Chemistry: January 25  ­February 5  h th  The energy and composition of matter changes throughout its different states (gas, liquid, solid)  Pure substances: compounds or elements  Law of Definite Proportions­ each substance is independent of location; compounds are  identical and the chemical composition ratio always stays the same   Compounds are distinguished by their properties:  o Chemical­the way they react  o Physical­ the way they appear Chemical Composition SI Base Units: Mass Kilogram­ kg Length Meter­ m Temperature Kelvin­ K Amount of Substance  Mole­ mol Time Second­ s Metric System: Tera­ 1012 9 Giga­ 106 Mega­ 10 Kilo­ 103 ­1 Deci­ 10­2 Centi­ 10 Mili­ 10­3 Micro­ 10­6 ­9 Nano­ 10 Pico­ 10­12 Femto­ 10­15 Additional Conversions: 1 inch 2.54 centimeters 1.00 quarts 946 milliliters 1.00 pound 454 grams Temperature  The randomness of motions generates a temperature in a BULK sample of matter  Higher temperature­ more motion and interactions between molecules  Convert temperature (degrees F or C):  o Add 40 to the initial temperature o Multiply by the conversation (9 degrees Celsius = 5 degrees Fahrenheit)  o Subtract the 40 degrees Density  Mass/Volume Making Measurements and Rounding  Accuracy­ how close one is to the correct value (hard to know if correct value is not  given)  Precision­ how closely each the found values agree  Significant Figures 1. All non­zero digits 2. Zeros that are between non­zero digits or are on the right­hand side of numbers  with a decimal   Ex. 2100 only has 2; however, to represent it with 4 sig figs, you must  write it like: “2100.” or in scientific notation (2.1 * 10 )  Order of Operations 1. Parenthesis  2. Powers/roots 3. Multiplication/division 4. Addition/subtraction o LEFT TO RIGHT!!!  Round Off Rules o For multiplication and division, the answer should have the least amount of given  significant figures o For subtraction and addition, the answer should have the least amount of given  decimal places o If last digit is greater than 5­ round up; less than 5­ keep as it is o Example: Dalton’s Atomic Theory    Two different compounds that contain the same elements only will carry the same ratio Example:  Compound CO CO 2 Ratio 1:x 1:(2)x  One can find the ratio between elements by calculations such as in this example.  ­Note: the mass of one elements must be found to equal zero (sulfur) to find the mass of  the other element (fluorine).  Periodic Tabl    Arranged by increasing average mass   Horizontal rows­ periods  Vertical rows­ families/groups Isotopes   Same element with a different number of neutrons, and therefore a different atomic mass  Can be found with a mass spectrometer  Average mass of each element is found through calculations using the mass of the various isotopes Ions  Ions are elements with a charge   Anions­ negative  Cations­ positive  Ions bond through electrostatic attraction (usually gain or lose electrons) o Metals lose electrons and become cations o Non­metals gain electrons and become anions  Compounds must form in a fixed ratio
