The population census of a city shows that its population has grown in the last decade. This growth has surpassed the city’s ability to provide sufficient water to its people. The city is located about 10 miles from the ocean and has a dry climate. Based on your research and the list of criteria and constraints from part A, suggest a technology to use in this city. Defend your choice with a valid explanation.

The answer for this is a

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⁻
