PPT-Redox Class #1: oxidation reduction reactions made fun

123 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. 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. . 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. Redox. ) Reactions. Chapter 20. 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.. REDOX PROCESSES. 9.1. OXIDATION AND REDUCTION. ESSENTIAL IDEA. Redox (reduction-oxidation) reactions play a key role in many chemical and biochemical processes.. NATURE OF SCIENCE (1.9). How evidence is used – changes in the definition of oxidation and reduction from one involving specific elements (oxygen and hydrogen), to one involving electron transfer, to one invoking oxidation numbers is a good example of the way that scientists broaden similarities to general principles.. Oxidation and reduction. Oxidation and reduction – oxygen . transer. A substance has been . oxidised. if it . gains oxygen. . Oxidation is gain of oxygen.. A substance has been . reduced. if it . REDOX REACTIONS . OILRIG – . O. xidation . I. s . L. oss of electrons. . R. eduction . I. s . g. ain of electrons. This is really important. Think of January sales!. OXIDATION NUMBER RULES. Oxidation numbers which are assigned to ions (of each element) in a compound help us to write half equations and full ionic equations.. 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).
