Fоr the fоllоwing equаtion determine the oxidаtion number for eаch atom in the equation and identify whether the reaction is a redox reaction or not (yes or no). Remember to a + before positive charges and a - before negative charges. Every box must have a number. If the reaction is redox, identify what element is oxidized, what element is reduced, the oxidizing agent, and the reducing agent. If it is not a redox reaction put NA in the remaining answers. Note – hydrogen shows up in two places in the products. Base your answer on the diatomic hydrogen (H2) in the product. Ca + 2H2O --> Ca(OH)2 + H2 Reactants Oxidation Numbers: Ca  [red1] H    [red2] O    [red3] Product Oxidation Numbers Ca  [red4] H    [red5] O    [red6] Is this a redox reaction?  [red7] If it is, what is element is oxidized?  [red8] What element is reduced? [red9] What element is the oxidizing agent?   [red10] What is the reducing agent? [red11]
