PPT-Oxidation Numbers (Ox #’s)

What are they used for Why do you need to learn them to write chemical names and chemical formulas to balance redox equations for analytical organic and inorganic chemistry What is an oxidation number. 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 . IGCSE Chemistry . 620. OXYGEN. Gaining of oxygen is called oxidation.. Carbon + Oxygen .  Carbon dioxide. Carbon is oxidised to carbon dioxide.. Methane burns in oxygen.. CH. 4. . + . 2O. 2. . It’s everywhere man!. Q: What does it involve?. A: The combination of an element/molecule. with Oxygen in the air or water…. Q: What is the balanced chemical equation?. __Fe. 3. C. +. __O. Chapter 4.
