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.

The pKa is derived from the equilibrium constant for the acid’s dissociation reaction, Ka, and uses a logarithmic scale to allow the pKa values to span wide ranges. pKa = –log Ka. The lower the pKa value of an acid, the stronger the acid. The higher the pKa value, the weaker the acid. Very strong acids have pKa values of less than zero ...The compounds that have ionic bonds are commonly called salts. In sodium chloride, a crystal is formed in which each sodium cation is surrounded by six different chloride anions, and each chloride anion is surrounded by six different sodium cations. The crystal structure is shown in the following figure. Notice the regular, repeating structure.

In organic chemistry, functional groups (or reactive centers) are small structural units within molecules that dictate how most of the compound's chemical reactions occur. Know these common functional groups you will run into in organic chemistry:

If the enthalpy change listed for a reaction is negative, then that reaction releases heat as it proceeds — the reaction is exothermic ( exo- = out). If the enthalpy change listed for the reaction is positive, then that reaction absorbs heat as it proceeds — the reaction is endothermic ( endo- = in). In other words, exothermic reactions ...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.Density is one of the most useful intensive properties of a substance, enabling chemists to more easily identify substances. 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.This table lists the locations and intensities of absorptions produced by typical functional groups. The IR spectrum of hexane (C 6 H 14) is shown in the next figure. Because hexane has only C-H and C-C bonds (and no functional groups), this spectrum can help orient you to the important regions in an IR spectrum. The IR spectrum of hexane.Mar 26, 2016 · Density is one of the most useful intensive properties of a substance, enabling chemists to more easily identify substances.
