry I. Aurora borealis, a.k.a. Northern Lights A. Green: atomic oxygen B. Magenta (low altitude): molecular oxygen II. Antoine Lavoisier (1743-1794) A. Experimented with burning phosphorus 1. P + 5O  2P O 4 2 2 5 B. Disagreed with the Phlogisten Theory 1. Combustible materials have a fire-like element that is released upon heating C. Mercury burning experiment 1. Lavoisier burned liquid mercury a) 2Hg + O  2HgO 2. Theorized that mass of reactants > mass of products, but was disproven III. Scientific Method A. Observe B. Think critically, ask questions C. Propose a hypothesis 1. Hypothesis: a statement proposed to explain a series of observations and their relationships a) Must be stated in such a way that can be tested b) Cannot be proven, only disproven i) Supported or refuted D. Assume hypothesis is true and make a prediction E. Test prediction via experimentation 1. Experiment: tests that determine a hypothesis’s validity a) Often performed by various scientists or investigators F. Revise or change hypothesis if necessary 1. This only happens if hypothesis isn’t supported by experiment G. Repeat experiments/hypothesis revision as necessary H. Hypothesis becomes theory through several various experiments 1. Theory: the formulation of a robust and apparent relationship among observed phenomena verified by multiple experiments a) Modified if additional experiments don’t support it 2. Hypothesis and theory are similar, the difference being that while both can be tested, only a theory can be proven Lecture 8/23 Dr. Ross Dalbey Chemistry 1101 IV. Theory vs. Law A. Law: an explicit statement of fact 1. Ex. Law of Conservation of Mass  mass of reactants = mass of products
