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.

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 ...In this case, the best solution is to drain your hot tub, scrub it, and start over with fresh water.
