Campbell's Biology, 9e (Reece et al.) Chapter 3 Water and Life Life evolved in the ocean, and the chemistry of life occurs in an aqueous environment. These questions explore the properties of water that are important to sustain life?s chemical processes, organismal physiology, and interactions of organisms with their environment. Quantitative properties such as heat content, molarity, and pH are also addressed. A few questions address how human activities affect the global environment through acid rain and acidification of the ocean. Multiple-Choice Questions 1) In a single molecule of water, two hydrogen atoms are bonded to a single oxygen atom by A) hydrogen bonds. B) nonpolar covalent bonds. C) polar covalent bonds. D) ionic bonds. E) van der Waals interactions.

Chemistry 1210: Introduction to General Chemistry Dr. Gina M. Florio 20 Sept. 2012 Jespersen, Brady, Hyslop Chapter 5A Molecular View of Reactions in Aqueous Solution A solution is a homogeneous mixture in which the two or more components mix freely. The solvent is taken as the component present in the largest amount. A solute is any substance dissolved in the solvent. Definitions CH. 5.1 Example of a Solution Formation of a solution of iodine molecules in ethyl alcohol where ethyl alcohol is the solvent and iodine the solute: CH. 5.1 Crystal of I2 placed in ethanol: A solution of I2 in ethanol: Properties of Solutions: Qualitative Composition The relative amounts of solute and solvent are often given without specifying the actual quantities.

Name Period Chapter 3: Water and Life Concept 3.1 Polar covalent bonds in water result in hydrogen bonding Study the water molecules at the right. On the central molecule, label oxygen (O) and hydrogen (H). What is a polar molecule? Why is water considered polar? Now, add + and - signs to indicate the charged regions of each molecule. Then, indicate the hydrogen bonds. Explain hydrogen bonding. How many hydrogen bonds can a single water molecule form? Concept 3.2 Four emergent properties of water contribute to Earth?s suitability for life Hydrogen bonding accounts for the unique properties of water. Let?s look at several. Cohesion, Adhesion, and Surface Tension Distinguish between cohesion and adhesion.
