PPT-Oxidation & Reduction

Aka REDOX reactions Electrochemistry The study of chemical reactions involving the transfer of electrons between reactants Oxidation Loss of electrons happens at the anode Reduction gain of electrons. Part 1. Notes 11. Beginning Unit 4. Salt on icy roads can make driving safer, but the salt that clings to the metallic parts of cars can cause them to corrode or rust relatively quickly. . This corrosion is one example of a chemical reaction called oxidation-reduction. You will learn about oxidation-reduction reactions.. p.232-234. Assigning Oxidation Numbers. Oxidation Number. : positive or negative number assigned to an atom according to a set of . rules. Rules for Assigning Oxidation Numbers. The oxidation number of . Chemical Equations. This equation means:. 4 Al(. s. ) + 3 O. 2. (. g. ) 2 Al. 2. O. 3. (. s. ). 4 Al atoms + 3 O. 2. molecules yield 2 molecules of Al. 2. O. 3. 4 Al . moles. Definition. If oxidation occurs, then reduction must also occur. Any chemical process in which elements undergo a change in oxidation number is a . Redox reaction. Example. 2Na + Cl. 2. . → 2Na. Reduction.

What is this NCEA Achievement Standard?. When a student achieves a standard, they gain a number of credits. Students must achieve a certain number of credits to gain an NCEA . certificate (80 for Level 3). A large amount of energy is obtained when fatty acids undergo. oxidation in the mitochondria to acetyl CoA.. beta oxidation, (. β . oxidation). . which removes two-carbon segments containing the alpha and beta carbon from the carboxyl end of the fatty acid..

Cells use chemical energy stored in organic molecules to regenerate ATP, which powers work.. Living cells require energy from outside sources.. 1.2.3: Redox explains the chemistry behind batteries and electroplating precious metals onto strong base metals. It also explains how to break apart water into hydrogen and oxygen, and lots more.. 4: These 2 reactions are always paired and balanced.. pair of molecules of which one is reduced and the other is oxidized (e.g., lactate-pyruvate, . NADH-NAD. +. , and FADH. 2. -FAD. each pair constitutes a half reaction . . the reductant of one pair donates electrons and the oxidant of the other pair accepts the electrons.
