Answer to: What is the oxidation half reaction for the following equation: Cr_2O_7^{-2} +Fe^{+2} \rightarrow Cr^{+3} + Fe^{+3} By signing up,...
A non-spontaneous redox reaction occurs because the overall cell potential when the oxidation and reduction half-reactions are coupled is negative. This can still proceed to spontaneity through the supply of energy through current. This process is called electrolysis. ...
Step 1: Understanding Half ReactionsA half reaction is a representation of either the oxidation or reduction part of a redox (reduction-oxidation) reaction. In a redox reaction, one species is oxidized (loses electrons) while another is reduced (gains electrons). ...
A redox reaction, also referred to as an oxidation-reduction reaction, involves the loss or gain of electrons. The electrons are transferred between two species and their oxidation number changes as a result. Species that can undergo redox reactions incl
What is the oxidizing agent in the reaction {eq}Fe_2O_3(s)+2Al(s) \rightarrow 2Fe(s)+Al_2O_3(s) {/eq}? Assigning Oxidation Numbers: There is a series of rules that is used to help assign oxidation number to chemicals that most students will m...
In a particular redox reaction, {eq}MnO_2 {/eq} is oxidized to {eq}MnO_4 {/eq}. What is the reaction mechanism for this?Redox Reaction:In chemistry, redox reactions are marked by the process of oxidation as well as the process of reduction that takes place si...
The half reaction with the most positive standard reduction potential will undergo reduction, the other half reaction will go in the reverse direction (oxidation). Even though both standard reduction potentials are negative, -0.14 V is more positive than -0.76 V. The reaction that occurs in this...

Acrylamide is formed in food primarily through the Maillard reaction between reducing sugars and asparagine (Mottram et al., 2002), and the formation in food depends on the composition of the food, the cooking methods, the temperature (clear increase >120 °C) and the duration of cooking, ...
Once the electron was discovered and chemical reactions could be explained, scientists realized oxidation and reduction occur together, with one species losing electrons (oxidized) and another gaining electrons (reduced). A type of chemical reaction in which oxidation and reduction occurs is called a ...
