For the following equation determine the oxidation number for each atom in the equation and identify whether the reaction is a redox reaction or not. If the reaction is redox, identify what is oxidized, what is reduced, the oxidizing agent, and the reducing agent. If it is not a redox reaction, put NA those answer blocks. HCl + NH3 –> NH4Cl Reactants Oxidation Numbers: N [fay1] H [fay2] Cl [fay3] Product Oxidation Numbers N [fay4] H [fay5] Cl [fay6] Is this a redox reaction? [fay7] If it is, what is element is oxidized? [fay8] What element is reduced? [fay9] What element is the oxidizing agent? [fay10] What is the reducing agent? [fay11]
