Organic chemistry for Dummies - Download as a PDF or view online for free.Oxidation numbers are assigned to elements using these rules: Rule 1: The oxidation number of an element in its free (uncombined) state is zero — for example, Al (s) or Zn (s). This is also true for elements found in nature as diatomic (two-atom) elements. Rule 3: The sum of all oxidation numbers in a neutral compound is zero.Solubility = Constant x Pressure. The "constant" in Henry's law is Henry's constant, and its value depends on the gas, solvent, and temperature. A particularly useful form of Henry's law relates the solubility (S) and pressure (P) between two different states: According to this relationship, tripling the pressure triples the gas solubility.Chemistry Workbook For Dummies with Online Practice .

For example, knowing the differences between the density of quartz and diamond allows a jeweler to check out that engagement ring quickly and easily. Density ( d) is the ratio of the mass ( m) to volume ( v) of a substance.Now consider the dimensions of the cube in centimeters: Calculate the volume using these measurements, and you get. This volume is much greater than 2.54 cm 3! To convert units of area or volume using length measurements, square or cube everything in your conversion factor, not just the units, and everything works out just fine.Welcome to the Chemistry library!
