Chemical Quantities The MOLE CHAPTER 7 THE MOLE: A MEASUREMENT OF MATTER A mole (mol) is a unit of measurement Types of measurement include Counting/weighing/volume/ number of units Examples of other Quantitative measurement units Pair/Dozen/Ream Mole The term representative particles is a generic term that can refer to Atoms (single element), or Diatomic molecules (two of one type of element), or Formula units (what makes up an ionic compound) or Molecules (what makes up a molecular compound), or electrons or protons, or ions, etc Mole It is typically referred to as a mole of atoms or a mole of molecules A mole is also called Avogadro?s number For example: One mole would be 6.022 x 1023 representative particles Why use moles?

Notes - Double Replacement Products TERMS Soluble - substances that can be dissolved in water. Insoluble - substances that cannot be dissolved in water. Precipitate - a substance that falls out of solution when it is one of the products of a reaction. Precipitates are insoluble in water. The symbol for a precipitate is ? and would be a solid (s) for the state of matter RULES In a double replacement reaction the metal parts of each reactant switch places. Write down the new products. Look up the new products in a table of solubilities. If a product is listed as being insoluble, this product is a precipitate. Write the symbol for a precipitate, ? , after any product that is listed in the table of solubilities as being insoluble.

REACTANTS ?PRODUCTS 1.? Starting substances (reactants) becomes new substances (products). 2. Bonds are broken and new bonds are formed, but atoms are not created or destroyed (just rearranged). Law of Conservation of Mass PRODUCTS REACTANTS SENTENCE EQUATION Iron reacts with oxygen to produce rust WORD EQUATION Iron + oxygen ? iron (III) oxide SKELETON EQUATION Fe + O2 ?Fe2O3 These DO NOT indicate the relative amounts of the reactants and products. BALANCED EQUATION most correct equation includes the physical states of each substance uses coefficients 4Fe(s) + 3O2(g)?2 Fe2O3(s) Learn chart of symbols on page 206 in text.

Campbell's Biology, 9e (Reece et al.) Chapter 2 The Chemical Context of Life This chapter presents basic chemical principles for understanding the chemical context of living organisms, from atomic structure to the nature of chemical bonds and an introduction to chemical equilibrium. These questions focus on elements most important to life or the study of life, including the elements that comprise organic molecules and important trace elements. Some isotopes are important in geologic dating and in biological tracer studies. How elements participate in forming different types of chemical bonds is essential to mastering subsequent topics on the behavior and properties of biological molecules, structures, and energy metabolism.

Introductory Questions #1 Name the seven main properties of life. (Pg. 3) Which of the hierarchial levels of biology is the lowest in regard to carrying on and sustaining all life activities and is the fundamental unit of life? (pg 5) Introductory Questions #1 3. In your own words briefly describe what ?emergent properties? are. 4. How is negative feedback different from positive feedback? (pg. 11) What do these mechanisms do for a living thing? 5. Name the three domains of life. Which domain includes four out of the six kingdoms of life? 6. Why is natural selection considered the ?mechanism? for evolutionary adaptations to occur? 7. How is a hypothesis different from a theory?

Crystalline solid - solids with regular, repeating geometric arrangements of atoms, ions, or molecules Amorphous solids - noncrystalline solid with random arrangement of atoms or molecules ? **crystalline solids are more common and well-known ? Arrangements can be thought of as packing marbles together in a box (especially since atoms are spherical) We can reduce space between atoms--but not eliminate it--by rearranging the atoms in the structure "packing efficiency" - percentage of total volume that is actually occupied by atoms in a crystal lattice Affected by density of the material ? ? ? Types of Structures ? ? Cubic Crystal lattices: ? ? ?
