When 100 ml of 1.0 m na3po4 is mixed with 100 ml of 1.0 m agno3,

a yellow precipitate forms and ag+ becomes negligibly small. which

of the following is the correct listing of the ions remaining in solution

in order of increasing concentration?

(a) po43- < no3- < na+

(b) po43- < na+ < no3-

(c) no3- < po43- < na+

(d) na+ < no3- < po43-

(e) na+ < po43- < no3-

False because saturated fatty acids contain only single bond

The answer is c) pyrite

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⁻
