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 UNIT 8 SOLUTIONS 02-24-13 Solubility: A measure of how well a solute can dissolve in a solvent at a given temperature and pressure. Solutions are homogeneous mixtures Solute: The substance dissolved into another substance Solvent: The substance that does the dissolving Example: In a solution of salt and water, the salt is the solute and the water is the solvent NaCl (aq) recall that aq is the abbreviation for aqueous which means water is the solvent The more solute you add to a solution the more concentrated The less solute you add to a solution the more dilute Types of Solutions Saturated Solution: Contains the maximum amount of solute that can dissolve at a given temperature
Unit 4 Study List: Aqueous Solutions
Subject:
AP Chemistry Unit Four: Aqueous Solutions S T U D Y L I S T Properties of Aqueous Solutions ?? Define solute, solvent, and solution. Give examples. ?? Define electrolytes. Give operational and theoretical definitions of electrolytes. ?? Know that soluble ionic compounds and strong acids are strong electrolytes. Ionic compounds of low solubility [e.g. Mg(OH) 2 ] and weak acids/bases are weak electrolytes. ?? Know that molecular compounds (except acids) are non-electrolytes. ?? Know that alcohols (e.g. CH 3 OH )are not ionic hydroxides. Bases are usually metallic hydroxides. ?? Know the solubility rules. State whether an ionic compound is soluble in water. Precipitation Reactions ?? Know that ppt reactions are double

Final Review Sheet Radio Active Decays Alpha decay occurs when the nucleus emits an alpha particle. Alpha particles have a positive charge and are equivalent in size to a helium nucleus, and so they are symbolized as . Alpha particles are the largest radioactive particle emitted. This type of radioactivity results in a decrease in the atomic number by 2 and a decrease in the atomic mass by 4. The equation below shows uranium-234 undergoing alpha decay:
