Chapter 10 __________reactions are reactions where electrons transfer from one atom or ion to another. reactions are reactions where oxygen is a reactant and carbon dioxide and water are products. 10.1 is the gain of electrons and is the loss of electrons. T or F: Reduction and oxidation happen simultaneously. is the apparent charge on an atom when lone pairs or bonding electrons are assigned to it. Oxidation numbers in an ionic compound is determined by the number of given away or added to form a stable octet. Covalent compound: • Oxidation number for elements by themselves is ____ • Oxidation number for monatomic ions is the ________ • Oxidation number for Hydrogen in front of a compound is ______ and at the end of a compound is __ • Alkali metals have an oxidation number of ___ and Alkaline Earth metals are ___ • Oxidation number for Oxygen is ____ unless it's in peroxide. • The sum of oxidation numbers in a compound have to equal __ • In a polyatomic ion, the oxidation number equals the _____ If the element's oxidation number is reduced, it's _______ If it increases, it's _______ The reducing agent is the compound containing the _______ element. The ________ is the compound containing the reduced element. Find the oxidation number for each and determine what is oxidized, reduced, oxidizing agent, and reducing agent: Fe2O3(s) + 3 CO(g) --> 2Fe(l) + 3 CO2(g) 10.2 All reactions are redox reactions. An ________ is a list of metals from most likely to react in a chemical reaction to least likely to react. More likely to react means ____ likely to be found in a compound, rather than a compound.
