1)Balance the following chemical reaction, if necessary. Identify the reactant that is Oxidized and the reactant that is reduced. Write out the separate oxidation and reduction reaction equations. noilbse Fe2O03(s)- Fe(s) + O2(g) Speco Oxidized: Reduced: 2) Classify the reaction above as one of the following five types: Circle one. Single Replacement Decomposition Combination Double Replacement Combustion
Choose a chemical reaction to discuss. Give a balanced equation to represent the reaction, tell the type of chemical reaction it is and give one mole relationship for the reaction. You should have one that is combination, decomposition, single replacement, double replacement, oxidation/reduction, or combustion. Not using: 2H2 (g) + O2 (g) yields 2H2O(g) -OR - N2 + 3H2 yields 2NH3
