The algebraic sum of the oxidation number of various atoms = 1

Error converting from MathML to accessible text.

The algebraic sum of the oxidation number of various atoms = 2

therefore space space space space space space space plus 1 space plus straight x space plus 4 left parenthesis negative 2 right parenthesis space equals space minus 2 or space space space space space space space space space space space space space straight x space minus space 7 space equals space minus 2 or space space space space space space space space space space space space space space space straight x space equals space plus 5.
