Oxidation numbers are used to keep track of electrons in atoms. There are rules for assigning oxidation numbers to atoms. Oxidation is an increase in oxidation number (loss of electrons); reduction is a decrease in oxidation number (gain of electrons).

In its pure elemental form, oxygen is highly reactive, and it readily makes compounds with most other elements. It is also the most abundant element by mass in the Earth's crust. The class of reactions called oxidation and reduction were originally defined with respect to the element oxygen.

Hydrogenation is simply the net addition of a hydrogen (H2) molecule to a compound, in the form of a hydride ion (H- , a proton plus a pair of electrons) and a proton.

You should find that copper has been reduced from +2 to +1; oxygen (in the gas) has been reduced from 0 to -2 (oxygen in the SiO 2 is unchanged); and three of the four sulfurs on the left-hand side have been oxidized from -2 to +4 (the other is unchanged).

What is the value of E for this reaction when the pH of the solution is maintained at 7.00? What is the value of E for this reaction when the pH of the solution is maintained at 10.00? Use the following cell between Cu/Zn and the electrode potentials for the half cells to answer the question:

Two cyclic stereoisomers can form from each straight-chain monosaccharide; these are known as anomers. In an aqueous solution, an equilibrium mixture forms between the two anomers and the straight-chain structure of a monosaccharide in a process known as mutarotation.
