 Mega (M) 10^6 kilo (k) 10^3 hecto (h) 10^2 deka (da) 10^1 deci (d) 10^-1 centi (c) 10^-2 milli (m) 10^-3 mirco (u) 10^-6 nano (n) 10^-9 Angstrom (Å) 10^-10 m K = C + 273.15 F = (1.8 x C) + 32 C = (F - 32) ÷ 1.8 Water = 1.000 g/mL Glycerin = 1.26 g/mL Magnesium = 1.74 g/mL Aluminum = 2.70 g/mL Lead = 11.34 g/mL Mass Density = --------- Volume Density = g/mL or g/cm^3 1 meter = 1.0936 yards 1 centimeter = .3937 inch 1 inch = 2.54 centimeters 1 kilometer = .62137 mile 1 mile = 5280 feet or 1.609 kilometers 1 kilogram = 2.20 pounds 1 pound = 453.59 grams 1 ounce = 28.3 grams 1 atomic mass unit = 1.6606 x 10^-27 1 liter = 10^-3 m^3, 1.0567 quarts 1 gallon = 3.785 liters 1 joule = 1 kg m^2/s^2 1 calorie = 4.184 joules avogadro's number = 6.022 x 10^23 Is it Physical or Chemical Change: Lighting a candle Chemical Stirring cake batter Physical Dissolving sugar in water Physical Decomposition of limestone by heat Chemical A leaf turning yellow Chemical Formation of bubles in a pot of water long before the water boils Physical Identify the reactants and products for the electrolysis of water Reactants = H20 Products = H2 and O2 atomic number= number of protons in the nucleus Electrons = number of protons in the nucleus The average atomic mass can be calculated by multiplying the atomic mass of each isotope by the fraction of each isotope present and adding the results. Ex. (62.9298)(0.6909) = 43.48 amu (64.9278)(0.3091) = 20.07 amu ------- 63.55 amu Law of definite composition= A compound always contains two or more elements combined in a definite proportion by mass Law of multiple proportions= Atoms of two or more elements may combine in different ratios to produce more than one compound Aluminum Al Antimony Sb Argon Ar Arsenic As Barium Ba Bismuth Bi Boron B Bromine Br Cadmium Cd Calcium Ca Carbon C Chlorine Cl Chromium Cr Cobalt Co Copper Cu Fluorine F Gold Au Helium He Hydrogen H Iodine I Iron Fe Lead Pb Lithium Li Magnesium Mg Manganese Mn Mercury Hg Neon Ne Nickel Ni Nitrogen N Oxygen O Palladium Pd Phosphorus P Platinum Pt Plutonium Pu Potassium K Radium Ra Silicon Si Silver Ag Sodium Na Strontium Sr Sulfur S Tin Sn Titanium Ti Tungsten W Uranium U Xenon Xe Zinc Zn Antimony = Sb = Stibium Copper = Cu = Cuprum Gold = Au = Aurum Iron = Fe = Ferrum Lead = Pb = Plumbum Mercury = Hg = Hydrargyrum Potassium = K = Kalium Silver = Ag = Argentum Sodium = Na = Natrium Tin = Sn = Stannum Tungsten = W = Wolfram Hydrogen Oxygen Nitrogen Chlorine Fluorine Bromine Iodine Polyatomic Molecules = 2 Polyatomic Molecules Sulfur = 8 = S8 Phosphorus = 4 = P 4 Cations are named the same as their parent atoms, as shown: K potassium = K⁺ potassium ion Mg magnesium = Mg2⁺ magnesium ion Al aluminum = Al3⁺ Aluminum ion To name an anion consisting of one element, us the stem of the parent element name and change the ending to -ide: F flourine = F⁻ fluoride ion Br bromine = Br⁻ bromide ion etc. Transition metals Cr 2⁺ or Cr 3⁺ Fe 2⁺ or Fe 3⁺ Cu ⁺ or Cu 2⁺ Ag ⁺ Cd 2⁺ Zn 2⁺ In classic nomenclature, when the metallix ion has only two cation types, the name of the metal (usually the Latin name) is modified with the suffixes -ous and -ic to distinguish between the two. The lower charge cation is given the -ous ending, and the higher one, the -ic ending Binary compounds containing two nonmetals you give the first element a prefix- such as mono- or deca- and the second element ends in -ide
