Ambiguity . is a word, phrase, or statement which contains more than one meaning.. Ambiguous words or statements lead to vagueness and confusion, and shape the basis for instances of unintentional humor. Ambiguity. (1) a statement which has two or more possible meanings.. (2) a statement whose meaning is unclear..     . Depending on the circumstances, ambiguity can be negative, leading to confusion or even disaster (the ambiguous wording of a general's note led to the deadly charge of the Light Brigade in the Crimean War). .

The presence of two or more possible meanings in a single passage. . the possibility of interpreting an expression in two or more distinct . Oxidation and Reduction. Oxidation-reduction (. redox. ) reactions involve transfer of electrons. Oxidation – loss of electrons. Reduction – gain of electrons. Both half-reactions must happen at the same time. The oxidation state is a “measure of the degree of oxidation of an atom in a substance” and it is the fundamental key to understanding redox reactions, reaction mechanisms, catalysis, etc. I Write the Molecular, Total Ionic, and Net Ionic Reactions for the chemical reactions below: .
