Chemical polarity

Water is Special Polarity There are two types of covalent bonds, polar and nonpolar While nonpolar molecules share electrons equally, polar molecules do not. This results in one part of the molecule being partially positive and another part being partially negative. 2 Student Misconceptions and Concerns

Matter Classified by? Physical State (Gas/ Liquid/ Solid) Composition (Element/ Compound/ Mixture) States of Matter Gas (vapor) No fixed volume or shape Uniformly fills its container Can be compressed to occupy a smaller volume Can be expanded to occupy a larger volume Molecules are far apart, move quickly, and often collide with the surrounding container Liquid Distinct volume (independent of container) No fixed shape (assumes shape of occupied container) Can't be compressed Molecules are packed closely but can still move (they flow over each other, reducing viscosity Solid Definite shape and definite volume Can't be compressed Molecules have fixed positions an wiggle only slightly *Temperature and pressure changes lead to phase changes of the substance

Properties can be? Physical - can be observed without changing identity or composition of the substance Ex. Color, odor, Density, Melting Point, Boiling Point, Hardness Chemical - describe the way a substance may change or react to form other substances Ex. Flammability - the ability of a substance to burn in the presence of oxygen Intensive - do not depend on the amount of sample being examined Help to identify substances Ex. Temperature, melting point Extensive - Depend on the amount of sample Help to show quantity of a substance Ex. Mass, volume Physical and Chemical Changes Physical Change - substance changes its physical appearance, but not its composition Changes of state are physical changes Chemical Change - substance changes into a chemically different substance

3.2 Energy and Ecosystems I will wait until everyone is in their seats and has only a piece of paper and a pen/pencil and your homework on your desk. Again, the expectation is that there is no talking during the quiz. Talking will result in your quiz not being collected. Daily Quiz Name the ecosystem you created for homework List all 10 biotic and 5 abiotic factors Which biotic and abiotic factor did you remove? What are the consequences of it being removed? When you finish your quiz, please collect your assignments by the door. Daily Quiz Question Content Objective Students will? Follow the path energy takes in an ecosystem. Distinguish between producer, consumer, and decomposer. Model a trophic pyramid Demonstrate the first and second law of thermodynamics.

Chapter 12 ?2010, Prentice Hall Organic Chemistry, 7th Edition L. G. Wade, Jr. Infrared Spectroscopy and Mass Spectrometry Chapter 12 * Introduction Spectroscopy is a technique used to determine the structure of a compound. Most techniques are nondestructive (it destroys little or no sample). Absorption spectroscopy measures the amount of light absorbed by the sample as a function of wavelength. Chapter 12 Chapter 12 * Types of Spectroscopy Infrared (IR) spectroscopy measures the bond vibration frequencies in a molecule and is used to determine the functional group. Mass spectrometry (MS) fragments the molecule and measures their mass. MS can give the molecular weight of the compound and functional groups.
