Chapter 10: Photosynthesis ?Photosynthesis is the process that converts solar energy into chemical energy ?Directly or indirectly, photosynthesis nourishes almost the entire living world This chapter is as challenging as the one you just finished on cellular respiration. However, conceptually, it is a little easier because the concepts learned in Chapter 9: Chemiosmosis, and an electron transport system play a central role in photosynthesis. 1. As a review, define the terms autotroph and heterotroph. Keep in mind that plants have mitochondria and chloroplasts and do both cellular respiration and photosynthesis.

Chemistry 1210: Introduction to General Chemistry Dr. Gina M. Florio 26 Nov. 2012 Jespersen, Hyslop, & Brady Chapter 10 Chemical Bonding & Molecular Structure VSEPR Theory Valence Shell Electron Pair Repulsion (VSEPR) Model: 1. e- pairs repel each other 2. e- pairs position themselves in 3D to minimize repulsion Molecules have well defined shapes based on their electronic structure. Molecular Structure: Shapes of molecules The shapes of molecules are derived from 5 different geometric structures that are classified by number of electron domains contained around the central atom. Two types of electron domains: Bonding domains (e- pairs in bonds) Nonbonding domains (e- pairs associated with a single atom)

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

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)

Properties of Gases Recall that our understanding of kinetic energy in molecular systems relies on a molecular-level picture of gases. Kinetic Theory of Gases (CH 7) Example: Pressure Units of Pressure Standard atmosphere (atm): the pressure needed to support a column of mercury 760 mm high measures at 0 ?C The SI unit of pressure is the pascal (Pa): Pressure Measurements Open-ended Mercury Manometer:

More than 40% of China's arable land degraded: report (Agencies/chinadaily.com.cn)Updated: 2014-11-05 11:56 CommentsPrintMailLargeMediumSmall ? Villagers sow peanut seeds in Zaozhuang, East China's Shandong province on April 17, 2014. [Photo/IC]? More than 40% of China's arable land is suffering from degradation, seriously reducing the country's capacity to produce food for the world's biggest population, Xinhua reported Tuesday. The rich black soil in Northeastern Heilongjiang province, which forms part of China's bread basket, is thinning, while farmland in China's south is suffering from acidification, the report said, citing agriculture ministry statistics.

Global Survey Says We're Eating Better, But Our Diet Is Still?Unsustainable More people are eating local and organic foods, but that's not nearly enough. Jason Plotkin, owner of a small organic farm near Golden, Colorado, grapples with red, white, and golden beets he plans to sell at a farmers market. PHOTOGRAPH BY CYRUS MCCRIMMON, DENVER POST/GETTY Andrea Stone for?National Geographic PUBLISHED SEPTEMBER 29, 2014 More people are eating local and organic foods and plan to consume less meat and bottled water. However, most also believe they lack enough information and influence to become more environmentally sustainable consumers, a new National Geographic survey has found. Share Share on emailEmail More ?
