The solutions which obey raoult's law at every range of concentration and at all temperatures are called ideal solutions. we can obtain ideal solutions by mixing two ideal components having similar molecular size and structure. for example, a misture of two liquids a and b. the formed solution will experience several intermolecular forces of attractions inside it, which will be: ·a-a intermolecular forces of attraction · b-b intermolecular forces of attraction ·a-b intermolecular forces of attraction

I’ve taken this before! the answer isa ^.^

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⁻
