I have been sick the past few days and missed much Chemistry work if you could explain each interaction that would be great.

Use a magnet to separate iron, evaporate water, i'm not sure how to separate the other two i'm sorry but good luck

Electron equations of the given changes are as follow,a)                              cu      →      cu⁺²  + 2e⁻b)                              mg⁺²  +  2 e⁻      →      mgc)                              cl⁻    →      cl  +  1e⁻d)                              s  +  2 e⁻    →      s²⁻e)                                o²⁻      →      o  +  2 e⁻f)                              p  +  3 e⁻    →      p³⁻g)                              fe²⁺    →      fe³⁺  + 1 e⁻h)                              s²⁻    →      s⁴⁺  +  6 e⁻

1. i don't know.2. bitter taste, feels slippery, contains hydroxide or produces it in a solution.3. 104.i don't know.5. electrons.hope this somewhat!
