Redox practice like in a previous module we will use this for both lessons. for lesson 1, only label the oxidation numbers of each element in the ten problems. you may type out the numbers making sure to be clear which element has which oxidation number or you may choose to hand write this and upload a clear picture of your work instead. regardless, save this work as you will expand upon this work in lesson 2! 1. mg + hcl  h2 + mgcl2 2. fe + o2  fe2o3 3. kclo3  kcl + o2 4. cu + o2  cuo\
